This specification covers the requirements for materials, workmanship, dimensions, performance, and markings for metal insert fittings with o-ring seals and copper crimp rings for use with SDR9 cross-linked polyethylene and SDR9 cross-linked polyethylene/aluminum/cross-linked polyethylene tubing systems. The fittings shall be made from one of the following metals: cast copper alloys, machined brass, forged brass, crimp rings, or o-rings. Insert fittings shall be joined to the tubing by compression of a copper crimp ring around the outer circumference of the tubing, forcing the tubing material into annular spaces formed by ribs on the fitting. Performance tests shall be conducted on the assemblies to determine the material and dimensional requirements of the specimens. Marking shall be applied to the fittings in such a manner that it remains legible after installation and inspection.
