1.1本试验方法涵盖了使用生物动力学预测润滑剂生物降解性的程序。 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。 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。 ====意义和用途====== 该程序能够在一天内预测润滑剂的生物降解性，而无需处理微生物。 3. 试验结果与传统生物降解试验之间建立了良好的相关性（见试验方法D 5864 和试验方法D 6731 ).

1.1 This test method covers a procedure for predicting biodegradability of lubricants using a bio-kinetic. 1.2 the values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. ====== Significance And Use ====== This procedure is able to predict the biodegradability of lubricants within a day without dealing with microorganisms. 3 Excellent correlation is established between the test results and the conventional biodegradation tests (see Test Method D 5864 and Test Method D 6731 ).
