4.1 It is possible to modify the properties of phenol, resorcinol, and melamine-based adhesives by adding fillers to the adhesive and in doing so affect the way the adhesive performs. This test method makes possible accurate determination of these filler levels for purposes of quality control and characterization of the adhesive.

1.1 This test method is suitable for measuring the filler content of phenol, resorcinol, and melamine resin-base adhesives mixed with hardener or catalyst, that set at room, intermediate, and high temperatures. Results are expressed on the basis of the nonvolatile content of the mixed, liquid adhesive.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, 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.
