Scope
This standard stipulates that at the test temperature, the solvent evaporates, the non-volatile content of the varnish is measured at a reduced amount, and the amount of the non-volatile content of the varnish forming a film is estimated. Note 1: Caution – Since the flash temperature of most solvents used in coatings and related products is lower than the test temperature, care should be taken not to exceed the minimum explosion limit of the solvent. The amount of solvent under the oven pressure at any time depends on the number of test dishes in the oven, the non-volatile percentage of the sample, the oven
