2、A number in parentheses 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 Department of Defense.1 NOTECorrections were editorially made throughout the standard

3、in March 2012.1. Scope*1.1 This practice establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal, andnonmetal components.NOTE 1This practice replaces MIL-STD-6866.1.2 The penetrant examination processes described in this practice are applicable to in-proce

4、ss, final, and maintenance(in-service) examinations. These processes are applicable for the detection of discontinuities, such as lack of fusion, corrosion,cracks, laps, cold shuts, and porosity, that are open or connected to the surface of the component under examination.1.3 Caution must be exercis

5、ed in the usage of elevated temperature with components manufactured from thermoplasticmaterials. Also, some cleaners, penetrants, and developers can have a deleterious effect on nonmetallic materials such as plastics.Prior to examination, tests should be conducted to ensure that none of the cleanin

6、g or examination materials are harmful to thecomponents to be examined.1.4 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values statedin each system may not be exact equivalents; therefore, each system shall be used independently of the

7、other. Combining valuesfrom the two systems may result in non-conformance with the standard.1.5 All areas of this practice may be open to agreement between the cognizant engineering organization and the supplier, orspecific direction from the cognizant engineering organization.1.6 This standard does

8、 not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

General

34、Practices6.1 Responsibility for ExaminationUnless otherwise specified in the contract or purchase order, the cognizant engineeringorganization is responsible for the performance of all examination requirements as specified herein. The cognizant engineeringorganization may specify more stringent requ

35、irements than the minimum specified in this practice when necessary to ensure thata component meets its functional and reliability requirements. Except as otherwise specified, the supplier may utilize his ownfacilities or any other facilities suitable for the performance of the examination requireme

36、nts specified herein. The purchaserreserves the right to perform any of the examinations set forth in this practice where such examinations are deemed necessary toensure that supplies and services conform to prescribed requirements.6.2 SpecifyingWhen examination is required in accordance with this p

37、ractice the orders, contracts, or other appropriatedocuments shall specify the criteria by which the acceptability of components is to be evaluated. Engineering drawings or otherapplicable documents shall indicate the acceptance criteria for the entire component; zoning may be used. Examination on a

38、sampling basis shall not be allowed unless specifically permitted by the contract.6.3 Personnel QualificationPersonnel performing examinations to this practice shall be qualified and certified in accordancewith ASNT Personnel Qualification SNT-TC-1A, ANSI/ASNT-CP-189 or NAS 410 for military purposes

39、, or as specified in thecontract or purchase order.6.4 Agency QualificationThe agency performing this practice may be evaluated in accordance with Specification E543.6.5 Materials:6.5.1 Qualified MaterialsOnly materials listed or approved for listing on QPL-AMS-2644 (reference AMS 2644) shall beutil

40、ized for penetrant examination.
