Standard Test Method for Determination of Chemical Species in Marine Fuel Oil by Multidimensional Gas Chromatography/Mass Spectrometry 通过多维气相色谱/质谱法测定海洋燃料油中化学物质的标准测试方法
发布日期: 2020-06-15
1.1 本试验方法包括通过气相色谱/质谱法定量测定船用燃料油(船用燃料油)中的各种化学物质。通过使用相同的条件并选择所需的质谱选择离子,该试验方法可用于测定除已建立精度声明和检测限的物种以外的其他物种。 1.2 通过本试验方法确定量化极限的化学物种示例列表如所示 表1 . 1.3 其他炼油厂烃馏分及其混合物可使用相同的试验方法条件进行试验。然而,该测试方法的精度反映了 表1 . 1.4 结果报告精确到1.0 毫克/千克。 1.5 以国际单位制表示的数值应视为标准值。 1.5.1 例外情况- 非SI值为psig。 1.6 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 该试验方法允许在海洋燃料油和刀具库存中定量低水平的化学物质。在海洋燃料油中发现了许多类型和浓度的化学物质。 燃料中此类物质的存在或其浓度与据称由使用这些燃料引起的任何故障模式之间的根本原因关系尚未确定。本试验方法对于建立未来ISO 8217:2010所需的试验条件是必要的,如第5.5节和附录B第(d)项所定义。可通过使用相同的条件并相应地选择所需的质谱选择离子来确定其他化合物。
1.1 This test method covers the quantitative determination of a variety of chemical species in marine fuel oil (bunker fuel oil) by gas chromatography/mass spectrometry. By using the same conditions and by selecting required mass spectral selected ions, the test method may be used for the determination of other species than those for which precision statements and limits of detection have been established. 1.2 An example list of chemical species for which a limit of quantification has been determined by means of this test method is given in Table 1 . 1.3 Other refinery hydrocarbon fractions and their mixtures may be tested using the same test method conditions. However, the precision of this test method reflects the compounds in Table 1 . 1.4 Results are reported to the nearest 1.0 mg/kg. 1.5 The values stated in SI units are to be regarded as standard. 1.5.1 Exception— Non-SI values are given for psig. 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. ====== Significance And Use ====== 5.1 The test method allows the quantitation of chemical species at low levels in marine fuel oils and cutter stocks. A great many types and concentrations of chemical species are found in marine fuel oils. A root cause relationship between the presence of such species or their concentration in fuels and any failure modes allegedly induced by the use of these fuels has not been established. This test method is necessary to establish test conditions required for future ISO 8217:2010 as defined in section 5.5 and Annex B item (d). Additional compounds may be determined by using the same conditions and by selecting required mass spectral selected ions, accordingly.
