ASTM E2657-21 PDF

Scope: 1.1 This practice covers quantitative methods for the sampling and determination of bacterial endotoxin concentrations in water-miscible metalworking fluids (MWF). 1.2 Users of this practice need to be familiar with the handling of MWF. 1.3 This practice gives an estimate of the endotoxin concentration in the sampled MWF. 1.4 This practice replaces Method E2250. 1.5 This practice seeks to minimize interlaboratory variation of endotoxin data but does not ensure uniformity of results. 1.6 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. 1.7 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.
