ASTM B 214 Sieve Analysis of Granular Metal Powders ASTM E 1444 Magnetic Particle Examination 3. TECHNICAL REQUIREMENTS 3.1 Material The product shall be composed of durable nonfluoresce

12、nt magnetic particles suitable for use in the dry magnetic particle inspection process in accordance with ASTM E 1444 and which may have been treated to attain the color specified. 3.2 Properties The product shall conform to the following requirements; tests shall be performed on the product supplie

13、d and in accordance with specified test procedures: 3.2.1 Contamination The dry powder shall show no evidence of foreign material or agglomeration, determined by visual examination during the tests to determine other characteristics of the product. 3.2.2 Color The product shall be black, red, gray,

14、or other color, as specified, determined by applying the dry powder onto white paper at least 8-1/2 x 11 inches (216 x 279 mm), completely covering an area not less than 4 inches (102 mm) in diameter. The color shall be observed under a white light of not less than 100 foot-candles (1000 lx) at the

15、examining surface. 3.2.3 Particle Size The magnetic particles shall be of such size that not less than 98% by weight shall pass through a U.S. Standard No. 80 screen/sieve, determined in accordance with ASTM B 214. Determine the dry weight of the residual particulate material not passing through the

16、 screen/sieve as related to the original weight of the sample, expressed in percent. 3.2.4 Sensitivity The product shall provide indications of at least the first eight holes of the test ring specimen of 4.3.1.2 when tested as follows: 3.2.4.1 Place the ring on a 1-inch (25-mm) diameter copper bar a

17、nd circularly magnetize in a standard magnetic particle inspection unit by passing 2500 amperes of direct current through the bar. While the current is flowing, apply approximately 1.0 gram of fresh dry powder that has passed the contamination test, using a suitable squeeze-bulb or shaker applicator

18、. Examine the ring under white light of not less than 100 foot-candles (1000 lx) at the examining surface. SAE INTERNATIONAL AMS3040D Page 3 of 5 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The manufacturer of the product shall supply all samples for manufacturers tests and sha

19、ll be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the product conforms to the specified requirements. 4.2 Classification of Tests All technical requirements are acceptance tests

20、and preproduction tests and shall be performed prior to or on the initial shipment of magnetic particles to a purchaser, on each lot, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing

21、 4.3.1 For Acceptance Tests Sufficient powder shall be taken at random from each lot to perform all required tests. The number of determinations for each requirement shall be as specified in the applicable test procedure or, if not specified therein, not less than three. 4.3.1.1 A lot shall be all p

22、owder produced in a single production run, from the same batch of raw materials under the same fixed conditions, and presented for manufacturers inspection at one time. 4.3.1.2 Sensitivity Test Ring Shall be in accordance with AS5282. 4.3.2 For Preproduction Tests Shall be acceptable to purchaser. 4

23、.4 Approval 4.4.1 Sample powder shall be approved by purchaser before powder for production use is supplied, unless such approval be waived by purchaser. Results of tests on production powder shall be equivalent to those on the approved sample. 4.4.2 Manufacturer shall use ingredients, manufacturing

24、 procedures, processes, and methods of inspection on production powder that are essentially the same as those used on the approved sample. If necessary to make any changes in ingredients, processing techniques, or manufacturing procedures, manufacturer shall submit for reapproval a statement of the

25、proposed changes in ingredients and/or processing and, when requested, sample powder. Production powder shall not be shipped prior to receipt of reapproval. 4.5 Reports The vendor of the product shall furnish with each shipment a report showing the results of tests to determine conformance to the ac

26、ceptance test requirements and stating that the product conforms to the other technical requirements. This report shall include the purchase order number, lot number, AMS3040D, date of manufacture, and quantity. SAE INTERNATIONAL AMS3040D Page 4 of 5 4.6 Resampling and Retesting If any sample used i

27、n the above tests fails to meet the specified requirements, disposition of the product may be based on the results of testing three additional samples for each original nonconforming sample. Failure of any retest sample to meet the specified requirements shall be cause for rejection of the product r

28、epresented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY A lot of magnetic particles may be packaged in small quantities and delivered under the basic lot approval provided lot identification is maintained. 5.1 Packaging and Identification 5.1.1 Dry magnetic particles shall be

29、 in packaged containers of a type and size acceptable to purchaser. 5.1.2 Each package or container shall be legibly identified with a durable label providing not less than the following information: MAGNETIC PARTICLES, NONFLUORESCENT, DRY METHOD AMS3040D COLOR_ MANUFACTURERS IDENTIFICATION_ DATE OF
