Data Supporting a Provisional American Society for Testing and Materials (ASTM) method for Metalworking Fluids, Part I: A Solvent Blend with Wide-Ranging Ability to Dissolve Metalworking Fluids

摘要

Data are presented to support modification to a provisonal American Society for Testing and Materials (ASTM) sampling and analytical technique for metalworking fluids (ASTM P-42-97). The method, tentatively recommended by ASTM Subcommittee D-22.04, involves collection of the aeroscolized fluid on a filter and spearation of the fluid from co-sampled particulate matter via solvent extraction of that fluid from co-sampled particulate matter via solvent extraction of that fluid from the filter. The solubilities of nine metalowrking fluids were tested in seven solvents: acetone, dichloromethane, ethyl acetate, isopropanol, methanol, toluene, water, and three solvent blends: dichloromethane: methanol, dichlormethane: methanol:toluene, and dichloromethane:methanol:hexane. A ternary blend of dichloromethane:methanol:toluene(1:1:1) was found to dissolve samples of the four classes of metalworking fluids within about 1 min.
