Exposure of adhesive specimens to high-energy radiation, 1973

The purpose of this recommended practice is to define conditions for the exposure of polymeric adhesives in bonded specimens to high-energy radiation prior to determination of radiation-induced changes in physical or chemical properties. The following kinds of radiation are covered: gamma or x-ray radiation, electron or beta radiation, neutrons, and mixtures of these such as reactor radiation. This practice specifies only the conditions or irradiation but does not cover the preparation of test specimens, testing conditions, or the evaluation of test. These are covered in the various ASTM methods or specifications for specific materials. Procedures are given for the following types of exposure: Procedure A - exposure at ambient conditions; Procedure B - exposure at controlled temperature; Procedure C - exposure in a medium other than air; Procedure D - exposure under load; and Procedure E - exposure combining two or more of the variables listed in Procedures A to D
