ASTM D1338-99(2016)

Standard Practice for Working Life of Liquid or Paste Adhesives by Consistency and Bond Strength

SIGNIFICANCE AND USE
4.1 To determine acceptable working life of an adhesive, two procedures are used. This practice is intended to apply to:  
4.1.1 Self-contained liquid or paste adhesives,  
4.1.2 Adhesives requiring addition of a catalyst, hardener, filler, thinner, and so forth, or combinations of two or more of these materials just prior to use, and  
4.1.3 Powdered or flaked adhesives which are dissolved in water or other solvent and are used as liquid or paste adhesives.
SCOPE
1.1 This practice covers two procedures applicable to all adhesives having a relatively short working life. It is intended to determine whether the working life conforms to the minimum specified working life of an adhesive required by consistency tests or by bond strength tests, or by both.  
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.
