Description:
Significance and Use
2.1 These test methods are applicable to varnish and are useful to producers and users in determining nonvolatile content and are sometimes an appropriate measure of the film-forming matter in varnish.
Scope
1.1 These test methods determine the fraction of a varnish that is nonvolatile at the temperature of the test while volatile solvents are driven off. It is sometimes an approximate measure of the film-forming matter in a varnish.
