ASTM WK69970

    Revision of F3348 - 19 Standard Specification for Plastic Press Insert Fittings with Factory Assembled Stainless Steel Press Sleeve for SDR9 Cross-linked Polyethylene (PEX) Tubing

    (What is a Work Item?)

    Active Standard: F3348 - 20

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



    cold and hot water distribution; cross-linked polyethylene; PEX; plastic insert fittings; plastic press insert fittings; press joints; stainless steel press sleeves;;


    Add language to the Product Marking section requiring the ASTM standard number to be marked only if size permits. Some fittings (e.g. 3/8 nominal) may be too small for both a trademark and the ASTM number to fit, and placing the ASTM marking on packaging will suffice in such cases. ASTM F1807, arguably the most widespread PEX/PE-RT fitting standard in use, contains such language which I propose should be added to F3348.
