1、Designation:C1670/C1670M18Standard Specification forAdhered Manufactured Stone Masonry Veneer Units1This standard is issued under the fixed designation C1670/C1670M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last rev
2、ision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe purpose of this standard is to establish the minimum product specifications for adheredmanufactured stone masonry veneer units
3、.These units are manufactured using a wet cast concretemixture and finished to simulate stone,rocks found in nature,and other textures.1.Scope*1.1 This specification covers the minimum product require-ments for adhered manufactured stone masonry veneer unitsapplied as an adhered veneer to exterior a
4、nd interior walls andstructures suitable to receive units.1.2 The property requirements of this specification apply atthe time of delivery.This standard does not address thephysical evaluation of installed units removed from service.1.3 The units described by this specification are manufac-tured fro
5、m a mixture of cement,normal or lightweight aggre-gates(or a combination of both),water,admixtures,othercementitious materials and other components which are wet-cast into shapes simulating the appearance of natural stone andother textures.1.4 The values stated in either SI units or inch-pound units
6、are 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.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 The text of this specification references notes
7、 andfootnotes which provide explanatory material.These notes andfootnotes shall not be considered as requirements of thestandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish ap
8、pro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.NOTE1When particular features are desired such as surface texturesor color these features should be specified separately.Suppliers should beconsulted as to the availability of
9、 units having the desired features.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade
