Fluorescent Penetrant Method4.1 Perform fluorescent penetrant inspection of metallicsurgical implants in accordance with Practice E 165, MethodA.4.2 The penetrant system used shall conform to a minimumof Sensitivity Level 3, in accordance with the latest revision ofAMS 264
7、4.4.3 All penetrant materials shall be compatible with eachother.5. Penetrant Method Materials Control5.1 The penetrant method materials deteriorate in usefulnessthrough contamination and age. The following controls shouldbe used to evaluate the materials usefulness unless thesuppliers requirements
8、are more stringent:5.1.1 Penetrants:5.1.1.1 Water ContentWhere there is a possibility ofwater contamination to penetrant materials, the water contentshould be determined by Test Method D95. The water contentshall not exceed 10 %. The frequency of testing shall be at leastonce every 30 days for open
9、containers.5.1.1.2 Fluorescent BrightnessFluorescent brightnessshould be determined at least once every 30 days or before useby comparison of samples of the working penetrant to a sampleof new penetrant under black light. No visible difference shallbe allowed.5.1.2 Developer:5.1.2.1 DryThe developer
10、 should be dry and fluffy. De-velopers showing evidence of fluorescence when compared tonew developer shall not be used.5.1.2.2 WetA method should be employed to ensureadequate suspension of the wet developer prior to use. Thespecific gravity of the developer should be from 1.018 to 1.034.This metho
11、d does not apply to nonaqueous solvent developerdue to the volatile nature of the product.1This practice is under the jurisdiction ofASTM Committee F04 on Medical andSurgical Materials and Devices and is the direct responsibility of SubcommitteeF04.12 on Metallurgical Materials.Current edition appro

17、ivalent.8. Keywords8.1 fluorescent; penetrant inspection; testing methods; sur-gical implantsAPPENDIX(Nonmandatory Information)X1. RATIONALEX1.1 A method of nondestructive inspection, known asfluorescent penetrant inspection, is employed as a qualitycontrol tool for surgical devices. This method of
18、inspection isnot only used by the manufacturers, but by their suppliers andalso independent testing laboratories. This method has beenused for over twenty years for the nondestructive examinationof surgical implants and devices. Fluorescent penetrant inspec-tion provides a sensitive method of detect
19、ing surface imper-fections such as scratches, cracks, surface porosity, and weld-ing joint imperfections.X1.2 Fluorescent penetrant inspection uses specially for-mulated penetrating oil, manufactured by many sources, whichalso has a fluorescent dye as part of its formula. The method ofinspection all
20、ows for the fluorescent penetrating oil to entersurface discontinuities; a subsequent process removes all othersurface remnants of the penetrating oil, thus leaving thefluorescent material only in surface discontinuities. A final“developer” is applied to bring out the penetrating oil from thediscont
21、inuities. Then an ultra violet light (black light) is used toinspect the part for the presence of the fluorescent material.This method allows for highly sensitive examination of smalldiscontinuities that normally would not be visible by unaidedvisual inspection.X1.3 Due to a variety of specification
22、s being applied to theinspection of surgical implants and devices, a task force wasformed under Committee F04 to standardize methods forfluorescent penetrant inspection of metallic surgical implants;the result was Practice F 601. The task force, comprised of alarge cross section of manufacturers, te
23、sting experts, govern-ment representatives, and other interested parties, developed auniversally accepted practice for surgical implants and devices.X1.4 This is a standard practice and is only intended toconfirm the standardized method of obtaining and evaluatingthe fluorescent penetrant indication
24、s, as well as the evaluationof the materials used in the testing method. This practice is notintended to set acceptance standards; this type of specificationwould be extremely difficult due to such variables as surfacefinish (that is, mechanically polished, vapor blasted, electropolished, and so for
25、th); manufacturing method (that is,wrought, forged, cast, and so forth); as well as other variablesin surface texture.SUMMARY OF CHANGESCommittee F04 has identified the location of selected changes to this standard since the last issue (F 601 98)that may impact the use of this standard. (Approved Se
26、pt. 10, 2003.)(1) Changed MIL-I-25135 to AMS 2644 in paragraphs 2.3 and4.2. MIL-I-25135E, Notice 1, 13 March 1998 states, “Futureacquisitions for this material should refer to SAE AMS 2644.”(2) Added Summary of Changes section.F 601 03 (2008)2ASTM International takes no position respecting the valid
27、ity of any patent rights asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subje
28、ct to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised, either reapproved or withdrawn.
