OD surface imperfections, such as handling marks, straightening marks, mandrel or die marks and scale patterns are acceptable providing their depth does not result in violation of minimum wall thickness requi
26、rements and their termination is not sharp when viewed by the naked eye. 3.5.2 Tubing shall be subjected to either ultrasonic inspection or to electromagnetic (eddy-current) testing in accordance with ASTM A1016 except that suspect indications shall not be accepted based on visual observation, i.e.,
27、 indications must be either rejected or reconditioned and retested to pass the test. 3.6 Tolerances Shall be as follows: 3.6.1 Cold Drawn and Annealed Tubing Shall conform to all applicable requirements of AMS2263. 3.6.2 Hot Finished and Annealed Tubing 3.6.2.1 Length and Straightness Shall conform

Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensu
31、re that the tubing conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), tensile properties (3.4.1), and tolerances (3.6) are acceptance tests and shall be performed on each heat or lot as applicable. 4.2.1.1 Nondestructive testing (3.5.2) shall be
32、 performed on each finished tube to assure the requirements of 3.5.1 are met. This requirement shall become effective January 1, 2016. 4.2.2 Periodic Tests Flarability (3.4.2) is a periodic test and shall be performed at a frequency selected by the manufacturer unless frequency of testing is specifi
33、ed by purchaser. 4.3 Sampling and Testing Shall be in accordance with AMS2371 and the following: 4.3.1 Specimens for flarability test (3.4.2) shall be full tubes or sections cut from a tube.
