ASTM D2712-18 用气相色谱法测定次乙基中烃杂质的标准试验方法

5.1 High-purity propylene is required as a feedstock for various manufacturing processes, and the presence of trace amounts of certain hydrocarbon impurities may have adverse effects on yield or catalyst life. This test method is suitable for use as a benchmark in setting commercial specifications, for use as an internal quality control tool, and for use in development or research work. 1.1 This test method is used for the determination of hydrocarbon impurities in propylene (propene) material of 978201;% by mass or greater purity (concentrates). These impurities are determined in the concentration range of 0.358201;mg/kg to 8575 mg/kg and includes the following components: methane, ethane, ethylene, propane, acetylene, isobutane, propadiene, normal butane, trans-2-butene, butene-1, isobutylene, cis-2-butene, isopentane, methylacetylene, normal pentane, and 1,3-butadiene. Note 1: Optionally, the analysis may include the determination of pentenes/hexanes and heavier components, see 6.3. 1.2 This test method does not determine non-hydrocarbon impurities, and additional tests may be necessary to fully characterize the propylene sample. However, for the purposes of this test, the purity of propylene is determined as the difference between the total of the determined analytes and 1008201;% (by difference). 1.3 When this test method is being used for the determination of trace level impurities in high-purity propylene, the use of this test method for the analysis of propylene samples at lower purities is not recommended due to the potential for cross contamination between samples. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard may involve hazardous materials, operations, and equipment. 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.

1.1 This specification covers nitration grade xylene. 1.2 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard, an observed value or a calculated value shall be round off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the round-off method of Practice E29. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.4 Consult OSHA regulations, supplier’s Safety Data Sheets, and local regulations for all materials used in this specification. 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.

ASTM D2340-18 苯乙烯单体中过氧化物的标准试验方法

4.1 This test method is suitable for determining the quantity of peroxides in styrene monomer both for quality control and quality assurance of the product. 1.1 This test method covers the determination of the peroxide content of styrene monomer reported as hydrogen peroxide. 1.2 This test method has been found applicable to the determination of peroxides in styrene monomer in the range of 1 to 60 mg/kg. 1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29. 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 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 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.
