Designation:G15110Standard Practice forExposing Nonmetallic Materials in Accelerated Test Devicesthat Use Laboratory Light Sources1This standard is issued under the fixed designation G151;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 This practice provides general procedures to be usedwhen exposing nonmetallic materials in accelerated test de-vices that use laboratory light sources.Detailed informationregarding procedures to be used for specific devices are foundin standards describing the particular device being used.Forexample,detailed information covering exposures in devicesthat use open flame carbon arc,enclosed carbon arc,xenon arcand fluorescent UV light source are found in Practices G152,G153,G154,and G155 respectively.NOTE1Carbon-arc,xenon arc,and fluorescent UV exposures werealso described in Practices G23,G26,and G53 which referred to veryspecific equipment designs.Practices G152,G153,and G154,and G155are performance based standards that replace Practices G23,G26,andG53.1.2 This practice also describes general performance re-quirements for devices used for exposing nonmetallic materialsto laboratory light sources.This information is intendedprimarily for producers of laboratory accelerated exposuredevices.1.3 This practice provides information on the use andinterpretation of data from accelerated exposure tests.Specificinformation about methods for determining the property of anonmetallic material before and after exposure are found instandards describing the method used to measure each prop-erty.Information regarding the reporting of results fromexposure testing of plastic materials is described in PracticeD5870.NOTE2Guide G141 provides information for addressing variability inexposure testing of nonmetallic materials.Guide G169 provides informa-tion for application of statistics to exposure test resultsNOTE3This standard is technically equivalent to ISO 4892,Part 1.1.4 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:2D618 Practice for Conditioning Plastics for TestingD3924 Specification for Environment for Conditioning andTesting Paint,Varnish,Lacquer,and Related MaterialsD5870 Practice for Calculating Property Retention Index ofPlasticsE41 Terminology Relating To ConditioningE171 Practice for Conditioning and Testing Flexible BarrierPackagingE644 Test Methods for Testing Industrial Resistance Ther-mometersE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE772 Terminology of Solar Energy ConversionE839 Test Methods for Sheathed Thermocouples andSheathed Thermocouple CableG23 Practice for Operating Light-Exposure Apparatus(Carbon-Arc Type)With and Without Water for Exposureof Nonmetallic Materials(Withdrawn 2000)3G26 Practice for Operating Light-Exposure Apparatus(Xenon-Arc Type)With and Without Water for Exposureof Nonmetallic Materials(Discontinued 2001)(With-drawn 2000)3G53 Practice for Operating Light-and Water-Exposure Ap-paratus(Fluorescent UV-Condensation Type)for Expo-sure of Nonmetallic Materials(Withdrawn 2000)3G113 Terminology Relating to Natural and Artificial Weath-ering Tests of Nonmetallic MaterialsG130 Test Method for Calibration of Narrow-and Broad-Band Ultraviolet Radiometers Using a SpectroradiometerG141 Guide for Addressing Variability in Exposure Testingof Nonmetallic Materials1This practice is under the jurisdiction ofASTM Committee G03 on Weatheringand Durability and is the direct responsibility of Subcommittee G03.03 onSimulated and Controlled Exposure Tests.Current edition approved April 1,2010.Published May 2010.Originallyapproved in 1997.Last previous edition approved in 2009 as G151 09.DOI:10.1520/G0151-10.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 G147 Practice for Conditioning and Handling of Nonmetal-lic Materials for Natural and Artificial Weathering TestsG152 Practice for Operating Open Flame Carbon Arc LightApparatus for Exposure of Nonmetallic MaterialsG153 Practice for Operating Enclosed Carbon Arc LightApparatus for Exposure of Nonmetallic MaterialsG154 Practice for Operating Fluorescent Ultraviolet(UV)Lamp Apparatus
