1、Designation: D4811/D4811M 06 (Reapproved 2013)1Standard Specification forNonvulcanized (Uncured) Rubber Sheet Used as RoofFlashing1This standard is issued under the fixed designation D4811/D4811M; the number immediately following the designation indicates theyear of original adoption or, in the case
2、 of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in November 2013.1. Scope1.1 This specification covers
3、nonvulcanized (uncured) rub-ber sheet made of EPDM (ethylene-propylene-diene terpoly-mer) or CR (polychloroprene) intended for use as watertightroof flashing exposed to the weather.1.2 The tests and property limits used to characterize theseflashing materials are specific for each classification and
4、 areminimum values to make the product fit for its intendedpurpose.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Comb
5、iningvalues from the two systems may result in non-conformancewith the standard.1.4 In-place roof system design criteria, such as fireresistance, field seaming strength, material compatibility, anduplift resistance, among others, are beyond the scope of thisspecification.1.5 The following precaution
6、ary caveat pertains to the testmethods portion only, Section 8, of this specification: Thisstandard may involve hazardous materials, operations, andequipment. This standard does not purport to address thesafety concerns associated with its use. It is the responsibilityof the user of this standard to
