ASTM D4082-10

Standard Test Method for Effects of Gamma Radiation on Coatings for Use in Nuclear Power Plants

SIGNIFICANCE AND USE
This test method is designed to provide a uniform test to assess the suitability of coatings, used in nuclear power facilities, under radiation exposure for the life of the facilities, including radiation during a DBA (Coating Service Level I areas only). Specific plant radiation exposure may exceed or be less than the amount specified in 7.2 of this standard. If required by the licensee design basis, the gamma dose used may exceed the actual anticipated plant gamma dose to account for beta dose. Coatings in Level II and III areas (outside primary containment) are expected to be exposed to lower accumulated radiation doses.
SCOPE
1.1 This test method covers a standard procedure for evaluating the lifetime radiation tolerance of coatings to be used in nuclear power plants. This test method is applicable to Coating Service Levels I, II, and III.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

3.1Variations can occur in surface preparation, application, and curing of coating materials. They may affect the performance
of a coating system exposed to radiation when considered in conjunction with applicable engineered safety requirements.This test
method is designed to provide a uniform test to assess the suitability of coatings, used in nuclear power facilities, under continuous
radiation exposure for the projected 40-year lifetime of the facilities, including radiation during a DBA. Specific plant radiation
exposure may exceed or be less than the amount specified in 6.2 of this standard. The gamma dose used may exceed the actual
anticipated plant gamma dose in order to account for expected beta exposure as well. Coatings in Level II areas (outside primary
