A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or This Practice establishes the minimum requirements forconducting Liquid Penetrant Examination of nonporous metal,and nonmetal The Penetrant Examination processes described in thispractice are applicable to in-process, final, and maintenance(in-service) inspections. These processes are applicable for thedetection of discontinuities, such as lack of fusion, corrosion,cracks, laps, cold shuts, and porosity, that are open or con-nected to the surface of the component under Caution must be exercised in the usage of elevatedtemperature with components manufactured from thermoplas-tic materials.

2 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 inspection materials areharmful to the components to be The values stated in inch-pound units are regarded asstandard. The SI units given in parentheses are for All areas of this Practice may be open to agreementbetween the cognizant engineering organization and the sup-plier, or specific direction from the cognizant 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 precau-tionary statements are given in Notes 2 and Referenced The following documents form a part of this Practice tothe extent specified standards .

Copyright Standard :9 AMS 2644 Inspection Material, Contracts Unless otherwise specified, the issuesof the documents that are DoD adopted are those listed in theissue of the DoDISS (Department of Defense Index of Speci-fications and standards ) cited in the of Precedence In the event of conflict betweenthe text of this Practice and the references cited herein, the textof this Practice takes The terminology relating to Liquid Penetrant examina-tion that appears in Terminology E 1316 shall apply to theterms used in this of Terms Specific to This any component that will be installed on asystem that engineering organization the company,agency, or other authority responsible for the design or afterdelivery, end use of the system or component for which liquidpenetrant Examination is required.

6 In addition to design per-sonnel, this may include personnel from material, and processengineering, stress analysis, NDT or quality groups and others,as the part(s) or element(s) of a systemdescribed, assembled, or processed to the extent specified bythe Examination the final Examination performedfor the acceptance of the item. Any change to the item s surfacesuch as machining, grinding, welding, heat treatment, oretching by subsequent manufacturing operation, may renderthe previous Examination invalid, requiring reexamination ofall affected surfaces, unless otherwise approved in the that which occurs during manufacturingbefore a component is in final refers to components that are in use orstorage for their intended indication Penetrant indications with at least athree to one length to width repeat, after cleaning, the application andappropriate processing of Penetrant , emulsifier (as required),and developer (as required).

7 Indication Penetrant indication whoselength to width ratio is less than the organization contracted to supply thematerial, parts, or engine critical components any componenton turbine engine designated by the manufacturer as critical. 4. Significance and This Practice establishes the basic parameters for con-trolling the application of the Liquid Penetrant method. Thispractice is written so it can be specified on the engineeringdrawing, specification, or contract. It is not a detailed how-toprocedure to be used by the inspector and, therefore, must besupplemented by a detailed procedure that conforms to therequirements of this Practice . Test Method E 165 containsinformation to help develop detailed how-to Penetrant Examination processes and materials are clas-sified in accordance with the material classification containedin MIL-I-25135 or AMS 2644. Penetrant systems covered bythis Practice shall be of the following types, methods, andsensitivity I Fluorescent II Visible A Water B Post-emulsifiable, C D Post-emulsifiable, (These levels apply to Type I penetrantsystems only.)

8 Type II Penetrant systems have only a singlesensitivity and it is not represented by any of the levels listedas follows) Level1 2 Very Level 1 Level 2 Level 3 Level 4 Developers shall be of the following a Dry b c d Nonaqueous for Type I fluorescent e Nonaqueous for Type II visible f Specific Solvent removers shall be of the following 1 2 3 Specific General for Examination Unless otherwisespecified in the contract or purchase order, the cognizantengineering organization is responsible for the performance ofall Examination requirements as specified herein. The cogni-zant engineering organization shall 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, thesupplier may utilize his own facilities or any other facilitiessuitable for the performance of the Examination requirementsspecified herein.

9 The purchaser reserves the right to performany of the examinations set forth in this Practice where suchexaminations are deemed necessary to ensure that supplies andservices conform to prescribed from Society of Automotive Engineers, 400 Commonwealth Drive,Warrendale, PA When 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. An example ofsuch criteria is in MIL-STD-1907; however, other criteria maybe utilized. Engineering drawings or other applicable docu-ments shall indicate the acceptance criteria for the entirecomponent; zoning may be used. Examination on a samplingbasis shall not be allowed unless specifically permitted by Qualification Personnel performing exami-nations to this Practice shall be qualified and certified inaccordance with ASNT Personnel Qualification SNT-TC-1A,ANSI/ASNT CP-189, NAS 410, or MIL-STD-410 for militarypurposes, or as specified in the contract or purchase Qualification The agency performing thispractice may be evaluated in accordance with Practice E Materials Only materials listed or ap-proved for listing on QPL-25135 or QPL-AMS 2644 (referenceMIL-I-25135 or AMS 2644) shall be utilized for penetrantexamination.

10 Materials not conforming to the requirements ofMIL-I-25135 or AMS 2644 may be used only when a waiveris obtained from the cognizant engineering Oxygen (LOX) Compatible Materials Penetrant materials tested in accordance with Test MethodD 2512 and passing at 70 ft lbf (95 J) or higher, shall be usedon LOX wetted surfaces that cannot be thoroughly post-cleaned. Use of these materials shall be in accordance with thematerial supplier instructions and shall require approval of thecognizant engineering organization when such materials do notmeet the requirements of MIL-I-25135 or and Facilities Processing equipment usedin the Penetrant Examination process shall be constructed andarranged to permit a uniform and controlled operation. Theequipment shall meet all applicable national and local safetyrequirements as well as the requirements specified Areas Areas where parts are reviewed shallbe kept clean at all times.
