ASTM D1353 Nonvolatile Matter in Volatile Solvents for Use in Paint, Varnish, Lacquer, and Related Products
Degreasers and spray lubricants often contain volatile solvents that evaporate after product delivery to leave the treated surface coated with the intended product. If the solvent contains nonvolatile matter such as additives, contaminants or degradation products, solvent residue may remain after evaporation potentially changing product attributes. This method determines the amount of nonvolatile residue in volatile solvents.
The sample is placed in an evaporating dish, heated, cooled and weighed. The heating/cooling/weighing cycle is repeated until a constant weight is obtained. The nonvolatile residue per 100 ml sample is reported.
