This specification describes requirements and test methods for the qualification of plastic bodied mechanical fittings for use with outside diameter controlled polyethylene (PE) gas distribution pipe, nominal 2 pipe size (IPS) and smaller. In addition, it specifies general requirements of the material from which these fittings are made. Unless otherwise specified, each nominal size of fitting shall be tested. Testing of the thickest wall pipe that the fitting is designed to be used with qualifies the use of that fitting with pipe of lesser wall thickness. In order to determine the overall performance of the mechanical fittings, the following tests shall be performed: elevated temperature sustained pressure test, tensile strength test, temperature cycling test, constant tensile load joint test (in-line joints only), and rotation test (mechanical saddle fittings only).
