5.1.2.4 Refrree Test — In the event that the chemical analysis of columbiurn or vanadium does not meet the requirements of 5,1.2.2, the grain size test shown in 5.1.2 shall be the referee test unless an alternative test method is agreed upon between the manufacturer and the purchaser.
6. Mechanical Property Requirements
6.1 Te.it Specinaen.c:
6.1.1 Selection — Test specimens shall he selected in accordance with the requirements of the applicable product specification or in accordancc with Supplement I of the latest issue of Test Methods and Dclinitions A 370, in the sequence named.
6.1.2 Prepiration — Unless otherwise specified in he applicable product specification, test specimens shall be prepared in accordance with the latest issue of Test Methods and Definitions A 370. and especially Supplement I thereof.
6.2 Methods of Mechanical Testing — All mechanical tests shall be conducted in accordance with the latest issue of Test Methods and Definitions A 370. and especially Supplement I thereof, on steel bar products.
6.3 Revests:
6.3.1 If any test specimen shows defective machining or develops flaws, the specimen may be discarded and another substituted.
6.3.2 If the percentage elongation of any tension specimen is less than that specified and any part of the fracture is more than in. 120 mmj from the center of a 2 in. 150 mmj specimen. or is outside the middle half of the gage length of an 8 in. 1200 mml specimen as indicated by scribe scratches marked on the specimen before testing. a retest shall be allowed.
6.3.3 For “as-wrought” material, lithe results for any original tension specimen are within 2000 psi 114 MPaJ of the required tensile strength. within 1000 psi [7 MPa] of the required yield point, or within 2% of the required elongation, relesting shall be permitted. If the original testing required only one test, the retest shall consist of two random tests from the heat or lot involved. If the original testing required two tests of which one failed by the amounts listed in this paragraph. the retest shall be made on one random test from the heat or lot. If the results on the retest specimen or specimens mccl the specified requirements, the heat or test lot will be accepted. If the results of one retest specimen do not meet the specified requirements. the material is subject to rejection.
