1.1 This standard presents a matrix to identify existing and potentially needed standards for light water reactor (LWR) fuel reprocessing. 1.2 This matrix pertains to facilities for the reprocessing of LWR spent fuel including its dissolution and separation of the reusable nuclear materials from the waste byproducts and conversion of these products and byproducts to suitable forms for shipment off-site. 1.3 The matrix is defined as an array of fuel reprocessing systems and components as the horizontal axis and the functional activities as the vertical axis. The matrix also has multiple overlays for generic issues. This might also be considered as a third orthogonal axis. 1.4 The terms used for the systems and components, functional, and overlay activities apply specifically to this matrix and are not intended to be universal. See Section 3. 1.5 Matrix Standards on Decommissioning of Nuclear Facilities (in preparation), Fuel Fabrication (in preparation), LWR Spent Fuel Receiving and Storage, and Nuclear Safeguards deal in detail with their respective subjects. Therefore, this standard will only refer to these standards and not develop the subjects. 1.6 This standard will be developed in two steps: (1) identifying a matrix of systems and component/functional/ overlay intersection where standards exist or are potentially needed and (2) completing the matrix by listing the existing standards and those potentially needed, assigning priorities to those needed and identifying potential secretariats. 1.7 While it is recognized that federal directives and guidelines are not national consensus standards, they may be included.

5.1 Knowledge of the olefinic, aromatic, and benzene content is very important in quality specifications of petroleum products, such as spark ignition fuels (gasoline) and hydrocarbon solvents. Fast and accurate determination of hydrocarbon types and benzene of petroleum distillates and products is also important in optimization of process units.5.2 This test method provides a fast standard procedure for determination of hydrocarbon types and benzene in light oxygenate-free petroleum distillates and products.1.1 This test method covers and provides for the quantitative determination of total saturates, total olefins, total aromatics and benzene in light petroleum distillates having a final boiling point below 215 °C by multidimensional gas chromatography. Each hydrocarbon grouping as well as benzene can be reported in both volume and mass percent.1.2 This test method is applicable to light petroleum distillates such as oxygenate-free motor gasoline or spark ignition fuels, naphthas and hydrocarbon solvents over the content ranges from 1 % (V/V) to 70 % (V/V) total olefins, 1 % (V/V) to 80 % (V/V) total aromatics and 0.2 % to 10 % (V/V) benzene. This test method may apply to concentrations outside these ranges, but the precision has not been determined. Interlaboratory testing for precision used full range blending streams, such as FCC, reformates and spark ignition fuel or blended motor gasolines.1.3 This test method is not intended to determine oxygenated components. Light petroleum distillate products such as motor gasoline may contain oxygenates. Oxygenates such as methyl tert-butyl ether (MTBE), tert-amyl methyl ether (TAME), ethyl tert-butyl ether (ETBE), ethanol and methanol etc. will coelute with specific hydrocarbon groups. If there is any suspicion the sample contains oxygenates, the absence of oxygenates should be confirmed by other standard test methods such as Test Methods D4815, D5599, or D6839 before using this test method.1.4 This test method is not applicable for the determination of individual hydrocarbon components with the exception of benzene. Test Method D6733 may be used to determine a large number of individual hydrocarbons to complement this test method.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

5.1 Lipid composition in a liposomal formulation is an important aspect during synthesis of liposomes, which determines stability, surface characteristics, drug encapsulation, and drug release capabilities. The cholesterol component plays a key role in controlled drug release by adding stability to the liposome. A small variation in the lipid composition can significantly alter the parameters mentioned above (15).5.2 Variation in the lipid composition in the liposomal formulation may influence the safety and efficacy of the product. Therefore, chemical composition of the liposomes shall be determined.5.3 The pharmaceutical industry and regulatory agencies require QC, QA, specifications, thorough characterization, and quantification of lipid components (16, 17).5.4 This test method can be used to ascertain variations in the lipid component profiling of various liposomal formulations. However, this test method does not intend to identify chemical degradation products (18).5.5 Analyzing the stability of analytes and their chemical degradation profiles as a result of oxidation or hydrolysis is beyond the scope of this test method (18, 19).1.1 This test method describes an analytical technique to quantify lipid components that are often present in liposomal formulations as major components.1.2 This test method uses high performance liquid chromatography (HPLC) to separate lipids in liposomal formulations and evaporative light-scattering detection (ELSD) to quantify the individual components.1.3 This test method quantifies three major organic components in liposomal formulations: cholesterol, 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG 2000), and hydrogenated soy L-α-phosphatidylcholine (HSPC).1.4 This test method can estimate the absolute concentration of cholesterol, DSPE-PEG 2000, and HSPC and their ratio (DSPE-PEG 2000: HSPC: cholesterol) in liposomal formulations.1.5 This test method describes preparation of calibration standards and samples, HPLC and ELSD instrumentation, method development and method validation, sample analysis, and data reporting.1.6 The detection limits and quantitation limits for the analytes (lipid components) in this test method are in the range of 2 µg/g to 4 µg/g and 7 µg/g to 10 μg/g, respectively. The analytical measurement ranges for cholesterol, DSPE-PEG 2000, and HSPC are 10 µg/g to 165 µg/g, 10 µg/g to 300 µg/g, and 10 µg/g to 200 µg/g, respectively.1.7 Significant digits and rounding of all reported values have been performed according to the guidelines as established in Practice D6026.1.8 Units—The values stated in SI units are to be regarded as the standard. Where appropriate, c.g.s units in addition to SI units are included in this standard.1.9 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.1.10 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 Gas chromatography with sulfur selective detection provides a rapid means to identify and quantify sulfur compounds in various petroleum feeds and products. Often these materials contain varying amounts and types of sulfur compounds. Many sulfur compounds are odorous, corrosive to equipment, and inhibit or destroy catalysts employed in downstream processing. The ability to speciate sulfur compounds in various petroleum liquids is useful in controlling sulfur compounds in finished products and is frequently more important than knowledge of the total sulfur content alone.1.1 This test method covers the determination of volatile sulfur-containing compounds in light petroleum liquids. This test method is applicable to distillates, gasoline motor fuels (including those containing oxygenates) and other petroleum liquids with a final boiling point of approximately 230 °C (450 °F) or lower at atmospheric pressure. The applicable concentration range will vary to some extent depending on the nature of the sample and the instrumentation used; however, in most cases, the test method is applicable to the determination of individual sulfur species at levels of 0.1 mg/kg to 100 mg/kg.1.2 The test method does not purport to identify all individual sulfur components. Detector response to sulfur is linear and essentially equimolar for all sulfur compounds within the scope (1.1) of this test method; thus both unidentified and known individual compounds are determined. However, many sulfur compounds, for example, hydrogen sulfide and mercaptans, are reactive and their concentration in samples may change during sampling and analysis. Coincidently, the total sulfur content of samples is estimated from the sum of the individual compounds determined; however, this test method is not the preferred method for determination of total sulfur.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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.

5.1 LWDs are intended to be used as a tool to ensure adequate compaction of unbound materials. Adequate soil compaction of infrastructure projects will provide load capacity, stability of the soil, decrease permeability, and prevent or reduce the settlement of supported pavements and structures. The target modulus or deflections are used to establish QA/QC acceptance criteria for the LWD tests in the field.5.2 This test method covers the determination of target acceptance modulus values of unbound materials based on measuring LWD deflections on laboratory proctor mold samples at varying moisture contents.5.3 This standard test method provides a target modulus calculation that accounts for the constrained conditions (in the compaction mold) of the test sample. The intent is to be able to compare the results from the laboratory samples to those of similar materials in the field at similar stress levels.55.4 The target modulus or deflections may be either correlated directly to pavement or structure performance or used to determine in situ material characteristics of the pavement or structure foundation layers.61.1 This test method describes the procedure to determine the target modulus (or deflection) required for compaction quality control of geomaterials using light weight deflectometer (LWD) drops on a compacted proctor mold in the laboratory.21.2 The same LWD type in terms of brand name, buffer stiffness, and deflection measurement location (on top of the plate or on top of the soil layer) used for the laboratory target modulus testing must be used during the field testing. This is to eliminate differences between measurements from different devices.1.3 This procedure shall be performed in the laboratory on representative soil samples before the field compaction operations.1.4 Gradation, moisture content inconsistency, and surface texture on the mold can affect the material moduli results.1.5 The target surface modulus values can be compared to the field-measured modulus for compaction quality control/quality assurance purposes.1.6 This test method covers the determination of the relationship between moisture content and modulus of unbound granular material using the light weight deflectometer (LWD) on laboratory compaction samples.1.7 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. The values given in parentheses are for information only.1.8 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.1.9 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.

The measurement of sulfur in the production and final product of gasoline and diesel is required for both regulatory purposes and to ensure maximum life expectancy of catalytic converters used in the automotive industry.1.1 This test method covers the determination of sulfur concentration in the range from 3.0 mg/kg to 1000 mg/kg in light liquid hydrocarbons and fuels with oxygenates boiling in the range from 26 °C to 274 °C (80 °F to 525 °F).NOTE 1: Preliminary data has shown that this test method is also applicable to the determination of sulfur in denatured fuel ethanol (Specification D4806), automotive spark ignition engine fuel (Specification D4814), Ed75–Ed85 (Specification D5798) or gasoline-oxygenate fuel blends with greater than 10 % ethanol. However, the precision for these materials has not been determined. Subcommittee D02.03 is undertaking activities to obtain precision statements for these materials.1.2 Other materials falling within the distillation range specified in 1.1, but having sulfur concentrations above 1000 mg/kg, may be tested using appropriate dilutions to bring them within the specified limit. In addition, sample types that may be outside the specified distillation range, such as diesels and biodiesels, may be analyzed by this test method.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. The preferred units are milligrams per kilogram (mg/kg).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.For specific hazard statements, see Sections 7 – 9.1.5 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.
