Scope and object

An important object of this part of the standard is to specify the controls which shall be maintained over the exposure conditions during and after the irradiation of insulating materials with ionizing radiation prior to the determination of radiation-induced changes in physical or chemical properties. A number of potentially significant irradiation conditions are discussed and various parameters which can influence the radiation-induced reactions under these conditions are specified. The objective is to emphasize the importance of selecting suitable specimens, exposure conditions and test methods for determining the effect of radiation on appropriately chosen properties. Since many materials are used either in air or in inert environments, standard exposure conditions are recommended for both of these situations. Example test reports for a number of materials are also included in appendix A of this standard.

It should be noted that the scope of this standard does not consider measurements which are performed during the irradiation.
