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 revision.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.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 and 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 from 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 unitsare 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 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 appro-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 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 Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:C31/C31M Practice for Making and Curing Concrete TestSpecimens in the FieldC33/C33M Specification for Concrete AggregatesC39/C39M Test Method for Compressive Strength of Cylin-drical Concrete SpecimensC140/C140M Test Methods for Sampling and Testing Con-crete Masonry Units and Related UnitsC150/C150M Specification for Portland CementC157/C157M Test Method for Length Change of HardenedHydraulic-Cement Mortar and ConcreteC207 Specification for Hydrated Lime for Masonry Pur-posesC260/C260M Specification for Air-Entraining Admixturesfor ConcreteC330/C330M Specification for Lightweight Aggregates forStructural ConcreteC331/C331M Specification for Lightweight Aggregates forConcrete Masonry UnitsC482 Test Method for Bond Strength of Ceramic Tile toPortland Cement PasteC494/C494M Specification for Chemical Admixtures forConcreteC511 Specification for Mixing Rooms,Moist Cabinets,Moist Rooms,and Water Storage Tanks Used in theTesting of Hydraulic Cements and ConcretesC595/C595M Specification for Blended Hydraulic CementsC618 Specification for Coal Fly Ash and Raw or Calcined1This test method is under the jurisdiction of ASTM Committee C15 onManufactured Masonry Units and is the direct responsibility of SubcommitteeC15.03 on Concrete Masonry Units and Related Units.Current edition approved July 15,2018.Published August 2018.Originallyapproved in 2013.Last previous edition approved in 2017 as C1670/C1670M 17.DOI:10.1520/C1670_C1670M18.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 Natural Pozzolan for Use in ConcreteC666/C666M Test Method for Resistance of Concrete toRapid Freezing and ThawingC979/C979M Specification for Pigments for Integrally Col-ored ConcreteC989/C989M Specification for Slag Cement for Use inConcrete and MortarsC1116/C1116M
