1、Designation:G15513Standard Practice forOperating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials1This standard is issued under the fixed designation G155;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of la
2、st revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope*1.1 This practice covers the basic principles a
3、nd operatingprocedures for using xenon arc light and water apparatusintended to reproduce the weathering effects that occur whenmaterials are exposed to sunlight(either direct or throughwindow glass)and moisture as rain or dew in actual use.Thispractice is limited to the procedures for obtaining,mea
4、suring,and controlling conditions of exposure.A number of exposureprocedures are listed in an appendix;however,this practicedoes not specify the exposure conditions best suited for thematerial to be tested.NOTE1Practice G151 describes performance criteria for all exposuredevices that use laboratory
5、light sources.This practice replaces PracticeG26,which describes very specific designs for devices used for xenon-arcexposures.The apparatus described in Practice G26 is covered by thispractice.1.2 Test specimens are exposed to filtered xenon arc lightunder controlled environmental conditions.Differ
6、ent types ofxenon arc light sources and different filter combinations aredescribed.1.3 Specimen preparation and evaluation of the results arecovered in ASTM methods or specifications for specificmaterials.General guidance is given in Practice G151 and ISO4892-1.More specific information about method
7、s for deter-mining the change in properties after exposure and reportingthese results is described in Practice D5870.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafe
8、ty 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.1.5.1 Should any ozone be generated from the operation ofthe lamp(s),it shall
9、be carried away from the test specimensand operating personnel by an exhaust system.1.6 This practice is technically similar to the following ISOdocuments:ISO 4892-2,ISO 11341,ISO 105 B02,ISO 105B04,ISO 105 B05,and ISO 105 B06.2.Referenced Documents2.1 ASTM Standards:2D3980 Practice for Interlaborat
