Designation:D6551/D6551M05(Reapproved 2011)Standard Practice forAccelerated Weathering of Pressure-Sensitive Tapes byXenon-Arc Exposure Apparatus1This standard is issued under the fixed designation D6551/D6551M;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.1.Scope1.1 This practice describes one environment for the expo-sure of pressure-sensitive tape,used primarily for packaging,toa laboratory accelerated weathering environment.1.2 This practice describes sample preparation and theaccelerated environment to which it shall be exposed.It doesnot specify the length of time of the exposure nor what testsshall be performed on the material following the exposure.1.3 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.1.4 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:2A666 Specification for Annealed or Cold-Worked AusteniticStainless Steel Sheet,Strip,Plate,and Flat BarD3330/D3330M Test Method for PeelAdhesion of Pressure-Sensitive TapeD3715/D3715M Practice for Quality Assurance of Pressure-Sensitive TapesD5105 Practice for Performing Accelerated Outdoor Weath-ering of Pressure-Sensitive Tapes Using ConcentratedNatural SunlightG151 Practice for Exposing Nonmetallic Materials inAccel-erated Test Devices that Use Laboratory Light SourcesG155 Practice for Operating Xenon Arc Light Apparatus forExposure of Non-Metallic Materials3.Summary of Practice3.1 The pressure-sensitive tape is exposed for the timespecified in accordance with the conditions provided in Prac-tice G155.Following this exposure the specimen is ready for aprescribed examination of physical characteristics by otherstandards as determined by the applicable material specifica-tion or other document.4.Significance and Use4.1 This practice describes one method for acceleratedweathering of pressure-sensitive tapes used primarily forpackaging.It is not intended for evaluation the weatheringcharacteristics of pressure-sensitive tapes used in long-termoutdoor exposure conditions(see Practice D5105).4.2 This practice does not necessarily provide direct simu-lation of natural exposure.4.3 Results from use of this practice shall not be representedas being equivalent to those of any natural weathering test untila satisfactory degree of correlation has been established for thematerial in question.4.4 Variation in results are possible when operating condi-tions vary within accepted limits for the instrument specified inPractices G151 and G155.5.Apparatus5.1 Exposure Apparatus,a xenon-arc weathering apparatuswith daylight filters conforming to all parameters as describedin Practices G151 and G155.5.2 Panels3,4,for holding or supporting specimens approxi-mately 75 by 225 mm 3 by 9 in.and rigid enough to resistdeformation during use.1This practice is under the jurisdiction of ASTM Committee D10 on Packagingand is the direct responsibility of Subcommittee D10.14 on Tape and Labels.Current edition approved Aug.1,2011.Published November 2011.Originallyapproved in 2000.Last previous edition approved in 2005 as D6551/D6551M 05.DOI:10.1520/D6551_D6551M-05R11.2For 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 sole source of supply of the apparatus known to the committee at this timeis Chemsultants International,9349 Hamilton Dr.,Mentor,OH 440611118.If youare aware of alternative suppliers,please provide this information to ASTMInternational Headquarters.Your comments will receive careful consideration at ameeting of the responsible technical committee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2.1 The material shall be Type 302 or 304 stainless steel inaccordance with Specification A666 having a bright annealedfinish.The surface roughness height shall be 50 6 5 mm 2.06 0.1-in.arithmetical average deviation from the mean line.5.2.2 Other dimensions or materials and finishes are accept-able when defined by the subsequent test standard or commod-ity specification.5.2.3 A panel or frame of the dimensions required by theexposure apparatus may be use
