Historical Standard: ASTM E2564-11 Standard Test Method for Enumeration of Mycobacteria in Metalworking Fluids by Direct Microscopic Counting (DMC) Method
SUPERSEDED (see Active link, below)
ASTM E2564
1. Scope
1.1 This test method describes a direct microscopic counting method (DMC) for the enumeration of the acid fast stained mycobacteria population in metalworking fluids. It can be used to detect levels of total mycobacteria population, including culturable as well as non-culturable (possibly dead or moribund ) bacterial cells. This test method is recommended for all water-based metalworking fluids.
1.2 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. For additional safety information, see Laboratory Safety: Principle and Practices, 4th Edition
