Standard Test Method for Determining Corrosivity of Adhesive Materials

SCOPE
1.1 This test method is intended to determine whether an adhesive material, cured or uncured, is corrosive to a metal. It is a general test method intended to screen out those materials that give a visible sign of corrosion.  
1.2 This standard does not purport to address all of the safety problems, 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.
