    WK45636

    1. Rationale

    This is a two part revision. 1. To add the option of having a fabric (felt) backing to the Type II membrane, such as the Type III and IV membranes allow. 2. To add the test method noted in the annex of this Standard for measuring the thickness over scrim (reinforcing fabric) of the weather side film to the main body of the test methods. This will follow the practice already completed for Standards D4637 and D6878.
