Data are presented to support modification to a provisional 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 aerosolized fluid on a filter and separation of the fluid from co-sampled particulate matter via solvent extraction of that fluid from the filter. The solubilities of nine metalworking fluids were tested in seven solvents: acetone, dichloromethane, ethyl acetate, isopropanol, methanol, toluene, water, and three solvent blends: dichloromethane: methanol, dichloromethane:methanol:toluene, and dichloro-methane: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.
