2. Unsatisfactory tensile test specimens (excluding pipes) 2.1 Individual tests For each unsatisfactory tensile specimen, two substitute specimens shall be tested, which shall be taken from the same test section as the original specimen, or from the same sample. In every case, both specimens shall satisfy the requirements. 2.2 Testing by heats or batches The manufacturer shall have the option of separating the sample which has yielded unsatisfactory results or of continuing to treat it as part of the unit test quantity. If the sample in question is separated, then, for each unsatisfactory tensile specimen, two substitute specimens shall be tested which shall be taken from different samples of the unit test quantity. If the sample in question continues to be treated as part of the unit test quantity, one of the retests shall be performed on this sample and the other on a different sample. Both retests shall satisfy the requirements. 3. Unsatisfactory impact test specimens (excluding pipes) 3.1 Individual tests If the average value of 3 impact test specimens fails to satisfy the requirements or if a single value is less than 70 % of the stipulated average value, 3 substitute specimens shall be taken from the same test section and tested. The average value of the 6 individual tests shall then meet the requirements. However, of the 6 individual values only 2 may be below the required average value, of which only one individual value may be less than 70 % of the prescribed average value, failing which the sample in question shall be rejected. 3.2 Testing by heats or batches If the average value of 3 impact test specimens fails to satisfy the requirements or if a single value is less than 70 % of the stipulated average value, then the procedure described in 3.1 shall be applied initially. If the retest also produces an unsatisfactory result, the sample tested shall be rejected and two further samples, of the same or the next smaller thickness, from the same unit test quantity shall be tested. If, again, one of the samples fails to satisfy the requirements, then the entire unit test quantity shall be rejected. With the consent of the Surveyor, the remaining sample quantities in the unit test quantity may, however, be subjected to testing piece by piece. 4. Unsatisfactory drop weight test specimens 4.1 Individual tests If one or both of the two test specimens fail(s), two similar substitute specimens may be taken from the same sample and tested. Both substitute specimens shall satisfy the requirements. If they fail to do so, the relevant sample shall be rejected. 4.2 Testing by heats If one or both of the two test specimens to be taken from the thickest sample of the heat fail(s), then, from the same sample and from a different sample of the same thickness - or, if not available, from the next smaller thickness - two specimens of the same type each shall be taken and tested. All four specimens shall satisfy the requirements. If they fail to do so, then the relevant heat shall be rejected. With the consent of the Surveyor, the remaining sample quantities in the rejected heat may, however, be subjected to individual testing. 5. Unsatisfactory results in the testing of pipes 5.1 Testing by batches If, when subjected to the tensile test, the ring test or the notched bar impact test, pipes fail to satisfy the requirements, the test which has produced the unsatisfactory results shall be repeated on the same end of the pipe selected for the test. If the new test fails to satisfy the requirements, the pipe in question shall be discarded. In its place two further pipes shall be taken from the batch concerned and shall be subjected to the full range of tests. If, during testing, one of the requirements is not met, then the entire batch shall be deemed unacceptable. However, with the consent of the Surveyor, the characteristic which failed to meet the requirements may be checked on each individual pipe. 6. Retesting specified in standards Where a national or international standard specifies a wider scope for the performance of repeat tests; this shall take precedence over the retests described in 5.1. |
