Inspection :
Flattening and Flaring Test:
Flattening Test-–A test 4 to 6 in.（100-150mm）in length shall be flattened between parallel plates with the weld 90°from the direction of applied force(at the point of maximum bending)untillopposite walls of the tubing meet.Except as allowed in S6.2.1, no opening in the weld shall take place until the distance between the plates is less than two thirds of original outside diameter of the tubing,but in no case less than five times the thickness of the tubing wall.Evidence of lamination or burn material shall not develop during the flattening process, and the weld shall not show injurious defects. S6.2.1 when low D- to -t ratio tubing is tested, because the strainimposed due to geometry is unreasonably high on the inside surface at the six and twelve o’clock locations,cracks at these locations shall not be cause for rejection if the D-to -t ratio is less than 10.
Flaring Test—A section of tube approximately 4in.(100mm) in length shall stand being flared with a tool having a 60° included angle until the tube at the mouth of the flare has been expanded 15% of the inside diameter, without cracking or showing flawns.S 6.4 in order to properly evaluateweld quality ,the producer at his option may normalize the test specimen prior to testing. S6.5 Number of tests and retests:S6.5.1 Two Falttening and two flaring tests shallbe made from each lot as specified. Each tested specimen shall conform to the respective rtequirement(see note S1). S 6.5.2 if the results of the testing do not conform to the requirements,retests shall be made on four additional specimens,each of which shall conform to the respective requirement.
