1.1 These test methods cover the determination of the rate of evaporation of volatile liquids of low viscosity using the Shell Thin-Film Evaporometer. The test methods have been applied to a wide range of volatile liquids, including paint, varnish, and lacquer solvents and thinners to various hydrocarbons and to insecticide spray-base oils.

1.2 The test methods for the determination of evaporation rate using the thin-film evaporometer are:

Sections Method A 2.3 ---Manual Recording 5 to 11 Method B---Automatic Recording 12 to 17

1.3 The test methods are limited only by the viscosity of the volatile liquid which must be sufficiently low to permit the dispensing of an accurately measured specimen from a syringe.

1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
