1、Designation: D4637/D4637M 12D4637/D4637M 13Standard Specification forEPDM Sheet Used In Single-Ply Roof Membrane1This standard is issued under the fixed designation D4637/D4637M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the
2、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.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers fle
3、xible sheet made from ethylene-propylene-diene terpolymer (EPDM) intended for use insingle-ply roofing membranes exposed to the weather. The tests and property limits used to characterize the sheet are values toensure minimum quality for the intended use. The sheet may be non-reinforced, fabric- or

5、values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the s
