In applying torsion, the rotational force, not to exceed 60 ft/lb (81.3 J) shall be held for 3 seconds. The means of applying torque shall then be returned to the original position and the rotational force applied in the opposite direction.
At the completion of 30 cycles the connector shall comply with 2.2, Leakage.
This test shall be applied to each nominal diameter, type and material of connector submitted for
examination under this standard.
2.8 Reconnection Of Fittings
A connector shall not leak as a result of being connected, disconnected and reconnected.
Method of Test
Connectors employed for this test shall be new and shall include two samples of each nominal diameter, type and material.
The connector to be tested shall be connected to a leakproof system in such a manner that the pipe thread end of the fitting is held rigid.
The union shall be tightened by the application of torque not to exceed the minimum torque specified in Table Ill, Applied Torque During Reconnection of Fittings Test. The connector shall then be leak tested as described in Section 2.2, Leakage. If the connector leaks, the torque shall be increased sufficiently to overcome the leakage, but not in excess of the maximum torque specified in Table Ill. There shall be no leakage in excess of that specified in 2.2, Leakage, after the union is tightened as specified in this paragraph.
A split section of rigid pipe clamped together to obtain a snug fit over the connector, with edges rounded at the ends, shall then be snugly fitted over the tubing with its nearest edge a distance from the top of the fitting equal to the internal diameter of the tubing. This pipe shall be used as a handle to deflect the tubing at the fitting 60 degrees (1 .05 rad) in one direction from the center line of the fitting. The tubing shall then be returned to its original position, deflected 60 degrees (1.05 rad) in the opposite direction, and again returned to its original position. The test for leakage shall again be applied as outlined above. There shall be no evidence of leakage in excess of that specified in 2.2, Leakage, at this time or during any subsequent test.
The union shall then be disconnected, the tubing rotated 55 degrees (0.96 rad) in a clockwise direction, and the union again assembled to the fitting and tightened by the application of a torque not to exceed the torque determined to be necessary to overcome leakage in the previous connection. Leakage tests shall again be applied as outlined above. CSA 6.16-2009 pdf free download.
