1、Designation:E141810Standard 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 n
2、umber 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 practi
3、ce 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,metal
4、lic 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-washab
5、le 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
6、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 produc
7、ed,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 u
8、nits 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
9、 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
10、 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:2D1
