Standard Test Method for Metalworking Fluid Aerosol in Workplace Atmospheres

Abstract

5.1 This test method covers the gravimetric measurement4 of metal removal fluid aerosol concentrations in workplace atmospheres. 5.2 This test method provides total particulate matter concentrations for comparison with historical exposure databases collected with the same technology. 5.3 This test method provides an extension to current non-standardized methods by adding an extractable mass concentration which reduces interferences from nonmetal removal fluid aerosols. 5.4 This test method does not address differences between metal removal fluid types, but it does include extraction with a broad spectrum of solvent polarity to adequately remove many of the current fluid formulations from insoluble background aerosol.5 5.5 This test method does not identify or quantify any specific putative toxins in the workplace that can be related to metal removal fluid aerosols or vapors. 5.6 This test method does not address the loss of semivolatile compounds from the filter during or after collection.
