ASTM WK46362

    Revision of F2968 / F2968M - 14 Standard Specification for Black Crosslinked Polyethylene (PEX) Pipe, Fittings and Joints For Gas Distribution Applications

    (What is a Work Item?)

    Active Standard: F2968 / F2968M - 14

    Developed by Subcommittee: F17.60 | Committee F17 | Contact Staff Manager



    WK46362

    1. Rationale

    1)Per discussion at our last F17.60 meeting, I am adding gas transmission to the scope, similar to the project for ASTM D2513. 2)Per agreement at our task group meeting, I am proposing to change the definition for PEX in this standard to be consistent with the PEX definition in ASTM F876. The PEX manufacturers agreed to the F876 PEX definition and they would like to see the same definition in this PEX standard. 3)When the last ballot was approved, the wall thickness table (Table 3) had metric pipe sizes up to 1000 mm. However, the table for metric outside diameters (Table 2) was cut off at 630 mm. I am adding pipe sizes up to 1000 mm in Table 2 so that the pipe sizes will be consistent with Table 3.
