This specification covers finished pellets composed of sintered gadolinium oxide-uranium dioxide of any concentration for use in light-water reactors. Materials shall adhere to specified chemical (impurity content, stoichiometry, moisture content, and gadolinium oxide concentration), nuclear (isotopic content), and physical (dimensions, density, homogeneity, integrity, axial and circumferential surface cracks, cylindrical surface chips, pellets ends, cleanliness and workmanship, identification, and irradiation stability) requirements.1.1 This specification is for finished sintered (U,Gd)O2 pellets. It applies to (U,Gd)O2 pellets containing uranium (U) of any 235U concentration and any concentration of gadolinium oxide (Gd2O3) for use in nuclear reactors.1.2 This specification recognizes the presence of reprocessed U in the fuel cycle and consequently defines isotopic limits for (U,Gd)O2 pellets made from commercial grade UO2. Such commercial grade UO2 is defined so that, regarding fuel design and manufacture, the product is essentially equivalent to that made from unirradiated U. UO2 falling outside these limits cannot necessarily be regarded as equivalent and may thus need special provisions at the fuel fabrication plant or in the fuel design.1.3 This specification does not include (a) provisions for preventing criticality accidents, (b) requirements for health and safety, (c) avoidance of hazards, or (d) shipping precautions and controls. Observance of this specification does not relieve the user of the obligation to be aware of and conform to all applicable international, federal, state, and local regulations pertaining to possessing, shipping, processing, or using source or special nuclear material. Examples of U.S. Governmental documents are Code of Federal Regulations (Latest Edition), Title 10, Part 50, Title 10, Part 70, Title 10, Part 71, and Title 49, Part 173.1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 The following precautionary caveat pertains only to the technical requirements portion, Section 4, of this specification: 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.

The component distribution of hydrocarbon liquid mixtures is often required as a specification analysis for these materials. Wide use of these hydrocarbon mixtures as chemical feedstocks or as fuel require precise compositional data to ensure uniform quality of the reaction product. In addition, custody transfer of these products is often made on the basis of component analyses of liquid mixtures.The component distribution data of hydrocarbon mixtures can be used to calculate physical properties, such as specific gravity, vapor pressure, molecular weight, and other important properties. Precision and accuracy of compositional data are extremely important when these data are used to calculate physical properties of these products.Note 3—Specifications for some hydrocarbon liquid mixtures, such as LPG, may be based on composition measured by Test Method . Nitrogen and carbon dioxide determinations are not within the scope of Test Method .1.1 This test method covers the analysis of demethanized liquid hydrocarbon streams containing nitrogen/air and carbon dioxide, and purity products, such as an ethane/propane mix that fall within the compositional ranges listed in Table 1. This test method is limited to mixtures containing less than 5 mol % of heptanes and heavier fractions.1.2 The heptanes and heavier fractions, when present in the sample, are analyzed by either (1) reverse flow of carrier gas after n-hexane and peak grouping or (2) precut column to elute heptanes and heavier first as a single peak. For purity mixes without heptanes and heavier, no reverse of carrier flow is required. (CautionIn the case of samples with a relatively large C6+ or C7+ fraction and where precise results are important, it is desirable to determine the molecular weight (or other pertinent physical properties) of these fractions. Since this test method makes no provision for determining physical properties, the physical properties needed can be determined by an extended analysis or agreed to by the contracting parties.)1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.Note 1—Annex A2 states values in manometric units, which are to be regarded as the standard in that section. Approximate SI units (from conversion) are given in parentheses.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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Low operating temperature fuel cells such as proton exchange membrane fuel cells (PEMFCs) require high purity hydrogen for maximum performance. The following are the reported effects (SAE TIR J2719) of the compounds determined by this test method.5.2 Carbon Dioxide (CO2), acts largely as a diluent; however, in the fuel cell environment, CO2 can be transformed into CO.5.3 Water (H2O), is an inert impurity, as it does not affect the function of a fuel cell stack; however, it provides a transport mechanism for water-soluble contaminants, such as Na+ or K+. In addition, it may form ice on valve internal surface at cold weather or react exothermally with metal hydride used as hydrogen fuel storage.5.4 Inert Gases (N2 and Ar), do not normally react with fuel cell components or fuel cell system and are considered diluents. Diluents can decrease fuel cell stack performance.5.5 Oxygen (O2), in low concentrations is considered an inert impurity, as it does not adversely affect the function of a fuel cell stack; however, it is a safety concern for vehicle on board fuel storage as it can react violently with hydrogen to generate water and heat.1.1 This test method describes a procedure primarily for the determination of carbon dioxide, argon, nitrogen, oxygen, and water in high pressure fuel cell grade hydrogen by gas chromatograph/mass spectrometer (GC/MS) with injection of sample at the same pressure as sample without pressure reduction, which is called “Jet Pulse Injection.” The procedures described in this method were designed to measure carbon dioxide at 0.5 micromole per mole (ppmv), Argon 1 ppmv, nitrogen 5 ppmv, oxygen 2 ppmv, and water 4 ppmv.1.2 Units—The values stated in SI units are to be regarded as standard.

5.1 Two procedures, A and B, are outlined in this test method. Procedure A is used most often for development of various beverage container designs to determine the functional characteristics of the package in regard to shelf life. Procedure B is recommended for use in beverage filling operations as a quality control tool in maintaining the desired CO2 fill pressure. A loss of CO2 will affect product taste.5.1.1 Procedure A involves the use of sensitive pressure and temperature monitoring equipment where a high degree of accuracy is essential, for example, a micro-pressure transducer and thermocouple for measuring pressure and temperature of the package in a closed system. Alternatively, this procedure may also use bottles closed with roll-on aluminum caps containing rubber septums. The septum is pierced with a hypodermic needle attached to a pressure transducer to obtain pressure readings. This procedure should be confined to laboratories that are practiced in this type of analytical testing.5.1.2 Procedure B is more widely used when measuring the carbonation level of the package due to the simplicity of the technique. A simple Manual pressure assembly or an Automated CO2 Analyzer is utilized.1.1 The objective of this test method is to determine the carbon dioxide (CO2) loss from plastic beverage containers after a specified period of storage time.1.2 Factors contributing to this pressure loss are volume expansion and the gas transport characteristics of the package, including permeation and leakage.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 These test methods are intended as a quick and reliable procedure for measuring the titanium dioxide pigment content of aqueous slurries. Included with the pigment content in the percent solids are the various nonvolatile additives used in preparing a stable slurry. Because the aluminum and silica oxide treatments on the more highly treated titanium dioxide pigments may change somewhat with prolonged drying, in the oven method the solids of the slurry are considered dry after heating at 105°C for 60 to 65 min. The high temperature associated with the infrared moisture analyzer may also effect a change in the aluminum and silica oxide treatment on highly treated TiO2 products. Therefore, care in selection of time and temperature are critical to obtain accurate results with the infrared method. With the short duration of test associated with the microwave drying system, overdrying is not a concern.1.1 These test methods cover the determination of the weight percent of solids in aqueous slurries of titanium dioxide pigments by either the use of a gravity-convection oven (Method A), infrared radiation moisture analyzer (Method B), or a microwave drying system (Method C).1.2 The values stated in SI units are to be regarded as standard.
