1.1本试验方法包括通过过滤交付至实验室的航空涡轮燃料样品中的颗粒污染物进行重量测定。 1.1.1使用真空通过测试膜和对照膜过滤样品。质量变化差异确定了单位体积的污染物水平。 1.2以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 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和健康实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅4.2、7.3、7.5、11.3和X1.7.2。在使用本标准之前，请参阅供应商的安全标签、材料安全数据表和技术文献。

1.1 This test method covers the gravimetric determination by filtration of particulate contaminant in a sample of aviation turbine fuel delivered to a laboratory. 1.1.1 The sample is filtered through a test membrane and a control membrane using vacuum. The mass change difference identifies the contaminant level per unit volume. 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. For specific hazard statements, see 4.2, 7.3, 7.5, 11.3 and X1.7.2. Before using this standard, refer to supplier's safety labels, material safety data sheets, and technical literature.
