ASTM WK40920

    Work Item: ASTM WK40920 - Revision of D3746 - 85(2008) Standard Test Method for Impact Resistance of Bituminous Roofing Systems

    (What is a Work Item?)

    Active Standard: D3746 - 85(2008)

    Developed by Subcommittee: D08.20 | Committee D08 | Contact Staff Manager



    1. Rationale

    Paragraph 10.7.3 currently calls for extraction of the bitumen by immersing in warm 1,1,1 trichloroethane (for asphalt based membranes) or xylene (for coal tar based membranes). Both solvents are considered toxic and should be avoided. I am proposing a change, the precedent for my proposed change is currently included in D228 09.
