1.1本试验方法包括在实验室条件下测定完全配制的润滑剂或其成分暴露于接种物时的需氧水生生物降解程度。 1.2本试验方法旨在专门解决与测试水不溶性材料和复杂混合物（如许多润滑剂中发现的）相关的困难。 1.3本试验方法适用于所有不易挥发且在试验浓度下对接种物中存在的生物体无抑制作用的润滑剂。 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和健康实践，并确定监管限制的适用性。 第10节讨论了具体危险。

1.1 This test method covers the determination of the degree of aerobic aquatic biodegradation of fully formulated lubricants or their components on exposure to an inoculum under laboratory conditions. 1.2 This test method is intended to specifically address the difficulties associated with testing water insoluble materials and complex mixtures such as are found in many lubricants. 1.3 This test method is designed to be applicable to all lubricants that are not volatile and are not inhibitory at the test concentration to the organisms present in the inoculum. 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards are discussed in Section 10.
