Description

This European standard describes non-destructive examination procedures and test piece types necessary to perform the tests on brazed joints.

The non-destructive examination methods described are as follows:

1. visual examination (see clause 4);
2. ultrasonic examination (see clause 5);
3. radiographic examination (see clause 6);
4. penetrant examination (see clause 7);
5. leak testing (see clause 8);
6. proof testing (see clause 9);
7. thermography (see clause 10).

The brazed joints to which these tests are applied can either be test samples manufactured to obtain brazed joint design data, or manufactured as part of the approval testing of a brazing procedure, or parts of a brazed assembly.

The type of test piece described for each test can be quoted or incorporated in engineering application standards that deal with brazed assemblies.
