JUNE 2015 Page 3 of 5 4.4 Performance Requirements The finished tubing will meet the following requirements when inspected with an unaided eye. See “Methods of Test,” Section 5.3. 4.4.1 Bending The

15、tested sample will show no defect other than superficial outside surface ruptures. ID finish will not deviate from the description specified under “Quality,” Section 5.2. 4.4.2 Upsetting The tested sample will show no defects other than superficial outside surface ruptures. 4.4.3 Dimensional Toleran

16、ces Tubing purchased to this specification will conform to the following tolerances: Outside Diameter : +0.005/- 0.00 inch (+0.13/-0.00 mm) Inside Diameter: 0.0025 inch ( 0.064 mm) 5.0 QUALITY 5.1 Manufacture The tubing will be cold drawn from billets which, after piercing, have had the internal sur

17、face conditioned to remove all hot mill fissures or other defects. After forming, the tubing will be annealed in such a manner as to prevent scale formation on the inside surface and to produce a tube which will meet all requirements of this specification, including being suitable for cold swaging,

18、cold upsetting or cold bending. 5.2 Workmanship and Cleanliness The outside diameter and inside diameter tubing surfaces will be free from scale, rust, seams, laps, laminations, pits or other serious defects. The tubing will be finished on a mandrel to insure a smooth bore of accurate size with no f

19、issures, seams, laps, etc., deeper than 0.005 inch (0.13 mm) or 5% of the wall, whichever is less. In addition, there will be no more than 3 fissures, seams, laps, etc., between 0.003 and 0.005 inch (0.08 to 0.13 mm) or 5% of the wall, whichever is less, and no more than 10 fissures, seams, laps, et

20、c., between 0.002 to 0.003 (0.05 to 0.08 mm) in any transverse cross section of the tubing inspected. 5.3 Methods of Test 5.3.1 Tensile Test Perform this test in accordance with the applicable portions of ASTM A 370. Determine the yield strength by the 0.2% offset method. 5.3.2 Hardness Test Perform

21、 this test on the inside surface of a specimen cut longitudinally from the tubing. Avoid cold working of tubing before testing. 5.3.3 Bending Test Bend the tube around a rod of diameter equal to the outside diameter of the tube through the angle of 180 degrees. Examine for defects. 5.3.4 Upsetting U

22、pset a tube length equal to twice its outside diameter, compressing it longitudinally to a length equal to its outside diameter. Examine for defects. 6.0 QUALIFICATION Engineering qualification of sources is required in advance of production shipments. Samples shall be accompanied by test data certi
