QUALITY ASSURANCE PROVISIONS 4.1 Respo
39、nsibility for Inspection The vendor of tubing shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the tubing conforms to specified
40、 requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), tensile properties (3.4.1), pressure test (3.4.4), flarability (3.4.6), and tolerances (3.6) are acceptance tests and shall be performed on each lot. 4.2.2 Periodic Tests Flattening (3.4.2), bending (3.4.3), and emb
41、rittlement (3.4.5) are periodic tests and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.3 Sampling and Testing Shall be in accordance with ASTM B 251 or ASTM B 251M and as follows: 4.3.1 An inspection lot shall consist of 1000 tubes
42、 or 5000 pounds (2268 kg), whichever constitutes the greater mass, of tubes of the same size, type, and temper. 4.3.2 Samples selected in accordance with Table 8 shall be examined for conformance to sizes and weights, tolerances, identification marking, and preparation for delivery requirements.

44、nominal ID. One specimen from each tube selected shall be tested to represent the lot. For an ID of 2 to 6 inches (51 to 152 mm), specimens shall be cut longitudinally; for ID over 6 inches (152 mm), specimens shall be cut circumferentially. Specimens shall be heated to a cherry red and straightened
45、 when hot, annealed, and machined to the plate-type standard specimen with an 8 inch (203 mm) gage length, in accordance with ASTM E 8/8M. For wall thickness up to 1/4 inch (6.4 mm), incl, the width of the narrow part of the specimen shall be approximately 1-1/2 inches (38 mm). For thicker pieces, t
46、he width shall be such as to give a cross-section of 0.5 square inch (322 mm2), but the breadth shall not in any case be less than the thickness. The surfaces shall not be machined but shall be left in their original condition. SAE INTERNATIONAL AMS4554B Page 8 of 9 4.4.2 Flattening Test For all tub
47、ing under 2 inches (51 mm) in OD, the length of tubing selected for the test remaining after the embrittlement test shall be flattened on different elements throughout its length so that a gage set at three times the thickness of the metal shall pass over the tube freely throughout the flattened par
48、t, except at such points where changes in the elements of the flattening take place. The tubing shall be rotated approximately 90 degrees between each successive flattening element. For tubing nominally 2 inches (51 mm) and over in OD, a section 4 inches (102 mm) long shall be flattened so that a gage set at three times the wall thickness shall pass over the tubing freely throughout the flattened part. 4.4.3 Bending Test When tubing 2 inches (51 mm) and under is ordered fully annealed, full sections of tubing shall withstand bending 180 degrees ar
