ull-Off Strength of Coatings Using Portable Adhesion Testers,” (Ref. 32) provides guidance that the NRC staff finds acceptable for a test method used to evaluate the pull-off strength of coatings on metal substrates using fixed- alignment adhesion testers.2 4.5 ASTM D 5162-15, “Standard Practice for Discontinuity (Holiday) Testing of Nonconductive Protective Coating on Metallic Substrates,” (Ref. 33) offers guidance that the NRC staff finds acceptable for determining discontinuities using low voltage wet sponge and high voltage spark testers. 4.6 ASTM D 6677-07 (reapproved 2012), “Standard Test Method for Evaluating Adhesion by Knife,” (Ref. 34) provides guidance that the NRC staff finds acceptable for a test method used to evaluate adhesion using a knife. 4.8 ASTM D 7091-13, “Standard Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Non-Ferrous Metals,” (Ref. 35) provides guidance that the NRC staff finds acceptable for using magnetic and eddy current gages to obtain coating dry film thickness measurements. 2 A fixed-alignment adhesion Tester Type II (Test Method B) is the test method that NPPs have historically used. DG-1331, Page 12 4.9 ASTM D 7234-12, “Standard Test Method for Pull-Off Adhesion Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers” (Ref. 36), provides guidance that the NRC staff finds acceptable for a test method used to evaluate the pull-off strength of coatings on concrete using portable pull-off adhesion testers. 4.10 ASTM D 7491-08,(reapproved 2015) “Standard Guide for Management of Non-Conforming Coatings in Coating Service Level I Areas of Nuclear Power Plants,” (Ref. 37) offers guidance that the NRC staff finds acceptable for managing nonconforming coatings within the Service Level I areas of a NPP. 5.0 Additional Information 5.1 Electric Power Research Institute (EPRI) Report No.
