scope:

This Standard describes three types of reference blocks to be used for JIS Z 2343-1 and JIS Z 2343-2: Type 1 reference blocks are used to determine the sensitivity levels of both fluorescent and colour contrast penetrant product families; Type 2 and Type 3 reference blocks are used for routine assessment of the performance of both fluorescent and colour contrast penetrant facilities, and in-use penetrant. The reference blocks are used in the same conditions as those of test panels according to JIS Z2343-1 and JIS Z2343-2.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are follows. ISO 3452-3:2013 Non-destructive testing - Penetrant testing - Part 3: Reference test blocks (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1
