2、 case 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 June 2011.1. Scope1.1 This specification covers
3、 emulsified asphalt suitable forapplication in a relatively thick film as a protective coating formetal surfaces.1.2 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
4、shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.
