1.1 These test methods cover the determination of the resistance of adhesives to cyclic accelerated service conditions by exposing bonded specimens to conditions of high and low temperatures and high and low relative humilities. The extent of degradation is determined from changes in strength properties as a result of exposure to the test conditions (Note 1). It is recognized that no accelerated procedure for degrading materials correlates perfectly with actual service conditions, and that no single or small group of laboratory test conditions will simulate all actual service conditions. Consequently, care must be exercised in the interpretation and use of data obtained in this test method. The test procedure, the number of cycles of the test procedure to be used, the particular strength property to be used to determine the extent of degradation, and whether test specimens or test panels are to be used, shall be specified in the material specification.

Note 1-These test methods are intended for use with specimens described in the approved ASTM strength test methods for adhesives as follows: Test Methods D 897, D 903, D 906, D 950, D 1002, D 1062, and Method D 1344.
