8 Re-tests
If any test fails to comply with the requirements of this International Standard, the brazer or brazing operator shall be given the opportunity to repeat the qualification test once without further training.
If it is established that failure is due to metallurgical or other extraneous causes that cannot be directly attributed to the lack of skill of the brazer or brazing operator, an additional test is required in order to assess the quality and integrity of the new test material and/or new test conditions.
9 Period of validity
9.1 Initial qualification
The period of validity of the brazer qualification starts at the date of brazing, or the date of prolongation, see 9.2. However, the brazer qualification is not valid until all required tests are completed and accepted.

b) The work of the brazer or brazing operator shall be in general accordance with the technical conditions under which the qualification test is carried out.
c) There shall be no specific reason to question the skill and knowledge of the brazer or brazing operator (if applicable).

The examiner or examining body shall verify compliance with conditions a) and b). and sign or issue the prolongation of the qualification test certificate for the brazer.
10 Certificate
A certificate shall be issued to detail that the brazer or brazing operator has passed the performance qualification test. The relevant test conditions shall be recorded on the certificate.
If the brazer or brazing operator fails any of the prescribed tests, no certificate shall be issued.
The certificate shall be issued under the sole responsibility of the examiner or examining body. The brazer qualification certificate shall contain all the information specified in Annex A. The brazing operator qualification certificate, issued when mechanized brazing is tested, shall contain all the information specified in Annex B.
