An important object of this part of the standard is to specify the controls which shall be main-
tained 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.
