3、quid penetrant examination of nonporous metal,and nonmetal components.NOTE 1This practice replaces MIL-STD-68661.2 The penetrant examination processes described in thispractice are applicable to in-process, final, and maintenance(in-service) examinations. These processes are applicable forthe detect

4、ion of discontinuities, such as lack of fusion, corro-sion, cracks, laps, cold shuts, and porosity, that are open orconnected to the surface of the component under examination.1.3 Caution must be exercised in the usage of elevatedtemperature with components manufactured from thermoplas-tic materials

5、. 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 stated

6、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.1.5 All

7、 areas of this practice may be open to agreementbetween the cognizant engineering organization and the sup-plier, 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 therespon

Ma

38、terials notconforming to the requirements of AMS 2644 may be usedonly when a waiver is obtained from the cognizant engineeringorganization.6.5.2 Liquid Oxygen (LOX) Compatible MaterialsPenetrant materials tested in accordance with Test MethodD2512 and passing at 70 ftlbf 95 J or higher, shall be use

39、d onLOX wetted surfaces that cannot be thoroughly post-cleaned.Use of these materials shall be in accordance with the materialsupplier instructions and shall require approval of the cogni-zant engineering organization when such materials do not meetthe requirements of AMS 2644.6.6 Equipment and Faci

40、litiesProcessing 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 herein.6.6.1 Viewing AreasAreas where

41、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) ofvisible light when measured at the examination surface. Forstationary fluorescent dye examination, Type I, the ambientvisible light background shall

42、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 shallmeet the requirements of 7.8.4.1. Viewing areas for portablefluorescent dye examination shall utilize dark canvas, photog-raphers black cloth, or ot

43、her methods to reduce the visiblelight background to the lowest possible level during examina-tion and black light intensity shall meet the above require-ments.6.6.1.1 Where lamps are physically too large to directlyilluminate the examination surface, special lighting, such asUV pencil lights, or UV

44、 light guides, or remote visualexamination equipment shall be used. When using a borescope,the image viewed must have sufficient resolution to effectivelyevaluate the indication. Light intensity shall be measured at theexpected working distance and shall be a minimum 1000W/cm2.6.6.2 Drying OvenWhen

45、components are oven dried, thedryer must be a forced-air recirculating 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 con

46、tamination of the parts. Thetemperature shall be controlled with a calibrated device ca-pable of maintaining the oven temperature at 615F (9.44C)of the temperature for which it is set. The oven shall not exceed160F (71C). The temperature indicator shall be accurate to610F (12.22C) of the actual oven

47、 temperature.6.7 Written ProceduresAll liquid penetrant examinationprocedures are similar for many components, a master writtenprocedure may be utilized that covers the details common to avariety of components. All written procedures, including tech-nique sheets for specific parts shall be approved

48、by anindividual who is a qualified and certified Level III forpenetrant examination in accordance with the requirements of6.3. As a minimum, the following information is requiredeither in individual procedures, specific technique sheets, or amaster procedure, or a combination thereof:6.7.1 Details o

49、f the precleaning and etching process, includ-ing the materials used and specification or other documentcontrolling the examination process, the drying parameters andthe processing times. If these operations are performed byother than examination personnel, details concerning the op-erations may be specified in other documents but must bereferenced in the procedure(s).
