Quantifying Adenosine Triphosphate (ATP) in Water-miscible Metalworking Fluids - ASTM E 2694 Interlaboratory Study to Determine Test Method’s Precision

摘要

An integral component of the ASTM process for new standard test methods is to perform an interlaboratory study (ILS). In January 2011, ten companies participated in an ILS for ASTM E 2694 Method for Measurement of Adenosine Triphosphate in Water-Miscible Metalworking Fluids. The ILS included samples of emulsifiable oil, semi-synthetic and synthetic metalworking fluid formulations with ATP bioburdens ranging from 0.3 Log10 pg ATP mL-1 to >5.0 Log 10 pg ATP mL-1. This presentation discusses the ILS test plan design and results.
