Doplňujúce informácie

1. Scope

1.1 The purpose of this 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. This recommended practice specifically covers the following kinds of radiation: gamma or X-ray radiation, electron or beta radiation, neutrons, and mixtures of these such as reactor radiation.

1.2 This practice specifies only the conditions of 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.

1.3 This practice covers procedures for the following five 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. Procedure E- Exposure combining two or more of the variables listed in Procedures A to D.

Note 1-The problems of measuring the properties of materials during irradiation involve shielding and remote control facilities and are, therefore, not considered in this practice.
