15. Number of Tests
15.1 Except as required by 15.2, oflC of each of the tests specified in Section 7, 8.2, and Section 9 shall be made on test specimens taken from one length of pipe from each lot of each pipe size. For continuous-welded pipe, a lot shall contain no more than 25 tons 123 Mg o pipe for pipe sizes NPS I II)N 401 and smaller, and no more than 50 tons 145 Mgi of pipe for pipe sizes NPS 2 IDN 50J and larger. For seamless and clectric-resistancewelded pipe. a lot shall contain no more than one heat. and at the option of the manufacturer shall contain no more than 500 lengths of pipe (as initially cut after the final pipe-forming operation, prior to any further cutting to the required ordered lengths) or 50 tons 145 MgI of pipe.
15.2 The number of flattening tests for electric-resistance-welded pipe shall be in accordance with 9.3.1 or9.3.2. whichever is applicable.
15.3 Except as allowed by 11.2. each length of pipe shall be subjected to the hydrostatic lest specified in Section 10.
16. Retest.s
16.1 If the results of the mechanical lcsts of any lot do not confnn to the requirements specified in Sections 7. 8. and 9. retests are permitted to he made on additional pipe of double the original number from the same lot, each of which shall confonn to the requirements specified.
16.2 For pipe produced in single lengths, if any section of the pipe fails to comply with the requirements of 9.3. it shall be permissible to cut other secliotis froni the same end of the same length until satisfactory tests are obtained, except that the finished pipe shall not be shorter than XO* of its length after the onginal cropping; otherwise the length shall be rejected. For pipe produced in multiple lengths. it shall be permissible to cut retests front each end of each individual length in the multiple. Such tests shall be made with the weld alternately O and 90O from the line of direction of force.
17. Test Methods
17.1 The test specimens and the tests required by this specification shall conform to those described in the latest issue of Test Methods and Definitions A 370.
17.2 The longitudinal tension test specimen shall be taken from the end of the pipe or. for continuous-welded pipe, it shall be permissible to be taken from the skelp.
23.1.2 Specification number (year of issue not required).
NOTE 9 — Pipe ihat comphes with inuk,pte compatible speciticahion may be marked with the approprilMe dcsigninon for eh specification.
23.1.3 Sue (PS and weight class, schedule number. or nominal wall thickness: or specified ouside diameter and nominal wall thickness),
23.1.4 Grade (A or B).
23.1.5 Type of pipe (F. Ii, or S).
23J.6 Test pressure. seamless pipe only (if applicable. in accordance with Table 4),
23.1.7 Nondestruciive electric test, seamless pipe only (if applicable, in accordance with Table 4),
23.2 Unless another marking fonnat is specified in the purchase order, length shall be marked in feet and tenths of a foot, or metres to two decimal places. dependent upon the units to which the pipe was ordered. The location of such marking shall he at the option of the manufacturer.
23.3 Ileat number, lot number, run number, or a combination thereof shall be marked at the option of the mnanufacturer, unless specific marking is specified in the purchase order. 11w location of such marking shall he at the option of the manufacturer.
23.4 An’ additional information desired by the nianufacturer or specified in the purchase order.
23.5 For pipe NPS l Il)N 401 and smaller that is bundled, it shall be permissible to mark this information on a tag securely attached to each bundle.
23.6 When pipe sections are cut into shorter lengths by a subsequent producer for resale as material, the processor shall transfer complete identification including the name or brand of the manufacturer, to each unmarked cut length. or to metal tags securely attached to unmarked pipe bundled in accordance with the requirements of 23.5. The same material designation shall be included with the inlrmation transferred, and the processor’s name. trademark. or brand shall he added.
23.7 Bar Coding — In addition to the requirements in
23.1, 23.5. and 23.6. bar coding is accepable as a supplementary identification method. It is recommended that bar coding be consistent with the Automotive Industry Action Group (AIAG) standard prepared by the Primary Metals Subcommittee of the AIAG Bar Code Project Team.
24.1 When specified in the contract. material shall he preserved. packaged. and packed in accordance with the requirements of MIL-STD-163.
