ASTM E525-90(1996)

1.1 This practice covers procedures for determining and reporting the neutron fluence rate and fluence for the correlation of radiation-induced changes in nuclear graphites.

1.2 The purpose of this practice is to achieve better correlation and interpretation of new data in the field of radiation effects testing of specimens of graphites to be used for moderator or reflector components of fission reactors.

1.3 Excluded from this practice are graphite test specimens containing fissionable materials and specimens containing materials having high neutron cross sections.
