Historical Standard: ASTM E2657-09 Standard Test Method for Determination of Endotoxin Concentrations in Water-Miscible Metalworking Fluids
SUPERSEDED (see Active link, below)
ASTM E2657
1. Scope
1.1 This test method covers quantitative methods for the sampling and determination of bacterial endotoxin concentrations in water miscible metalworking fluids (MWF).
1.2 Users of this test method need to be familiar with the handling of MWF.
1.3 This test method gives an estimate of the endotoxin concentration in the sampled MWF.
1.4 This test method replaces E 2250.
1.5 This test method seeks to minimize inter-laboratory 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 and health practices and determine the applicability of regulatory limitations prior to use.
