25、le 1.9. Performance Requirements9.1 Expansion Test9.1.1 Specimens in the O61 (annealed) temper shall with-stand an expansion of 25 % of the outside diameter whenexpanded in accordance with Test Method B153. The expandedpipe shall show no cracking or rupture visible to the unaidedeye. Pipe ordered in
26、 the drawn (H) condition is not subject tothis test.NOTE 1The term “unaided eye,” as used herein, permits the use ofcorrective spectacles necessary to obtain normal vision.9.1.2 As an alternative to the expansion test for pipe over 4in. (102 mm) in diameter in the O61 (annealed) condition, asection
27、4 in. in length shall be cut from the end of one of thelengths for a flattening test. This 4-in. specimen shall beflattened so that a gage set at three times the wall thickness willpass over the pipe freely throughout the flattened part. The pipeso tested shall develop no cracks or flaws visible to
28、the unaidedeye (see Note 1) as a result of this test. In making the flatteningtest the elements shall be slowly flattened by one stroke of thepress.9.2 Residual Stress Test:9.2.1 When specified in the contract or purchase order,product of the O61 (annealed) shall be tested for residual stressaccordi
29、ng to the requirements of Test Method B154 or TestMethod B858, and show no signs of cracking.Warning Mercury is a definite health hazard.
