Standard Practice for Storage Life of Adhesives by Viscosity and Bond Strength

SIGNIFICANCE AND USE
This practice is applicable to all adhesives having a relatively short storage life.
This practice is intended to determine whether the storage life conforms to the minimum specified storage life required of an adhesive by viscosity tests (Procedure A) or by bond strength tests (Procedure B), or by both. It does so by providing results before and after a set of standard conditions that simulate storage life. The determination of what the requirements for percentage of the original property retained or the minimum value for a property is found in the relevant material specification, or as agreed between manufacturer and user. PROCEDURE A—VISCOSITY TEST   Top
SCOPE
1.1 This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing.
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.
