    Revision of D1970 / D1970M - 18 Standard Specification for Self-Adhering Polymer Modified Bituminous Sheet Materials Used as Steep Roofing Underlayment for Ice Dam Protection

    (What is a Work Item?)

    Active Standard: D1970 / D1970M - 18

    Developed by Subcommittee: D08.02 | Committee D08 | Contact Staff Manager



    ice dam protections; polymer-modifieds; self-adherings; steep roofings; underlayments;;


    A new Significance and Use section was added to the standard on previous ballot D08(18-04), Item 7. A negative voter on that ballot objected to the phrase reasonable amount, but agreed to withdraw his negative based on agreement to ballot a change to that language. This ballot proposes the change suggested by the negative voter, which is a more appropriate and accurate statement. I encourage your support of this ballot item.
