2、f 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 June 2012.1. Scope1.1 This specification covers coal t
3、ar roof cement suitable for trowel application in coal tar roofing and flashing systems.1.2The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.2 The values stated in either SI units or inch-pound units are to be regarded separa
4、tely 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 standard.1.3 This standard does not purport to address all of the safety concer
