Division 3.9.2 Failure to meet test requirements

In the event of failure to meet the test requirements, retesting or reheat treatment and retesting shall be carried out as follows:

1. (a)

   If there is evidence of a fault in carrying out a test, or an error of measurement, a further test shall be performed. If the result of this test is satisfactory, the first test shall be ignored;

2. (b)

   If the test has been carried out in a satisfactory manner, the cause of the test failure shall be identified.

If the failure is considered to be due to the heat treatment applied, the manufacturer may subject all the containers of that batch to a further heat treatment.

If the failure is not due to the heat treatment applied, all the identified defective containers shall be rejected or repaired by an approved method. The non-rejected containers shall then be considered as a new batch.

In both cases all the relevant prototype or batch tests needed to prove the acceptability of the new batch shall be repeated. If one or more tests prove even partially unsatisfactory, all containers of the batch shall be rejected.
