11. Specimen Preparation
11.1 Tension Test:
11.1.1 Tension test specimens shall be taken from material in the final condition (temper) and tested in the direction of fabrication.
11.1.2 Whenever possible, all tubes shall be tested in full tubular size. When testing in full tubular size is not possible, longitudinal strip specimens, or the largest possible round specimen, shall be used. In the event of disagreement when full tubular testing is not possible, a longitudinal strip specimen with reduced gage length as contained in Test Methods E 8 shall be used.
11.1.3 In the case of stress-relieved tubes furnished with annealed ends, the tension test shall be made on the stress-relieved tubes prior to annealing the ends.
11.2 Hardness Test:
11.2.1 Stress-RelievedTubing with AnnealedEnds— The hardness test may be made on the inside of the tube near the end or on a specimen cut from the end, at the option of the manufacturer. The test shall be made on the inside of the specimen.
12. Test Methods
12.1 The chemical composition, mechanical, and other properties of the material as enumerated in this specification shall be determined, in case ofdisagreement, in accor- dance with the following methods:
12.2 The measurement of average grain size may be carried out by the planimetric method, the comparison method, or the intercept method described in Test Methods E112. Incaseofdispute the“referee” methodfordetermining average grain size shall be the planimetric method.
12.3 For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated below, in accordance with the rounding method of Practice E 29:
13. Inspection
13.1 Inspection ofthe material shall be made as agreed upon between the manufacturer and the purchaser as part of the purchase contract.
14. Rejection and Rehearing
14.1 Material not conforming to this specification or to authorized modifications will be subject to rejection.
14.2 Samples tested in accordance with this specifica- tion that represent rejected material shall be preserved for not less than three weeks from the date of the test report. In case of dissatisfaction with the results of the tests, the manufacturer may make claim for a rehearing within that time.
15. Certification
15.1 Amanufacturer’s certificationshallbefurnishedto the purchaser stating that material has been manufactured, tested, and inspected in accordance with this specification, and that the test results on representative samples meet specification requirements. A report ofthe test results shall be furnished.
16. Product Marking
16.1 Each bundle orshipping containershall be marked with the name of the material; condition (temper); this specification number; the size; gross, tare, and net weight; consignorandconsignee address; contractorordernumber; or such other information as may be defined in the contract or order.
