4.1 This practice is intended to assist the user, in particular the power-plant operations and maintenance departments, to maintain effective lubrication of all parts of the turbine and guard against the onset of problems associated with oil degradation and contamination. The values of the various test parameters mentioned in this practice are purely indicative. In fact, for proper interpretation of the results, many factors, such as type of equipment, operation workload, design of the lubricating oil circuit, and top-up level, should be taken into account.1.1 This practice covers the requirements for the effective monitoring of mineral turbine oils in service in steam and gas turbines, as individual or combined cycle turbines, used for power generation. This practice includes sampling and testing schedules to validate the condition of the lubricant through its life cycle and by ensuring required improvements to bring the present condition of the lubricant within the acceptable targets. This practice is not intended for condition monitoring of lubricants for auxiliary equipment; it is recommended that the appropriate practice be consulted (see Practice D6224).1.2 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.1.3 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 LCC analysis is an economic method to evaluate alternatives that are characterized by differing cash flows over the designated project design life. The method entails calculating the LCC of each alternative capable of satisfying the functional requirements of the project and comparing them to determine which have the lowest estimated LCC over the project design life.5.2 The LCC method is particularly suitable for determining whether the higher initial cost of an alternative is economically justified by reductions in future costs (for example, operating maintenance, rehabilitation, or replacement) when compared to an alternative with lower initial costs but higher future costs. If a design alternative has both a lower initial cost and lower future costs than other alternatives, an LCC analysis is not necessary to show the former is the economically preferable choice.1.1 This practice establishes a procedure for using life cycle cost (LCC) analysis techniques to evaluate alternative drainage system designs, using plastic pipe that satisfy the same functional requirements.1.2 The LCC technique measures the present value of all relevant costs to install, operate, and maintain alternative drainage systems such as engineering, construction, maintenance, rehabilitation, or replacement over a specified period of time. The practice also accommodates any remaining residual or salvage value.1.3 The decision maker, using the results of the LCC analysis, can then identify the alternative(s) with the lowest estimated total cost based on the present value of all costs.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.

1.1 This guide covers a common framework and set of principles for potential users, such as product manufacturers, environmental analysts, consultants, architects, and the building industry in general. It describes a framework for life cycle inventory analysis, and describes various options and aspects of Impact Assessment and Interpretation.1.2 The complexity and level of detail of an LCA will vary greatly depending on the material/product or system studied, the purpose and use of the study, the intended users of the study, and the resources committed to complete the study. The level of detail can range from generic to material/product specific.1.3 This guide does not describe in detail the actual techniques for performing a LCA.1.4 LCA is an emerging methodology, which is still evolving. This guide will present its concepts and major features. It should enable the user to better understand LCA and its application to building materials/products, and help to identify sources of additional information and guidance. LCA is only one of many tools designed to aid in environmental evaluation and decision making.1.5 The component phases of LCA, including goal definition and scoping, inventory, impact assessment, interpretation, and the various methodologies used in these phases are in various stages of development. Consequently, the results of an LCA must be understood in the context of their completeness and accuracy and must be applied appropriately. LCA does not necessarily proceed as a linear process through these phases but is conducted in an iterative fashion.

5.1 Certified reference materials (CRMs) prepared from nuclear materials are well characterized, traceable, and sufficiently homogenous and stable for their intended use. Usually they are certified using the most unbiased and precise measurement methods available, often with more than one laboratory being used on a national or international level. CRMs are at the top of the metrological hierarchy of reference materials. A graphical representation of a typical national nuclear measurement system is shown in Fig. 3.FIG. 3 Typical National Nuclear Measurement System5.2 Working reference materials (WRMs) need to have quality characteristics that are similar to CRMs, although the rigor used to achieve those characteristics is not usually as stringent as for CRMs. Similarly, production of WRMs should be in accordance with applicable requirements of ISO 17034. Where possible, CRMs are typically used to calibrate the methods used for establishing reference values assigned to WRMs, thus providing traceability to CRMs as required by ISO/IEC 17025. A WRM is normally prepared for a specific application.5.3 Because of the importance of having highly reliable measurement data from nuclear material analysis, particularly for material control and accountability purposes, CRMs are used for calibration when available. However, CRMs prepared from nuclear materials are not always available for specific applications. Thus, there may be a need for a laboratory to prepare nuclear material WRMs to meet specific needs; for example, to match the matrix in process samples. In such cases, a WRM can be tailored to meet specific needs of a process or laboratory. Also, CRM supply may be too limited for use in the quantities needed for long-term, routine use. When properly prepared, WRMs will serve equally well as CRMs for most applications, and using WRMs will help preserve supplies of CRMs.5.4 Difficulties may be encountered in the preparation of RMs from nuclear materials because of the chemical and physical properties of the materials. Chemical instabilities, problems in ensuring stoichiometry, homogeneity, and radioactivity are among the factors to be considered, with all three factors being involved with some materials. Those preparing WRMs from nuclear materials need to be aware of how these factors may affect preparation, as well as being aware of the other criteria governing the preparation of reliable WRMs.5.5 While use of WRMs provides benefits for the laboratory, it is important to observe the distinction between WRMs, which are prepared by a laboratory for use by that laboratory (or, in some cases, an affiliated satellite laboratory or production facility served by the laboratory), and CRMs which provide certificates of analysis (in accordance with ISO Guide 31) and can be offered for sale.1.1 This guide covers the preparation and characterization of working reference materials (WRM) that are produced by a laboratory for its own use in the analysis of nuclear fuel cycle materials. Guidance is provided for proper planning, preparation, packaging, and storage; requirements for characterization; homogeneity and stability considerations; and value assignment. When traceability to SI is desired for a WRM, it will be achieved by a defined, statistically sound characterization process that is traceable to a certified value on a certified reference materials. While the guidance provided is generic for nuclear fuel cycle materials, detailed examples for some materials are provided in the appendixes.1.2 This guide does not apply to the production and characterization of certified reference materials (CRM). Refer to ISO 17034 and ISO Guide 35 for guidance on reference material production, characterization, certification, sale, and distribution requirements.1.3 The information provided by this guide is found in the following sections:  SectionPerform WRM Planning 6Prepare and Process Materials 7Packaging and Storage of Materials 8Perform Homogeneity Study 9Perform Stability Studies 10Characterize Materials 11Perform Uncertainty Analysis 12Produce Documentation 13Carry Out WRM Utilization and Monitoring 141.4 The values stated in SI units are to be regarded as standard. The non-SI units of molar, M, and normal, N, are also regarded as standard. Any non-SI units of measurement shown in parentheses are for information only.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.

3.1 The significance of the LCA method is that it is a comprehensive technique for taking into account all relevant monetary values over the project design life and provides a measure of the total cost of the material, system, or structure.3.2 The LCA method can be effectively applied in both the preconstruction and bid stages of projects. After bids are taken, real costs can be used instead of estimates.1.1 This practice covers procedures for least cost (life cycle) analysis (LCA) of materials, systems, or structures proposed for use in the construction of concrete culvert, storm sewer, and sanitary sewer systems.NOTE 1: As intended in this practice, examples of analyses include, but are not limited to the following: (1) materials-pipe linings and coatings, concrete wall thicknesses, cements, additives, etc.; (2) systems-circular pipe, box sections, multiple lines, force mains, etc.; and (3) structures-wet and dry wells, pump and lift stations, etc.1.2 The LCA method includes costs associated with planning, engineering, construction (bid price), maintenance, rehabilitation, replacement, and cost deductions for any residual value at the end of the proposed project design life.1.3 For each material, system, or structure, the LCA method determines in present value constant dollars, the total of all initial and future costs over the project design life, and deducts any residual value.1.4 Major factors in the LCA method include project design life, service life, and relevant interest and inflation rates.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 The purpose of this test method is to define a procedure for testing components being considered for installation into a high-purity gas distribution system. Application of this test method is expected to yield comparable data among components tested for the purposes of qualification for this installation.1.1 This test method covers the testing of automatic valves for cycle life utilizing static, no-flow conditions. This no-flow condition is felt to be a realistic test to determine the valve's cycle life.1.2 This test method applies to automatically operated valves. It is intended to measure the cycle life of the valve itself including the seat and body sealing. It does not include cycle testing of the actuator. Testing must include both pressure testing and helium leak testing and must include vacuum test conditions when appropriate. This test method may be applied to a broad range of valve sizes.1.3 Limitations: 1.3.1 This test is not designed to evaluate the performance of the actuator. This test method addresses the gas system contamination aspects of the valve performance, that is, seat and body leakage and diaphragm or bellows failure. If the actuator fails during the evaluation, the valve is deemed as a failure.1.3.2 While the requirements of a valve's performance might include items such as particulate generation levels, this test method only attempts to evaluate cycle life and performance degradation as they relate to the ability of the valve to operate and shut off flow.1.3.3 This test method is written with the assumption that the operator understands the use of the apparatus at a level equivalent to six months of experience.1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.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. Specific hazard statements are given in Section 7.1.6 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.

4.1 Calibration is a fundamental part of making measurements and its effect on the quality of measurement data is significant. Thus, sufficient attention must be given to calibration when it is established for a measurement method so that the data produced will be acceptable. The use of an inappropriate calibration standard, inadequate instructions for calibration, and poor documentation of the calibration process are examples of circumstances that can adversely affect the validity of a calibration. Thus, the calibration process must conform to criteria established to ensure the validity of calibration results and any associated measurement data. Such criteria are given in Guide C1009, in which calibration is identified as a component of laboratory quality assurance (see Fig. 1). This guide expands upon those criteria to provide more comprehensive guidance for establishing calibration.FIG. 1 Quality Assurance of Analytical Laboratory Data4.2 The manner of calibration and other technical requirements for calibrating a measurement method are usually established when a method is first introduced into a laboratory, which may be through validation and qualification as defined by Guide C1068 (see Fig. 1). However, calibration involves more than the technical aspects of the calibration process. The other dimension of the process is the operational requirements that are necessary to ensure that calibration results are valid and that they are documented and verifiable should their integrity be questioned. The provisions of this guide provide those operational requirements and should be considered whenever calibration is planned and established.1.1 This guide provides the basis for establishing calibration for a measurement method typically used in an analytical chemistry laboratory analyzing nuclear materials. Guidance is included for such activities as preparing a calibration procedure, selecting a calibration standard, controlling calibrated equipment, and documenting calibration. The guide is generic and any required technical information specific for a given method must be obtained from other sources.1.2 The guidance information is provided in the following sections:  SectionGeneral Considerations 5Calibration Procedure 6Calibration Standard 7Control of Calibrated Equipment 8Documentation 9Keywords 101.3 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.

The forest products finishing industry has encountered difficulties in measuring the temperature of painted surfaces prior to, during, and after the curing process. The use of thermocouples is not entirely satisfactory because the thermocouple wires tend to conduct heat away too rapidly from the area where the temperature is being measured. Infrared radiation thermometers that are simple to operate can circumvent this difficulty. After calibration they are aimed at the surface, switched on, and the temperature read directly from an indicating gage. Note 1—Temperature-sensitive crayons, papers, and pellets may be successfully used to measure only the highest temperature reached by painted surfaces during the curing cycle. There are several different types of infrared radiation thermometers, including those based on lead sulfide or thermistor sensors and those that are simple thermal voltaic transducers. As such they respond to different wavelengths of infrared radiation and have different areas of applicability. Only instruments that have been evaluated are included in this practice.1.1 This practice is intended to serve as a guide in measuring with infrared instruments the temperature during the curing process of coatings applied to wood products. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Protection of a species requires prevention of unacceptable effects on the number, health, and uses of individuals of that species. A life-cycle toxicity test is conducted to determine changes in the numbers of individuals and offspring of a test species resulting from effects of the test material on survival, growth, gender ratios, endocrine function, genetic expression, fertility and reproduction (1-3).3 Information might also be obtained on effects of the material on the health (4) and uses of the species. 5.2 Published information about the sensitivities of several meiobenthic copepods to several common metals and organic toxicants have been reviewed (5). For most compounds tested/published to date, A. tenuiremis is acutely less sensitive than mysid and penaeid shrimp, similarly sensitive as amphipods, and often more sensitive than cladocerans (daphniids, specifically). Reference 96-h aqueous toxicity tests with cadmium at 30 g/kg salinity showed an LC50 for A. tenuiremis adults of 213 to 234 μg/L (Chandler, unpub.). Reference toxicant tests with sodium dodecyl sulfate showed a 96-h LC50 of 13.3 to 15.5 mg/L (Chandler,unpubl.). A. tenuiremis is a comparatively new toxicity test organism, and an extensive database of species sensitivity to multiple aqueous test compounds is not yet available. Relative to other harpacticoid copepod studies in the literature, A. tenuiremis is more chronically sensitive than all other species published to date where there is comparative data (5). 5.3 Results of life-cycle tests with A. tenuiremis can be used to predict long-term effects at the individual and population levels likely to occur on copepods in field situations as a result of exposure under comparable conditions (1,2). 5.4 Results of life-cycle tests with A. tenuiremis might be used to compare the chronic sensitivities of different species and the chronic toxicities of different materials, and also study the effects of various environmental factors such as temperature, pH, and ultraviolet light on results of such tests. 5.5 Results of life-cycle tests with A. tenuiremis might be an important consideration when assessing the hazards of materials to aquatic organisms (see Guide E1023) or when deriving water quality criteria for aquatic organisms (6). 5.6 Results of a life-cycle test with A. tenuiremis might be useful for predicting the results of chronic tests on the same test material with the same species in another water or with another species in the same or a different water. Most such predictions take into account results of acute toxicity tests, and so the usefulness of the results from a life-cycle toxicity test with A. tenuiremis is greatly increased by also reporting the results of an acute toxicity test (see Guide E729) conducted under the same environmental conditions. 5.7 Results of life-cycle tests with A. tenuiremis might be useful for studying the biological availability of, and structure-activity relationships between, test materials. 5.8 Results of life-cycle tests with A. tenuiremis will depend on temperature, quality of food, composition of seawater, condition of test organisms, and other factors. 5.9 Life-cycle tests with A. tenuiremis are conducted on copepods reared individually in microwells of 96-well microplates. Thus they can be useful for studying endocrine, pre-zygotic and gender-specific toxicities of test materials (1-3). 1.1 This guide describes procedures for obtaining laboratory data concerning the adverse effects of a test material added to seawater, but not to food, on the marine copepod Amphiascus tenuiremis , during continuous exposures of individuals, from immediately after birth, until after the beginning of reproduction using a 200 μL renewal microplate-culturing technique. The following data are checked and recorded during the test period: stage-specific survival, number of days it takes for development from a first stage nauplius to a reproductively mature copepod, gender ratios, number of days for a female to extrude first and subsequent broods, number of days between first (and subsequent) brood extrusion(s) and hatching of first-generation nauplii, number of hatched and surviving nauplii, number of unhatched or necrotic eggs and aborted unhatching eggsacs, and the total number of females able to produce viable offspring over the entire mating period. This microplate-based full life-cycle toxicity test has a duration of approximately 17 days for toxicants that do not delay development. These procedures probably will be useful for conducting life-cycle toxicity tests with other species of copepods, although modifications might be necessary. 1.2 These procedures are applicable to most chemicals, either individually, or in formulations, commercial products, or known mixtures, that can be measured accurately at the necessary concentration in water. With appropriate modifications these procedures can be used to conduct tests on temperature, dissolved oxygen, and pH and on such materials as aqueous effluents (see also Guide E1192), sediment pore waters, and surface waters. Renewal microplate tests might not be applicable to materials that have a high oxygen demand, are highly volatile, are rapidly transformed (biologically or chemically) in aqueous solutions, or are removed from test solutions in substantial quantities by the test chambers or organisms during the test. If the concentration of dissolved oxygen falls below 50 % of saturation, or the concentration of test material in the test solution decreases by more than 20 % between renewals, it might be desirable to renew the solutions more often. 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 and health practices and determine the applicability of regulatory requirements prior to use.

5.1 Protection of a species requires prevention of unacceptable effects on the number, weight, health, and uses of the individuals of that species. A life-cycle toxicity test is conducted to determine what changes in the numbers and weights of individuals of the test species result from effects of the test material on survival, growth, and reproduction. Information might also be obtained on effects of the material on the health and uses of the species.5.2 Results of life-cycle tests with mysids might be used to predict long-term effects likely to occur on mysids in field situations as a result of exposure under comparable conditions.5.3 Results of life-cycle tests with mysids might be used to compare the chronic sensitivities of different species and the chronic toxicities of different materials, and also to study the effects of various environmental factors on results of such tests.5.4 Results of life-cycle tests with mysids might be an important consideration when assessing the hazards of materials to aquatic organisms (see Guide E1023) or when deriving water quality criteria for aquatic organisms (1).45.5 Results of a life-cycle test with mysids might be useful for predicting the results of chronic tests on the same test material with the same species in another water or with another species in the same or a different water (2). Most such predictions take into account results of acute toxicity tests, and so the usefulness of the results from a life-cycle test with mysids is greatly increased by also reporting the results of an acute toxicity test (see Guide E729) conducted under the same conditions.5.6 Results of life-cycle tests with mysids might be useful for studying the biological availability of, and structure-activity relationships between, test materials.5.7 Results of life-cycle tests with mysids might be useful for predicting population effects on the same species in another water or with another species in the same or a different water (3).1.1 This guide describes procedures for obtaining laboratory data concerning the adverse effects of a test material added to dilution water, but not to food, on certain species of saltwater mysids during continuous exposure from immediately after birth until after the beginning of reproduction using the flow-through technique. These procedures will probably be useful for conducting life-cycle toxicity tests with other species of mysids, although modifications might be necessary.1.2 Other modifications of these procedures might be justified by special needs or circumstances. Although using appropriate procedures is more important than following prescribed procedures, results of tests conducted using unusual procedures are not likely to be comparable to results of many other tests. Comparison of results obtained using modified and unmodified versions of these procedures might provide useful information on new concepts and procedures for conducting life-cycle toxicity tests with saltwater mysids.1.3 These procedures are applicable to all chemicals, either individually or in formulations, commercial products, or known mixtures, that can be measured accurately at the necessary concentrations in water. With appropriate modifications, these procedures can be used to conduct tests on temperature, dissolved oxygen, and pH and on such materials as aqueous effluents (see also Guide E1192), leachates, oils, particulate matter, sediments, and surface waters.1.4 This guide is arranged as follows:  Section Referenced Documents 2Terminology 3Summary of Guide 4 5Hazards 7Apparatus 6 Facilities 6.1 Construction Materials 6.2 Metering System 6.3 Test Chambers 6.4 Cleaning 6.5 Acceptability 6.6Dilution Water 8 Requirements 8.1 Source 8.2 Treatment 8.3 Characterization 8.4Test Material 9 General 9.1 Stock Solution 9.2 Test Concentration(s) 9.3Test Organisms 10 Species 10.1 Age 10.2 Source 10.3 Brood Stock 10.4 Food 10.5 Handling 10.6 Harvesting Young 10.7 Quality 10.8Procedure 11 Experimental Design 11.1 Dissolved Oxygen 11.2 Temperature 11.3 Beginning the Test 11.4 Feeding 11.5 Cleaning 11.6 Duration of Test 11.7 Biological Data 11.8 Other Measurements 11.9Analytical Methodology 12Acceptability of Test 13Calculation 14Documentation 15Keywords 16Appendix    X1.
