Standard Test Method for
Accelerated Aging of Adhesive Joints by the OxygenPressure Method1
This standard is issued under the fixed designation D 3632; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method describes how to estimate the relative
resistance to deterioration of adhesive films and adhesive-bonded joints placed in a high-pressure oxygen environment.
The instructions include both wood-to-wood and wood-to-metal joints as well as free film of adhesive. The effects of
chemicals such as fire retardants, preservatives, or wood
extractives can be evaluated by using materials containing
these chemicals for adherends.
1.2 This test method is primarily intended for elastomer-based construction adhesives but is also applicable to other
types of adhesives that may be susceptible to oxygen degradation. This accelerated test does not correlate exactly with the
natural ageing of the adhesive because of the varied conditions
of natural ageing and the absence of factors such as moisture
and stress. The results of this accelerated test are only
comparative and must be evaluated against the performance of
bonded joints whose natural and accelerated ageing characteristics are known.
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.
