Standard Test Method for Determining Corrosivity of Adhesive Materials

SIGNIFICANCE AND USE
This test method is a subjective test in that determinations of degree of corrosivity is based upon a visual inspection for a green discoloration or other evidence of corrosion.
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 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
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.
