Designation:C118508(Reapproved 2016)Standard Test Methods forSampling and Testing Non-Asbestos Fiber-Cement FlatSheet,Roofing and Siding Shingles,and Clapboards1This standard is issued under the fixed designation C1185;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover sampling and testing ofnon-asbestos fiber-cement flat sheets,roofing shingles,sidingshingles,and clapboards.These products may be smooth orsurface textured.These test methods are utilized in evaluatingproducts cited in Specifications C1186,C1225,C1288,andC1325.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C20 Test Methods for Apparent Porosity,Water Absorption,Apparent Specific Gravity,and Bulk Density of BurnedRefractory Brick and Shapes by Boiling WaterC1154 Terminology for Non-Asbestos Fiber-Reinforced Ce-ment ProductsC1186 Specification for Flat Fiber-Cement SheetsC1225 Specification for Fiber-Cement Roofing Shingles,Shakes,and SlatesC1288 Specification for Discrete Non-Asbestos Fiber-Cement Interior Substrate SheetsC1325 Specification for Non-Asbestos Fiber-Mat Rein-forced Cementitious Backer Units2.2 ISO Standards:ISO 390 Product in Fiber Reinforced Cement Sampling andInspection3ISO 2859-0 Sampling Procedures for Inspection byAttributesPart 0:Introduction to the ISO 2859 AttributeSampling System3ISO 2859-1 Sampling Procedures for Inspection byAttributesPart 1:Sampling Schemes Indexed byAccep-tance Quality Limit(AQL)for Lot-by-Lot Inspection3ISO 3951 Sampling Procedures and Charts for Inspection byVariables for Percent Nonconforming33.Terminology3.1 Definitions:3.1.1Refer to Terminology C1154.3.1.2 densitythe mass per unit volume expressed inpounds per cubic foot(lb/ft3)or kilograms per cubic metre(kg/m3).3.1.3 flexural strengththe average flexural strength is theaverage of two perpendicular breaks expressed in pound-forceper square inch(megapascals)as calculated from the averagebreaking load of wet or equilibrium test specimens,loaded assimple beams,with the load applied at the center.3.1.4 heat-rain sheetsfixed to a building frame in accor-dance with the manufacturers recommended installation prac-tices.The sheeted frame is then subjected to alternate wettingand heating cycles and any structural alteration of the sheetcaused by the test is reported.3.2 Definitions of Terms Specific to This Standard:3.2.1 dimensionsfor the purpose of these test methods,thelength,width and thickness of fiber-cement flat sheets,roofingshingles,siding shingles,and clapboard are measured underspecified conditions.3.2.2 moisture contentfor the purpose of these testmethods,the percentage of moisture content of the fiber-cement product when conditioned at 50 6 5%relativehumidity and a temperature of 73 6 4F(23 6 2C).1These test methods are under the jurisdiction of ASTM Committee C17 onFiber-Reinforced Cement Products and are the direct responsibility of Subcommit-tee C17.02 on Non-Asbestos Fiber Cement Products.Current edition approved Nov.1,2016.Published November 2016.Originallyapproved in 1991.Last previous edition approved in 2012 as C1185-08(2012).DOI:10.1520/C1185-08R16.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.3 moisture movementin these test methods,the linearvariation in length and width of test specimen,with change inmoisture content.3.2.4 water absorptionfor the purpose of these testmethods,the increase in mass of the test specimen expressed asa percentage of its dry mass after immersion in water for aspecified period of time as prescribed.4.Sampling and Inspection4.1 Employ sampling procedures providing an acceptablequality level(AQL)of 4%at a 90%confidence level with asample size given by special inspection level S3,except wherespecific sampling is required by particular test procedures.4.2 Acceptable Quality Level(AQL)The acceptable qual-ity level(AQL)may be defined as fo
