This specification describes requirements and test methods for the qualification of Polyamide 11 (PA 11) bodied mechanical fittings for use with outside diameter controlled PA 11 pipe, and nominal 2 pipe size (IPS) and smaller. In addition, it specifies general requirements of the material from which these fittings are made. Performance requirements shall include tests to determine elevated temperature sustained pressure, tensile strength, in-line fitting, mechanical saddle fittings, temperature cycling, and joint constant tensile load.
