1.1 This software was developed to automate calculations within three ASTM standards: Practices D2777 (outlier removal section), D6091, and D6512.1.2 The program calculates detection estimates (DE) and quantitation estimates (QE) for the constant, straight-line, exponential, and hybrid (Rocke-Lorenzato) models of the variation of [inter or intra] laboratory standard deviation (ILSD) with concentration. Calculations are shown in the DE_QE worksheet and results are shown in the DLs & QLs worksheet. Several plots are generated showing how well each model fits the data. The least complex model to fit the data with adequate confidence must be used by the ASTM standards.NOTE 1: Modeling techniques automated in this practice and with this software have been shown to work well with most data sets. Users of this software are cautioned that with some, rare data sets, anomalous results may be obtained, and manual forcing of a different model may be required. It has been noted that for some data sets when an exponential model is selected, there may be a lack of convergence on a result or there may be a convergence on two separate results.1.3 Users of DQCALC should refer to Practices D2777, D6091, and D6512 for the specifics of the scope and application of the Practices.1.4 The IDE Practice (D6091) and the IQE Practice (D6512) are concerned with estimates of limits of detection and limits of quantitation based on inter-laboratory data. DQCALC may also be employed to calculate detection and quantitation estimates based on single laboratory data.1.5 The DQCALC Software consists of a Microsoft Excel3 workbook spreadsheet and associated macros and a user manual in Microsoft Word.3

5.1 This standard defines measurement procedures for estimating the risk of noise-induced hearing loss among users of noise producing equipment. It is applicable to ground vehicles, aircraft, watercraft, and mobile, transportable, and stationary equipment. The primary approach is to separately measure the sound level at operator ear locations for each normal operating condition. These levels can be combined with operational use scenarios and exposure criteria to define noise exposure severity. The data can also be used to define hearing protection requirements or administrative controls to preclude hearing hazards.5.2 The practice has the following limitations:5.2.1 The practice uses field portable measurement equipment.5.2.2 The practice produces data which may be compared with applicable criteria or limits if the limits are in terms of the quantities measured in this standard or which can be calculated from the measured data.1.1 This standard defines noise measurement procedures for estimating the risk of hearing loss among users of noise producing equipment. It is applicable to ground vehicles, aircraft, watercraft, and other mobile, transportable, or stationary equipment.1.2 This standard does not recommend noise exposure limit levels or criteria for any application discussed.1.3 The values stated in SI units are to be regarded as standard.

4.1 Uses—This practice is intended for use on a voluntary basis by parties who wish to conduct a BEPA on a building. The process defined in this practice involves the collection of building energy consumption information, some of which may be collected as part of E2018 PCA or E1527 ESA. The practice is intended primarily as an approach to conducting a standardized inquiry designed to identify representative building energy performance in connection with a commercial property involved in a real estate transaction. This practice is intended to reflect a commercially practical and reasonable inquiry.4.1.1 A number of states including CA, CO, WA and NJ, and more than three dozen cities, county and municipal governments, including Ann Arbor, MI, Atlanta, GA, Austin, TX, Berkeley, CA, Bloomington, MN, Boston, MA, Boulder, CO, Cambridge, MA, Chicago, IL, Chula Vista, CA, Columbus, OH, Denver, CO, Des Moines, IA, Edina, MN, Evanston, IL, Fort Collins, CO, Indianapolis, IN, Kansas City, MO, Los Angeles, CA, Miami, FL, Minneapolis, MN, Montgomery County, MD, New York City, NY, Orlando, FL, Philadelphia, PA, Pittsburgh, PA, Portland, ME, Portland, OR, Reno, NV, Salt Lake City, UT, San Diego, CA, San Francisco, CA, San Jose, CA, Seattle, WA, South Portland, ME, St. Louis, MO, St. Louis Park, MN, St. Paul, MN and Washington, D.C. have building energy performance benchmarking and reporting policies. Users in these locations must comply with applicable ordinances and regulations.4.2 Clarifications on Use: 4.2.1 Use in Conjunction with E2018 PCA or E1527 ESA—This practice, when added as a supplemental scope of work to a E2018 PCA or a E1527 ESA, is designed to assist the user and consultant in developing information about energy consumption in a building or buildings involved in a real estate transaction. The BEPA also has utility to a wide range of persons, including those who may not be involved in a real estate transaction.4.2.2 Independent Use—This practice may also be used independently of any other building assessment to determine building energy performance.4.2.3 Site-Specific—This practice is property-specific in that it relates to existing building energy performance. The practice is not intended to replace E2018 PCA or E1527 ESA conducted by a qualified consultant or individual, but rather to supplement it.4.3 Who May Conduct—A BEPA shall be performed by a qualified consultant or individual (hereafter referred to as the “Consultant”) with the education, training and experience necessary to perform the requirements of this practice (see Appendix X4). No practical approach can be designed to eliminate the role of professional judgment and the value and need for experience in the individual performing the inquiry. The professional experience of the Consultant is, consequently, important to the performance of this BEPA.4.4 Additional Services—As set forth in Section 13, additional services may be contracted for between the user and the Consultant. Such additional services may include issues not included within the scope of this practice. For example, the user or Consultant may wish to benchmark the building against similar buildings in the portfolio or in the same geographical area or identify select green building attributes that may contribute to the energy efficiency performance and/or the building’s valuation.4.4.1 Benchmarking Additional Service—Any benchmarking system selected relies on critical data in generating its output, so the validity of the data collection process directly impacts the integrity and usefulness of the benchmarking system’s results. Utilization of this practice and adoption of its data collection approach can serve to enhance the integrity of the benchmarking process for all transactional stakeholders in a standardized, fully transparent, uniform, and consistent manner. Notwithstanding, building energy consumption information should always be evaluated within the context in which it is collected and building energy consumption numbers should not be used without conveying this context. (Refer to Appendix X1 for additional information.)4.5 Principles—The following principles are an integral part of this practice and are intended to be referred to in resolving any ambiguity or exercising such discretion as is accorded the user or Consultant in performing a BEPA.4.5.1 Uncertainty Not Eliminated in BEPA—No BEPA practice can wholly eliminate uncertainty in determining the myriad of variables that can impact the energy consumption of a building on a property. The BEPA is intended to reduce, but not eliminate, uncertainty regarding the impact such variables can have on the energy consumption of a building.4.5.2 Not Exhaustive—This practice is not meant to be an exhaustive assessment. There is a point at which the cost of information obtained or the time required to gather it outweighs the usefulness of the information and, in fact, may be a material detriment to the orderly completion of a real estate transaction. One of the purposes of this practice is to identify a balance between the competing goals of limiting the costs and time demands inherent in performing a BEPA and the reduction of uncertainty about unknown conditions resulting from collecting additional information.4.5.3 Level of Inquiry is Variable—Not every building will warrant the same level of assessment. The appropriate level of assessment will be guided by the type of property subject to assessment and its complexity, the needs of the user, and the information already available or developed in the course of the inquiry.4.6 Rules of Engagement—The contractual and legal obligations between a Consultant and a user (and other parties, if any) are outside the scope of this practice. No specific legal relationship between the Consultant and user was considered during the preparation of this practice.1.1 Purpose—The purpose of this standard is to define a commercially useful practice in the United States of America for conducting a building energy performance assessment (BEPA) on a building involved in a commercial real estate transaction and subsequent reporting of the building energy performance information. The practice is intended to provide a methodology to the user for the collection, compilation, analysis, and reporting of building energy performance information associated with a commercial building. The practice may be used independently or as a voluntary supplement to Guide E2018 for property condition assessments or Practice E1527 for Phase I environmental site assessments. Utilization of this practice and performance of a BEPA is voluntary. If the property owner (for example, the seller) is unwilling or unable to provide building energy consumption and cost information, a BEPA cannot be performed.1.2 Building Energy Performance—This practice defines building energy performance as the building’s total annual energy consumption and cost for heating, cooling, electricity, and other related uses. Energy consumption, for example, includes total electricity purchased; purchased or delivered steam, hot water, or chilled water; natural gas; fuel oil; coal; propane; biomass; or any other matter consumed as fuel and any electricity generated on site from renewable/alternative energy systems (for example, wind energy generator technology, fuel cells, microturbines or solar photovoltaic systems).1.3 Objectives—Objectives in the development of this practice are to: (1) define a commercially useful practice for collecting, compiling, and analyzing building energy performance information associated with a building involved in a commercial real estate transaction; (2) facilitate consistency in the collection, compilation, analysis, and reporting of building energy performance information as may be required under building benchmarking, labeling, disclosure, or mandatory auditing regulations; (3) supplement as needed a property condition assessment conducted in accordance with Guide E2018 or an environmental site assessment conducted in accordance with Practice E1527; (4) provide that the process for building energy performance data collection, compilation, analysis, and reporting is consistent, transparent, practical and reasonable; and (5) provide an industry standard for the conduct of a BEPA on a building involved in a commercial real estate transaction, subject to existing statutes and regulations which may differ in terms of scope and practice.1.4 Documentation—The scope of this practice includes data collection, compilation and reporting requirements. Documentation of all sources, records, and resources relied upon in the investigation is provided in the report.1.5 Considerations Outside the —The use of this practice is limited to the collection, compilation, and analysis of building energy performance information as defined by this practice for real estate transactions in the United States of America. While this information may be used to facilitate building benchmarking, labeling, rating or ranking, reporting of building energy performance information between a seller and a buyer or a landlord and a tenant on a voluntary basis or as may be required by building benchmarking, labeling, disclosure or mandatory auditing regulations applicable to the building, or any other use, such use is beyond the scope of this practice. This ASTM Standard Practice does not supersede existing statutes and regulations.1.6 Organization of This Practice—This practice has 13 sections and 11 appendices. The appendices are included for informational purposes only and are not part of the procedures prescribed in this practice.Section 1 Describes the scope of the practice.Section 2 Identifies referenced documents.Section 3 Provides terminology pertinent to the practice.Section 4 Discusses the significance and use of the practice.Section 5 Discusses the relationship between this practice and ASTM Guide E2018 or ASTM Practice E1527.Section 6 Describes the user's responsibilities under this practice.Section 7 Describes the BEPA process.Section 8 Describes the site visit and walk-through.Section 9 Discusses interviews with owner , operator, or key site manager.Section 10 Describes records collection for the BEPA process.Section 11 Provides the records analysis methodology for building energy consumption data.Section 12 Focuses on BEPA report preparation and reporting of building energy consumption information.Section 13 Identifies non-scope considerations.Appendix X1 Provides the legal background on federal, state, or local building energy consumption disclosure legislation and regulation.Appendix X2 Identifies building energy performance and sustainability labeling programs.Appendix X3 Discusses government and utility energy efficiency incentives and grants.Appendix X4 Provides guidance on suggested qualifications for the consultant conducting the BEPA.Appendix X5 Information that can be collected from the property owner/operator/key site manager.Appendix X6 Provides a recommended table of contents and report format for the BEPA.Appendix X7 Provides general property types with categories and subcategories that can impact building energy consumption.Appendix X8 Provides a general commercial building survey checklist.Appendix X9 Presents carbon emission estimation methodology associated with combustion processes related to energy consumption in a commercial building.Appendix X10 Provides common no-cost/low-cost energy saving measures for commercial buildings.Appendix X11 Provides illustrative example of building site energy consumption calculations.1.7 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.8 This practice cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard practice is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this practice be applied without consideration of a building’s many unique aspects. The word “standard” in the title means only that the practice has been approved through the ASTM consensus process.1.9 Nothing in this practice is intended to create or imply the existence of a legal obligation for reporting of energy, performance, or other building-related information. Any consideration of whether such an obligation exists under any federal, state, local, or common law is beyond the scope of this practice.1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The objective of this practice is to provide a uniform procedure for assessing the resistance of medical glove materials to permeation by chemotherapy drugs, and to establish a consistent reporting of the test data.1.1 This practice covers a protocol for the assessment of resistance of medical glove materials to permeation by potentially hazardous cancer chemotherapy drugs under conditions of continuous contact. An assessment is made based on the permeation (breakthrough) of nine chemotherapy drugs through the glove material over a certain period of time.1.2 It is emphasized that the conditions used in this assessment are intended to approximate the worst-case condition for clinical uses. The data should be restricted to use on a relative basis when comparing glove materials.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This practice can be used to determine if a constant, proportional, or linear bias correction can improve the degree of agreement between two methods that purport to measure the same property of a material.5.2 The bias correction developed in this practice can be applied to a single result (X) obtained from one test method (method X) to obtain a predicted result ( Y^) for the other test method (method Y).NOTE 6: Users are cautioned to ensure that Y^ is within the scope of method Y before its use.5.3 The between methods reproducibility established by this practice can be used to construct an interval around Y^ that would contain the result of test method Y, if it were conducted, with approximately 95 % probability.5.4 This practice can be used to guide commercial agreements and product disposition decisions involving test methods that have been evaluated relative to each other in accordance with this practice.5.5 The magnitude of a statistically detectable bias is directly related to the uncertainties of the statistics from the experimental study. These uncertainties are related to both the size of the data set and the precision of the processes being studied. A large data set, or, highly precise test method(s), or both, can reduce the uncertainties of experimental statistics to the point where the “statistically detectable” bias can become “trivially small,” or be considered of no practical consequence in the intended use of the test method under study. Therefore, users of this practice are advised to determine in advance as to the magnitude of bias correction below which they would consider it to be unnecessary, or, of no practical concern for the intended application prior to execution of this practice.NOTE 7: It should be noted that the determination of this minimum bias of no practical concern is not a statistical decision, but rather, a subjective decision that is directly dependent on the application requirements of the users.1.1 This practice covers statistical methodology for assessing the expected agreement between two different standard test methods that purport to measure the same property of a material, and for the purpose of deciding if a simple linear bias correction can further improve the expected agreement. It is intended for use with results obtained from interlaboratory studies meeting the requirement of Practice D6300 or equivalent (for example, ISO 4259). The interlaboratory studies shall be conducted on at least ten materials in common that among them span the intersecting scopes of the test methods, and results shall be obtained from at least six laboratories using each method. Requirements in this practice shall be met in order for the assessment to be considered suitable for publication in either method, if such publication includes claim to have been carried out in compliance with this practice. Any such publication shall include mandatory information regarding certain details of the assessment outcome as specified in the Report section of this practice.1.2 The statistical methodology is based on the premise that a bias correction will not be needed. In the absence of strong statistical evidence that a bias correction would result in better agreement between the two methods, a bias correction is not made. If a bias correction is required, then the parsimony principle is followed whereby a simple correction is to be favored over a more complex one.NOTE 1: Failure to adhere to the parsimony principle generally results in models that are over-fitted and do not perform well in practice.1.3 The bias corrections of this practice are limited to a constant correction, proportional correction, or a linear (proportional + constant) correction.1.4 The bias-correction methods of this practice are method symmetric, in the sense that equivalent corrections are obtained regardless of which method is bias-corrected to match the other.1.5 A methodology is presented for establishing the numerical limit (designated by this practice as the between methods reproducibility) that would be exceeded about 5 % of the time (one case in 20 in the long run) for the difference between two results where each result is obtained by a different operator using different apparatus and each applying one of the two methods X and Y on identical material, where one of the methods has been appropriately bias-corrected in accordance with this practice, in the normal and correct operation of both test methods.NOTE 2: In earlier versions of this standard practice, the term “cross-method reproducibility” was used in place of the term “between methods reproducibility.” The change was made because the “between methods reproducibility” term is more intuitive and less confusing. It is important to note that these two terms are synonymous and interchangeable with one another, especially in cases where the “cross-method reproducibility” term was subsequently referenced by name in methods where a D6708 assessment was performed, before the change in terminology in this standard practice was adopted.NOTE 3: Users are cautioned against applying the between methods reproducibility as calculated from this practice to materials that are significantly different in composition from those actually studied, as the ability of this practice to detect and address sample-specific biases (see 6.7) is dependent on the materials selected for the interlaboratory study. When sample-specific biases are present, the types and ranges of samples may need to be expanded significantly from the minimum of ten as specified in this practice in order to obtain a more comprehensive and reliable between methods reproducibility that adequately cover the range of sample-specific biases for different types of materials.1.6 This practice is intended for test methods which measure quantitative (numerical) properties of petroleum or petroleum products.1.7 The statistical calculations of this practice are also applicable for assessing the expected agreement between two different test methods that purport to measure the same property of a material using results that are not as described in 1.1, provided the results and associated statistics from each test method are obtained from a specifically designed multi-lab study or from a proficiency testing program (e.g.: ILCP) where for each sample a single result is provided by each lab for each test method. The comparison sample set shall comprise at least ten different materials that span the intersecting scopes of the test methods with no material exceeding the leverage requirement in Practice D6300. Results and statistics shall meet requirements in 1.7.1. Requirements in this practice shall be met in order for the assessment to be considered suitable for publication in either method, if such publication includes claim to have been carried out in compliance with this practice. Any such publication shall include mandatory information regarding certain details of the assessment as specified in the Report section of this practice. RXY shall be based on the published reproducibility of the methods.1.7.1 For each test method and sample, results and statistics used to perform the assessment in 1.7 shall meet the following requirements:(1) No. of results (N) ≥ 10,(2) Anderson Darling statistic ≤ 1.12 (based on Normal Distribution),(3) Standard Error (sesample) is calculated using published reproducibility evaluated at the sample mean, N, and the factor 2.8 as follows:(4) sesample is numerically less than [Rpub / (2.8 √10 )], and(5) Sample standard deviation (ssample) per root-mean-square technique is not statistically greater than Rpub / 2.8 for at least 80 % of the samples in the comparison data set based on an F-test using 30 as the assumed degrees of freedom for Rpub, and (N − 1) for ssample at the 0.05 significance level.1.8 The methodology in this practice can also be used to perform linear regression analysis between two variables (X, Y) where there is known uncertainty in both variables that may or may not be constant over the regression range. The common acronym used to describe this type of linear regression is ReXY (Regression with errors in X and Y). The ReXY technique for assessing the correlation between two variables as described in this practice can be used for investigative applications where the strict data input requirement may not be met, but the outcome can still be useful for the intended application. Use of this practice for ReXY should be conducted under the tutelage of subject matter experts familiar with the statistical theory and techniques described in this practice, the methodologies associated with the production and collection of the results to be used for the regression analysis, and interpretation of assessment outcome relative to the intended application.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

For additional information on nuclear maintenance coating work, refer to ASTM MNL8.44.2 A coatings monitoring program enables early identification and detection of potential problems in coating systems. Some CSL I coating systems may be known in advance to be suspect, deficient, or unqualified. Monitoring coating performance will assist in developing follow-up procedures to resolve any significant deficiency relative to coating work.4.3 Degraded coatings may generate debris under design basis accident conditions that could adversely affect the performance of the post-accident safety systems. A coatings monitoring program may be required to fulfill safety analysis report and generic letter commitments for CSL I coating work in a nuclear power plant facility.1.1 This standard covers procedures for establishing a monitoring program for condition assessment of Coating Service Level (CSL) I coating systems in operating nuclear power plants. Monitoring is an ongoing process of evaluating the condition and performance of the in-service coating systems.1.2 It is the intent of this standard to provide a recommended basis for establishing a coatings condition assessment program, not to mandate a singular basis for all programs. Variations or simplifications of the program described in this standard may be appropriate for each operating nuclear power plant depending on their licensing commitments.1.3 This requirements of ASME Section XI, In-Service Inspection Subsections IWE and IWL are beyond the scope of this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This guide provides guidance on how a surrogate material can be selected and inserted into a field workflow for confidence checks and process assessments of on-site biological assessment technologies to demonstrate that the technology is working in the field environment in the hands of operators.4.2 Use of a surrogate material instead of an inactivated or attenuated biological agent (or its components) is beneficial due to (1) ease of production and handling, (2) ease of acquisition and transportation, (3) the ability to use the material with minimal equipment and facility constraints, for example, biosafety containment, and (4) minimized risk of contamination of personnel, equipment and the environment with a potential biological agent.4.3 This guide covers the basic design of confidence checks and process assessments that may be used to target (1) the workflow in the field, (2) the performance of the on-site biological assessment technology, and (3) the operator’s ability to process a material in the field workflow, in order to increase confidence in each component. These demonstrations provide emergency responders with insight into routine operation of a nucleic acid-based biological assessment technology and the opportunity to assess and demonstrate their capabilities according to a defined training program in their jurisdiction.4.4 This guide may be used to aid operators in the routine use of any nucleic acid-based on-site biological assessment technology. Using a surrogate material, operators are able to gain confidence in their ability to perform operations in the workflow and gather routine information (for example, operator performance, assessment results over time) in the field.4.5 This guide should be used in accordance with Practices E2458 and Guide E2770.4.6 This guide should be used according to the appropriate risk reduction measures (including personal protective equipment) that are needed for the biosafety level of the surrogate material (preferably Biosafety Level 1; the level should be verified with the provider of the surrogate material).4.7 This guide is not meant to provide performance characterization of biological agent assays used with on-site biological assessment technologies.1.1 This guide describes factors to consider when developing, selecting, and using a surrogate material for evaluating the operational performance of nucleic acid-based on-site biological assessment technologies. Operational performance includes the workflow, technology, operator, controls, and result reporting.1.2 Users of this guide include developers and manufacturers of on-site biological assessment technologies or surrogate materials, as well as the initial responder community and other operators of the technologies.1.3 This guide recommends the use of surrogate materials to support training; improve the knowledge, skills, and confidence of operators; and enable confidence check and process assessment demonstrations in support of jurisdictional biothreat mission capabilities as recommended in Guide E2770, Section 8.1.4 This guide recommends the use of surrogate materials in combination with a training program as articulated in Guide E2770 and coordinated among the initial responder organization, hazardous materials response unit, Urban Search and Rescue (US&R) team, National Guard Civil Support Team (CST), Laboratory Response Network (LRN) reference laboratory, local law enforcement, the Federal Bureau of Investigation (FBI), and other agencies as defined by jurisdictional protocols.1.5 This guide recommends the selection of a surrogate material that challenges the workflow in a way similar to the challenge imposed by suspected biological agents encountered in real-world emergency response scenarios while posing minimal health and safety risks.1.6 This guide describes considerations when using a surrogate material for a confidence check of nucleic acid-based on-site biological assessment technologies.1.7 This guide describes factors involved in the use of a surrogate material to perform a process assessment when the operator has access to well-characterized nucleic acid-based assays specific to the surrogate material that enable the operator to target the analytical process applied to on-site biological assessment.1.8 This guide does not replace third-party validation of on-site biological assessment technologies to assess the ability of the technologies to correctly detect and identify a biological agent. This guide recommends that all on-site biological assessment technologies be demonstrated to perform according to internationally recognized consensus standards (for example, AOAC Standard Method Performance Requirements) as consistent with Guide E2770 and Practices E2458.1.9 For the purposes of this guide, sample collection should be performed according to Practices E2458.1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
