ASTM WK45424

    Revision of F2159 - 11 Standard Specification for Plastic Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Polyethylene of Raised Temperature (PE-RT) Tubing

    (What is a Work Item?)

    Active Standard: F2159 - 14

    Developed by Subcommittee: F17.10 | Committee F17 | Contact Staff Manager



    WK45424

    1. Rationale

    To revise marking language to be consistant with F1807 and to also allow for optional marking on crimp rings as substitute for existing requirement to be black in color. The original intention of black in color was to help plumbers and code inspectors recognize the rings as being specifically for PEX and not for PB which used a bright copper ring. Over the last several years it has been demonstrated that there are alternate ways to clearly mark the rings so that they still clearly identify PEX. This project is not to eliminate the black in color but to only add alternate marking option if the manufacturer so chooses. Also, I will update this fitting standard to reflect the relatively recent changes to F876 and F877 whereas F876 now only is relavent to the tubing standard and reference to F877 should not be referenced when only referring to the PEX tubing.
