1、Designation: D1582 98 (Reapproved 2017)Standard Test Method forNonvolatile Content of Liquid Phenol, Resorcinol, andMelamine Adhesives1This standard is issued under the fixed designation D1582; the number immediately following the designation indicates the year oforiginal adoption or, in the case of

2、 revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of nonvolatilecontent or total solids of liquid pheno

3、l, resorcinol, andmelamine adhesives with or without hardener (Note 1) addedand containing high-boiling and low-boiling volatile organicsolvents or water, or both.NOTE 1Some low molecular weight materials in the adhesive may belost if hardener is not used. When a hardener is used, it must be mixed i

Summary of Test Method4.1 Without HardenerA weighed amount of adhesive andquartz sand are oven-dried, cooled in a desiccator, andweighed. The percent nonvolatile content is calculated basedon the am

8、ount remaining.4.2 With HardenerA weighed amount of mixed adhesiveis oven dried, cooled in a desiccator, and weighed. The percentnonvolatile content is calculated based on the amount remain-ing.5.

9、 tempera-tures of 70 6 1C, 105 6 1C, and 150 6 1C. (Warning Asafety (explosion-proof) oven should be used when volatilematerials are likely to burn or explode.)5.3 Desiccator, with drying agent and tray.5.4 Analytical Balance, accurate to 1 mg.6. Sampling6.1 Except in special cases, take a composite

10、 sample fromthree or more separate containers chosen at random. Also, takesamples from containers which appear to be nonrepresentativeand test such samples separately. Place the samples immedi-ately in airtight containers, filled to prevent excessive air spaceabove the adhesive, and take precautions
