1、Designation: E1417/E1417M 16Standard Practice forLiquid Penetrant Testing1This standard is issued under the fixed designation E1417/E1417M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in pare

2、ntheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This practice establishes the minimum requirements forconducti

3、ng liquid penetrant examination of nonporous metal,and nonmetal components.NOTE 1This practice replaces MIL-STD-6866.1.2 The penetrant examination processes described in thispractice are applicable to in-process, final, and maintenance(in-service) examinations. These processes are applicable forthe

4、detection of discontinuities, such as lack of fusion,corrosion, cracks, laps, cold shuts, and porosity, that are openor connected to the surface of the component under examina-tion.1.3 Caution must be exercised in the usage of elevatedtemperature with components manufactured from thermoplas-tic mate

5、rials. Also, some cleaners, penetrants, and developerscan have a deleterious effect on nonmetallic materials such asplastics. Prior to examination, tests should be conducted toensure that none of the cleaning or examination materials areharmful to the components to be examined.1.4 UnitsThe values st

6、ated in either SI units or inch-pound units are to be regarded separately as standard. Thevalues stated in each system may not be exact equivalents;therefore, each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.1.

7、5 All areas of this practice may be open to agreementbetween the cognizant engineering organization and thesupplier, or specific direction from the cognizant engineeringorganization.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theres

8、ponsibility 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.

General Practices6.1 Responsibility for ExaminationUnless otherwisespecified in the contract or purchase order, the cognizantengineering organization is responsible for the performance

33、ofall examination requirements as specified herein. The cogni-zant engineering organization may specify more stringentrequirements than the minimum specified in this practice whennecessary to ensure that a component meets its functional andreliability requirements. Except as otherwise specified, the

34、supplier may utilize his own facilities or any other facilitiessuitable for the performance of the examination requirementsspecified herein. The purchaser reserves the right to performany of the examinations set forth in this practice where suchexaminations are deemed necessary to ensure that suppli

35、es andservices conform to prescribed requirements.6.2 SpecifyingWhen examination is required in accor-dance with this practice the orders, contracts, or other appro-priate documents shall specify the criteria by which theacceptability of components is to be evaluated. Engineeringdrawings or other ap

36、plicable documents shall indicate theacceptance criteria for the entire component; zoning may beused. Examination on a sampling basis shall not be allowedunless specifically permitted by the contract.6.3 Personnel QualificationPersonnel performing exami-nations to this practice shall be qualified an

37、d certified inaccordance with ASNT Personnel Qualification SNT-TC-1A,ANSI/ASNT-CP-189 or NAS 410 for military purposes, or asspecified in the contract or purchase order.6.4 Agency QualificationThe agency performing thispractice may be evaluated in accordance with SpecificationE543.6.5 Materials:6.5.

38、1 Qualified MaterialsOnly materials listed or ap-proved for listing on QPL-AMS-2644 (reference AMS 2644)shall be utilized for penetrant examination. Materials notconforming to the requirements of AMS 2644 may be usedonly when a waiver is obtained from the cognizant engineeringorganization.6.5.2 Liqu

39、id Oxygen (LOX) Compatible MaterialsPenetrant materials tested in accordance with Test MethodD2512 and passing at 70 ftlbf 95 J or higher, shall be used onLOX wetted surfaces that cannot be thoroughly post-cleaned.Use of these materials shall be in accordance with the materialsupplier instructions a

40、nd shall require approval of the cogni-zant engineering organization when such materials do not meetthe requirements of AMS 2644.6.6 Equipment and FacilitiesProcessing equipment usedin the penetrant examination process shall be constructed andarranged to permit a uniform and controlled operation. Th

41、eequipment shall meet all applicable national and local safetyrequirements as well as the requirements specified herein.6.6.1 Viewing AreasAreas where parts are reviewed shallbe kept clean at all times. For visible dye examination, Type II,the lighting system shall provide at least 100 fc 1076 lx of

42、visible light when measured at the examination surface. Forstationary fluorescent dye examination, Type I, the ambientvisible light background shall not exceed 2 fc 21.5 lx at theexamination surface. The black lights shall provide a minimumof 1000 W/cm2at the examination surface. Black lights shallm

43、eet the requirements of 7.8.4.1. Viewing areas for portablefluorescent dye examination shall utilize dark canvas, photog-raphers black cloth, or other methods to reduce the visiblelight background to the lowest possible level during examina-tion and black light intensity shall meet the above require

44、-ments.6.6.1.1 Where lamps are physically too large to directlyilluminate the examination surface, special lighting, such asUV pencil lights, or UV light guides, or remote visualexamination equipment shall be used. When using a borescope,the image viewed must have sufficient resolution to effectivel

45、yevaluate the indication. Light intensity shall be measured at theexpected working distance and shall be a minimum 1000W/cm2.6.6.1.2 LED UV-Alamps used for evaluation purposes shallcomply with Practice E3022.6.6.2 Drying OvenWhen components are oven dried, thedryer must be a forced-air recirculating

46、 type. In automatedsystems, where parts are dried by radiant heat and forced air,the travel speed of the system shall be such as to precludeoverdrying of parts. The forced air does not have to berecirculating but must preclude contamination of the parts. Thetemperature shall be controlled with a cal

47、ibrated device ca-pable of maintaining the oven temperature at 615F 8.3C ofthe temperature for which it is set. The oven shall not exceed160F 71C. The temperature indicator shall be accurate to610F 5.6C of the actual oven temperature.6.7 Written ProceduresAll liquid penetrant examinationprocedures a
