Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense. , as part of Federal Test Method Standard No. 175a.1

3、. Scope *1.1 This test method is suitable for measuring the fillercontent of phenol, resorcinol, and melamine resin-base adhe-sives mixed with hardener or catalyst, that set at room,intermediate, and high temperatures. Results are expressed onthe basis of the nonvolatile content of the mixed, liquid
