Designation:E141816Standard Practice forVisible Penetrant Testing Using the Water-WashableProcess1This standard is issued under the fixed designation E1418;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 describes procedures for visible liquidpenetrant examination utilizing the water-washable process.Itis a nondestructive practice for detecting discontinuities thatare open to the surface such as cracks,seams,laps,cold shuts,laminations,isolated porosity,through leaks or lack of fusionand is applicable to in-process,final,and maintenance exami-nation.This practice can be effectively used in the examinationof nonporous,metallic materials,both ferrous and nonferrous,and of nonmetallic materials such as glazed or fully densifiedceramics,and certain nonporous plastics,and glass.1.2 This practice also provides the following references:1.2.1 A reference by which visible penetrant examinationprocedures using the water-washable process can be reviewedto ascertain their applicability and completeness.1.2.2 For use in the preparation of process specificationsdealing with the visible,water-washable liquid penetrant ex-amination of materials and parts.Agreement between the userand the supplier regarding specific techniques is stronglyrecommended.1.2.3 For use in the organization of the facilities andpersonnel concerned with the liquid penetrant examination.1.3 This practice does not indicate or suggest criteria forevaluation of the indications obtained.It should be noted,however,that after indications have been produced,they mustbe interpreted or classified and then evaluated.For this purposethere must be a separate code,specification,or a specificagreement to define the type,size,location,and orientation ofindications considered acceptable,and those considered unac-ceptable.1.4 The values stated in inch-pound units are regarded asstandard.SI units given in parentheses are for information only.1.5 Basis of ApplicationThere are areas in this practicethat may require agreement between the cognizant engineeringorganization and the supplier,or specific direction from thecognizant engineering organization.These areas are identifiedas follows:1.5.1 Penetrant type,method and sensitivity,1.5.2 Accept/reject criteria,1.5.3 Personnel qualification requirements,1.5.4 Grit blasting,1.5.5 Etching,1.5.6 Indication/discontinuity sizing,1.5.7 Total processing time,and1.5.8 Marking of parts.1.6 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:2D129 Test Method for Sulfur in Petroleum Products(Gen-eral High Pressure Decomposition Device Method)D516 Test Method for Sulfate Ion in WaterD808 Test Method for Chlorine in New and Used PetroleumProducts(High Pressure Decomposition Device Method)D1552 Test Method for Sulfur in Petroleum Products byHigh Temperature Combustion and Infrared(IR)Detec-tion or Thermal Conducitivity Detection(TCD)E165/E165M Practice for Liquid Penetrant Examination forGeneral IndustryE433 Reference Photographs for Liquid Penetrant Inspec-tionE543 Specification for Agencies Performing NondestructiveTestingE1219 Practice for Fluorescent Liquid Penetrant TestingUsing the Solvent-Removable ProcessE1316 Terminology for Nondestructive Examinations1This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and is the direct responsibility of Subcommittee E07.03 on LiquidPenetrant and Magnetic Particle Methods.Current edition approved Aug.1,2016.Published August 2016.Originallyapproved in 1991.Last previous edition approved in 2010 as E1418-10.DOI:10.1520/E1418-16.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.2 ASNT Standards:Recommended Practice SNT-TC-1A for NondestructiveTesting Personnel Qualification and Certification3ANSI/ASNT-CP-189 Standard for Qualification and Certifi-cation of NDT Personnel32.3 Other Standards:ISO 9712 Non-destructive TestingQualification and Cer-tification of NDT PersonnelGeneral Principles4AMS 2644 Inspection Material,Penetrant52.4 AIA Standard:NAS-410 Certification and Qualification of NondestructiveTest Personnel62.5 DoD ContractsUnless otherwise specified,the issue of the documents thatare DoD adopted are those listed in the issue of theDoDI
