Designation:E302218Standard Practice forMeasurement of Emission Characteristics andRequirements for LED UV-A Lamps Used in FluorescentPenetrant and Magnetic Particle Testing1This standard is issued under the fixed designation E3022;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 covers the procedures for testing theperformance of ultraviolet A(UV-A),light emitting diode(LED)lamps used in fluorescent penetrant and fluorescentmagnetic particle testing(see Guides E709 and E2297,andPractices E165/E165M,E1208,E1209,E1210,E1219,E1417/E1417M and E1444).2This specification also includes report-ing and performance requirements for UV-A LED lamps.1.2 These tests are intended to be performed only by themanufacturer to certify performance of specific lamp models(housing,filter,diodes,electronic circuit design,opticalelements,cooling system,and power supply combination)andalso includes limited acceptance tests for individual lampsdelivered to the user.This test procedure is not intended to beutilized by the end user.1.3 This practice is only applicable for UV-A LED lampsused in the examination process.This practice is not applicableto mercury vapor,gas-discharge,arc or luminescent(fluores-cent)lamps or light guides(for example,borescope lightsources).1.4 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.1.5 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.1.6 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:3E165/E165M Practice for Liquid Penetrant Examination forGeneral IndustryE709 Guide for Magnetic Particle TestingE1208 Practice for Fluorescent Liquid Penetrant TestingUsing the Lipophilic Post-Emulsification ProcessE1209 Practice for Fluorescent Liquid Penetrant TestingUsing the Water-Washable ProcessE1210 Practice for Fluorescent Liquid Penetrant TestingUsing the Hydrophilic Post-Emulsification ProcessE1219 Practice for Fluorescent Liquid Penetrant TestingUsing the Solvent-Removable ProcessE1316 Terminology for Nondestructive ExaminationsE1348 Test Method for Transmittance and Color by Spec-trophotometry Using Hemispherical GeometryE1417/E1417M Practice for Liquid Penetrant TestingE1444 Practice for Magnetic Particle TestingE2297 Guide for Use of UV-Aand Visible Light Sources andMeters used in the Liquid Penetrant and Magnetic ParticleMethods2.2 Other Standards:4ANSI/ISO/IEC 17025 General Requirements for the Com-petence of Testing and Calibration Laboratories1This test method is under the jurisdiction of ASTM Committee E07 onNondestructive Testing and is the direct responsibility of Subcommittee E07.03 onLiquid Penetrant and Magnetic Particle Methods.Current edition approved July 1,2018.Published July 2018.Originally approvedin 2015.Last previous edition approved in 2015 as E3022-15.DOI:10.1520/E3022-182The use of LED lamps for penetrant examination may be covered by a patent.Interested parties are invited to submit information regarding the identification ofalternative(s)to this patented item to ASTM International Headquarters.Yourcomments will receive careful consideration at a meeting of the responsibletechnical committee,which you may attend.NOTE:ASTM International takes no position respecting the validity of any patentrights asserted in connection with any item mentioned in this standard.Users of thisstandard are expressly advised that determination of the validity of any such patentrights,and the risk of infringement of such rights,are entirely their ownresponsibility.3For 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.4Available 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization establis
