5.1 This test method is an index test for determining the puncture resistance of geomembranes and related products. The use of this test method is to establish an index value by providing standard criteria and a basis for uniform reporting.5.2 This test method is considered satisfactory for acceptance testing of commercial shipments of geomembranes and related materials since the test method has been used extensively in the trade for acceptance testing.5.2.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.1.1 This test method is used to measure the index puncture resistance of geomembranes and related products.1.2 The use of Test Method D4833/D4833M may be inappropriate for testing some woven geotextiles or related products which have large openings, such as geonets and geogrids.1.3 It is recommended that geotextile and geotextile related products be tested using Test Method D6241.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5 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.1.6 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 Use of this guide can be beneficial in determining the relative effectiveness of building systems as it relates to potential protection from passage of products of combustion between building spaces under both ambient and elevated temperatures.5.2 Determining the relative effectiveness of a building system to limit the total air leakage between building spaces is important in the evaluation and selection of potential construction components to meet desired performance requirements for a building.5.3 To properly assess the relative effectiveness of a building system’s total air leakage rate, a guide as to how to aggregate the individual component air leakage rates into a total air leakage rate for the building system is needed.5.4 It is the intent of this guide to provide a methodology for the conversion of individual component air leakage rates into common values that can be aggregated into a total air leakage rate for a building system, thus providing a means for establishing the relative effectiveness of various building systems to resist the passage of products of combustion.1.1 This guide provides a method of evaluating the relative effectiveness of building systems to resist the passage of smoke.1.2 The method of evaluating the relative effectiveness of a building system is based on the aggregation of leakage rates of openings, penetrations, joints, and interfaces of the construction elements forming the building system.1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This test method is considered satisfactory for manufacturing quality control testing of a specific geosynthetic; however, caution is advised since information about between-laboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable.5.1.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. Test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using the appropriate statistical analysis and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results with consideration to the known bias.5.2 This test method is not suitable for very limp geosynthetics or those that show a marked tendency to curl or twist at a cut edge.5.3 The stiffness of a geosynthetic may change with storage.5.4 No evidence has been found showing that bending length is dependent on specimen width. The tendency for specimens to curl or twist will affect the result, because of the rigidity provided at the edge. Consequently, the edge effect is less of an issue for a wider strip.1.1 This test method covers the measurement of stiffness properties of geogrids, geotextiles, and geogrid-geotextile composites, all of which are referred to as geosynthetics within this test method. Bending length is measured and flexural rigidity is calculated through use of the cantilever test procedure.1.1.1 This test method employs the principle of cantilever bending of the geosynthetic under its own mass.1.2 This test method applies to geogrids, geotextiles, and geogrid-geotextile composites.1.3 This test method is for manufacturing quality control purposes only, to ensure uniformity and consistency of flexural rigidity for a specific product from roll to roll and lot to lot.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This practice can be used to establish the validity of the results obtained by an infrared (IR) spectrophotometer or Raman spectrometer at the time the calibration is developed. The ongoing validation of PPTMRs produced by analysis of unknown samples using the multivariate model is covered separately (see for example, Practice D6122).5.2 The multivariate calibration procedures define the range over which measurements are valid and demonstrate whether the accuracy and precision of the analysis outputs meet user requirements.5.3 This practice describes sampling procedures that must be followed to ensure that the sample which is analyzed by the spectrophotometer or spectrometer is the same as the sample analyzed by the PTM. The sampling procedures apply to analyses done on lab analyzers, at-line analyzers, and online analyzers.1.1 This practice covers a guide for the multivariate calibration of infrared (IR) spectrophotometers and Raman spectrometers used in determining the physical, chemical, and performance properties of petroleum products, liquid fuels including biofuels, and lubricants. This practice is applicable to analyses conducted in the near infrared (NIR) spectral region (roughly 780 nm to 2500 nm) through the mid infrared (MIR) spectral region (roughly 4000 cm-1 to 40  cm-1). For Raman analyses, this practice is generally applied to Stokes shifted bands that occur roughly 400 cm-1 to 4000 cm-1 below the frequency of the excitation.NOTE 1: While the practice described herein deals specifically with mid-infrared, near-infrared, and Raman analysis, much of the mathematical and procedural detail contained herein is also applicable for multivariate quantitative analysis done using other forms of spectroscopy. The user is cautioned that typical and best practices for multivariate quantitative analysis using other forms of spectroscopy may differ from the practice described herein for mid-infrared, near-infrared, and Raman spectroscopies.1.2 Procedures for collecting and treating data for developing IR and Raman calibrations are outlined. Definitions, terms, and calibration techniques are described. The calibration establishes a multivariate correlation between the spectral features and the properties to be predicted. This correlation is herein referred to as the multivariate model. Criteria for validating the performance of the multivariate model are described. The properties against which a multivariate model is calibrated and validated are measured by Primary Test Methods (PTMs) and the results of the PTM measurement are herein referred to as Primary Test Method Results (PTMR). The analysis of the spectra using the multivariate model produces a Predicted Primary Test Method Result (PPTMR).1.3 The implementation of this practice requires that the IR spectrophotometer or Raman spectrometer has been installed in compliance with the manufacturer's specifications. In addition, it assumes that, at the time of calibration, validation, and analysis, the analyzer is operating at the conditions specified by the manufacturer. The practice includes instrument performance tests which define the instrument performance at the time of calibration, and which qualify the instrument by demonstrating comparable performance during validation and analysis.1.4 This practice covers techniques that are routinely applied for online, at-line, and laboratory quantitative analysis. The practice outlined covers the general cases for liquids and solids that are single phase homogeneous samples when presented to the analyzers. Online application is limited by sample viscosity and the ability to introduce sample to the analyzer. All techniques covered require the use of a computer for data collection and analysis.1.5 This practice is most typically applied when the spectra and the PTMR against which the analysis is calibrated are measured on the same sample. However, for some applications, spectra may be measured on a basestock and the PTMR may be measured on the same basestock after constant level additivation.1.5.1 Biofuel applications will typically fall into three categories.1.5.1.1 The spectra and the PTM both measure the finished biofuel blend.1.5.1.2 The spectra are measured on a petroleum derived blendstock, and the PTM measures the same blendstock after a constant level additivation with the biocomponent.1.5.1.3 The spectra and PTM both measured the petroleum derived blendstock, and the PPTMRs from the multivariate model are used as inputs into a second model which predicts the results obtained when the PTM is applied to the analysis of the finished blended product. The practice described herein only applies to the first of these two models.1.6 This practice includes a checklist in Annex A2 against which multivariate calibrations can be examined to determine if they conform to the requirements defined herein.1.7 For some multivariate spectroscopic analyses, interferences and matrix effects are sufficiently small that it is possible to calibrate using mixtures that contain substantially fewer chemical components than the samples that will ultimately be analyzed. While these surrogate methods generally make use of the multivariate mathematics described herein, they do not conform to procedures described herein, specifically with respect to the handling of outliers. Surrogate methods may indicate that they make use of the mathematics described herein, but they should not claim to follow the procedures described herein. Test Methods D5845 and D6277 are examples of surrogate methods.1.8 Disclaimer of Liability as to Patented Inventions—Neither ASTM International nor an ASTM committee shall be responsible for identifying all patents under which a license is required in using this document. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.1.9 The values stated in SI units are to be regarded as standard.

4.1 The principal purpose of irradiation is to reduce the number of pathogenic bacteria, such as Campylobacter, Escherichia coli 0157:H7, Listeria monocytogenes, Staphylococcus aureus or Salmonella spp., in processed meats and poultry to make these foods safer for human consumption.Note 3—Ionizing radiation doses below 10 kGy will reduce but not eliminate spores of pathogenic bacteria including those of Clostridium botulinum, Clostridium perfringens and Bacillus cereus.4.2 Irradiation treatment can extend the shelf life of processed meats and poultry by reducing the numbers of vegetative spoilage bacteria, such as Pseudomonas species and lactic acid bacilli.4.3 Irradiation treatment also inactivates parasites such as Trichinella spiralis and Toxoplasma gondii.4.4 Radiation processing of the final product in its packaging is a critical control point (CCP) of a Hazard Analysis of Critical Control Points (HACCP) concept for the production of Processed Meat and Poultry. It serves as an important measure to control any residual risk from pathogen microorganisms just before the product reaches the consumer.4.5 The “Recommended International Code of Practice for Radiation-processing of Food” (CAC/RCP 19-1979) of the Codex Alimentarius identifies the essential practices to be implemented to achieve effective radiation processing of food, in general, in a manner that maintains quality and yields food products that are safe and suitable for consumption.1.1 This guide outlines procedures for the irradiation of pre-packaged refrigerated and frozen processed meat and poultry products.Note 1—The Codex Alimentarius Commission defines “meat” (including poultry and game) as “the edible part of any mammal slaughtered in an abattoir,” and “poultry meat” as “the edible part of slaughtered domesticated birds, including chicken, turkeys, ducks, geese, guinea-fowls, or pigeons.” (CAC/RCP 13-1976)Note 2—Current U.S. regulations limit the definition of livestock species to cattle, sheep, swine, goat, horse, mule, or other equine and poultry species to chicken, turkey, duck, goose, and guinea (2, 3).1.2 This guide addresses all refrigerated and frozen meat and poultry products NOT covered by Guide F1356.1.3 This guide provides information regarding absorbed doses used for inactivation of parasites and reduction of bacterial load. Such doses are typically less than 10 kilogray (kGy).

4.1 This guide outlines sustainability factors for manufacturers to consider when comparing alternative chemicals or ingredients across the life cycle of a product.4.2 Methods exist for the evaluation of chemical hazards for product-chemical pairs. These methods are referenced in several regulatory, non-regulatory, and green building schemes and should be conducted as part of an analysis of this type.NOTE 1: Evaluation methods include, but are not limited to, Clean Production Action’s GreenScreen for Safer Chemicals,5 The United States Environmental Protection Agency’s Design for the Environment (DfE) Alternatives Assessment Criteria for Hazards Evaluation (Safer Choice) methodology and the National Academy of Sciences’ A Framework to Guide Selection of Chemical Alternatives.8 Regulatory schemes include laws such as the Safer Consumer Products Rule9 in California or the Registration, Evaluation, and Authorization of Chemicals (REACH)10 regulations in Europe. Green building schemes include the Leadership in Energy and Environmental Design (LEED)11 system by the USGBC, which references these indirectly through third-party certifications. However, neither these assessment tools nor the various schemes that reference them have set guidance for using the data in making decisions on which products and ingredients are ultimately the most sustainable.4.3 Similarly, many tools exist for measuring economic viability, such as value-models and cost analysis. There are also many tools and techniques for measuring social acceptance of products such as sales trends, voice of the customer and many other types of surveys.4.4 This guide acknowledges the need for determining a baseline for comparing the performance (environmental, economic, and social) of an existing product-chemical pair in a product with the possible/potential alternatives. As such, when using this guide, companies shall use the same study boundaries for the original baseline case and for all alternative options under assessment. Further, when feasible, the same assessment tools should also be used for all options being analyzed.4.5 Sustainability is a very holistic and encompassing concept. As such, many factors cross all three attributes of sustainability. While factors may be assigned one way in this guide, it is recognized the user has discretion to assign them to whatever attribute(s) they deem appropriate when performing this analysis. However, the user should consistently categorize among all analyses for the purpose of easy comparison.4.6 This guide is structured such that the impacts of each life cycle stage (that is, raw material acquisition, raw material transport, manufacturing, use, and end of life) are considered in their entirety for each attribute of sustainability (that is, social, economic, and ecological). Users of this guide also may wish to take an alternative approach by considering the impacts associated with all three attributes of sustainability (for example, social, economic, and ecological) for each life cycle stage before moving on to the next life cycle stage. This alternate approach may provide a different perspective regarding identifying areas of high impact within each life cycle stage.1.1 This guide covers sustainability factors for product manufacturers to consider when comparing alternative chemicals or ingredients across the life cycle of a product. Such an analysis could be used in product development, answering customer inquiries, or replying to regulatory requests, among others.1.2 This guide integrates many of the principles of green chemistry and green engineering in evaluating the factors across the social (including human health), economic, and ecological attributes in the use of a particular material and potential alternatives in a particular product.1.3 This guide provides an outline for the contents of a report of the results of the analysis, including an executive summary, detailed report, and retrospective.1.4 This guide does not provide guidance on how to perform chemical risk assessment, alternatives assessment, life-cycle assessment, or economic analysis, or how the alternatives decision-making framework will be completed.1.5 This guide does not suggest in what order the social, ecological, or economic attributes of sustainability should be evaluated or which one is most important. This is a decision of the company performing the decision-making evaluation.1.6 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.1.7 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.
