Non-destructive testing -- Penetrant testing -- Part 3: Reference test blocks
This European standard describes two types of reference blocks:
- Type 1 reference blocks are used to determine the sensitivity levels of both fluorescent and colour contrast penetrant product families;
- Type 2 reference blocks are used for routine assessment of the performance of both fluorescent and colour contrast penetrant facilities and part-used containers.
The reference blocks are used in the same conditions as the pieces to be tested according to EN 571-1.
