Standard Test Method for Hydrogen Ion Concentration of Dry Adhesive Films

SIGNIFICANCE AND USE
5.1 The pH of an adhesive may be a factor whereby the adherends or the adhesive itself may be adversely affected in time by the acidity or alkalinity.
SCOPE
1.1 This test method covers determination of the hydrogen ion concentration (pH), acidity, or alkalinity, of organic adhesives in the cured dry film form. This test method is not designed to apply to pressure-sensitive adhesives.  
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.
