Common use of Relaxation provisions Clause in Contracts

Relaxation provisions. In the ambient temperature pressure cycling test in batch testing, finished cylinders shall be pressure cycled at a sampling frequency defined as follows: 9.3.2.3.1. One cylinder from each batch shall be pressure cycled with 11,000 cycles for the service life of 15 years. 9.3.2.3.2. On 10 sequential production batches of the same design, should none of the pressure cycled cylinders leak or rupture in less than 11,000 cycles x 1.5 for the service life of 15 years, then the pressure cycling test can be reduced to one cylinder from every 5 batches of production. 9.3.2.3.3. On 10 sequential production batches of the same design, should none of the pressure cycled cylinders leak or rupture in less than 11,000 cycles x 2.0 for the service life of 15 years, then the pressure cycling test can be reduced to one cylinder from every 10 batches of production. 9.3.2.3.4. Should more than 6 months have expired since the last batch of production, then the sampling frequency for the next batch of production shall be that specified in paragraph 9.3.2.3.2. or 9.3.2.3.3. above. 9.3.2.3.5. Should any cylinder tested at the sampling frequency in paragraph 9.3.2.3.2. or 9.3.2.3.3. above fail to meet the required number of pressure cycles, then it shall be necessary to repeat the pressure cycling test at the sampling frequency in paragraph 9.3.2.3.1 above for a minimum 10 production batches. The sampling frequency for testing thereafter shall be that specified in paragraph 9.3.2.3.2. or 9.3.2.3.3. above. 9.3.2.3.6. Should any cylinder tested at the sampling frequency in paragraph 9.3.2.3.1.,

On 10 sequential production batches of the same design, should none of the pressure cycled cylinders leak or rupture in less than 11,000 cycles x 2.0 for the service life of 15 years, then the pressure cycling test can be reduced to one cylinder from every 10 batches of production. 9.3.2.3.4. Should more than 6 months have expired since the last batch of production, then the sampling frequency for the next batch of production shall be that specified in paragraph 9.3.2.3.2. or 9.3.2.3.3. above. 9.3.2.3.5. Should any cylinder tested at the sampling frequency in paragraph 9.3.2.3.2. or 9.3.2.3.3. above fail to meet the required number of pressure cycles, then it shall be necessary to repeat the pressure cycling test at the sampling frequency in paragraph 9.3.2.3.1 above for a minimum 10 production batches. The sampling frequency for testing thereafter shall be that specified in paragraph 9.3.2.3.2. or 9.3.2.3.3. above. 9.3.2.3.6. Should any cylinder tested at the sampling frequency in paragraph 9.3.2.3.1.,, 9.3.2.3.2. or 9.3.2.3.3. above fail to meet the minimum requirement regarding the number of pressure cycles (11,000 cycles), then the cause of failure shall be determined and corrected following the procedures in paragraph 9.3.2.3.7. The pressure cycling test shall then be repeated on an additional three cylinders from that batch. Should any of the three additional cylinders fail to meet the minimum requirement regarding the number of pressure cycles (11,000 cycles), then all cylinders of this batch shall be rejected. 9.3.2.3.7. In the event of failure to meet test requirements retesting or reheat treatment and retesting shall be carried out as follows: (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; (b) If the test has been carried out in a satisfactory manner, the cause of test failure shall be identified. All cylinders that fail to meet the requirements shall be rejected or repaired by an approved method. The non-rejected cylinders are then considered as a new batch. In any case, the new batch shall be retested. All the relevant prototype or batch tests needed to prove the acceptability of the new batch shall be performed again. If any cylinder in a batch is proven unsatisfactory by one or more tests, all cylinders of this batch shall be rejected.
