ASTM D7373-12 - 1.6.2012
 
Significance and Use

This procedure is able to predict the biodegradability of lubricants within a day without dealing with microorganisms. Excellent correlation is established between the test results and the conventional biodegradation tests (see Test Method D5864 and Test Method D6731).

 
1. Scope

1.1 This test method covers a procedure for predicting biodegradability of lubricants using a bio-kinetic model.

1.2 The values stated in SI units are to be regarded as 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.
