1.1 这些测试方法涵盖了有和没有静电耗散添加剂的航空燃料和馏分燃料的电导率的测定。测试方法通常给出燃料未充电时的电导率的测量值，即电静止时的电导率（称为静止电导率）。 1.2 有三种测试方法可用于燃料电导率的现场测试。这些是:（。 1 )用于在罐中直接测量或燃料样品的现场或实验室测量的便携式仪表，( 2 )在线/侧流采样仪，用于直接对从管道到回流或废物的燃料进行采样，以及( 3 )用于直接在燃料分配管道系统中连续测量燃料电导率的在线仪表。在使用便携式仪表时，必须注意在测量前允许残余电荷松弛，并防止燃料污染。1.3 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 具体的注意事项，请参见 7.1 , 7.1.1 ，和 11.2.1 . 1.5 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》中确立的国际公认的标准化原则制定的。======意义和用途====== 5.1 燃料消散在泵送和过滤操作期间产生的电荷的能力由其电导率控制，电导率取决于其离子物质的含量。如果电导率足够高，电荷消散得足够快以防止其积累，并且避免了接收槽中危险的高电位。

1.1 These test methods cover the determination of the electrical conductivity of aviation and distillate fuels with and without a static dissipator additive. The test methods normally give a measurement of the conductivity when the fuel is uncharged, that is, electrically at rest (known as the rest conductivity). 1.2 Three test methods are available for field tests of fuel conductivity. These are: ( 1 ) portable meters for the direct measurement in tanks or the field or laboratory measurement of fuel samples, ( 2 ) on-line/side stream sampling meters for direct sampling of fuel from a pipeline to either a return or to waste, and ( 3 ) in-line meters for the continuous measurement of fuel conductivities directly in a fuel distribution pipeline system. In using portable meters, care must be taken in allowing the relaxation of residual electrical charges before measurement and in preventing fuel contamination. 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. 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 precautionary statements, see 7.1 , 7.1.1 , and 11.2.1 . 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. ====== Significance And Use ====== 5.1 The ability of a fuel to dissipate charge that has been generated during pumping and filtering operations is controlled by its electrical conductivity, which depends upon its content of ion species. If the conductivity is sufficiently high, charges dissipate fast enough to prevent their accumulation and dangerously high potentials in a receiving tank are avoided.
