1.1 本规程涵盖了从密封容器和最大容量为208-L的其他流体容器中对流体进行现场采样。它可用于制造、储存或使用水平，以获得用于化学、物理或颗粒物测定的代表性流体样品。 1.2 这种做法的使用取决于流体毒性、限制性流体气味、流体易燃性等变量。它适用于大多数液压油；然而，在使用前应小心确定兼容性。 2. 1.3 以国际单位制表示的数值应视为标准值。 本标准不包括其他计量单位。 1.4 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。 有关危险声明，请参阅 6.5.1 . 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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 使用本规程获得的样品旨在按照规程进行处理 F311 ，试验方法 D4898 ，以及试验方法 F314 ，以及其他化学或物理分析方法。

1.1 This practice covers field sampling of fluids from hermetically sealed containers and other fluid containers of 208-L volume maximum. It may be utilized at manufacturing, storage, or use levels for obtaining representative fluid samples for chemical, physical, or particulate matter determinations. 1.2 Use of this practice depends upon variables such as fluid toxicity, restrictive fluid odors, fluid flammability, and so forth. It is suitable for most hydraulic fluids; however, care should be exercised in determining compatibility before use. 2 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 hazard statement, see 6.5.1 . 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 ====== 4.1 Samples obtained by use of this practice are intended for processing in accordance with Practice F311 , Test Method D4898 , and Test Method F314 , and other chemical or physical methods of analysis.
