1、Designation: D1863/D1863M 05 (Reapproved 2018)Standard Specification forMineral Aggregate Used on Built-Up Roofs1This standard is issued under the fixed designation D1863/D1863M; 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 U.S. Department of Defense.1. Scope1.1 This specification cover
3、s the quality and grading ofcrushed stone, crushed slag, and water-worn gravel suitable foruse as coarse mineral aggregate on built-up roofs.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 equival
4、ents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Dec
5、ision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.
