TECHNICAL REQUIREMENTS 3.1 Material The product shall be composed of durable fluorescent magnetic particles, which have been dyed or
13、otherwise treated to attain the color specified. The particles shall be supplied mixed in the proper proportion with an inspection vehicle and packaged in aerosol cans. 3.1.1 Fluorescent magnetic particles shall conform to AMS3044. 3.1.2 Magnetic particle inspection vehicle shall conform to AMS2641.
14、 3.2 Storage Life The product shall meet the requirements of 3.3 when tested at any time up to 12 months from date of manufacture. 3.3 Properties The product shall conform to the following requirements; tests shall be performed on the product supplied in accordance with specified test methods, using
15、 a test suspension prepared by spraying the complete contents of several aerosol cans into a clean container to produce at least 1 quart (1 L) of suspension, agitating the aerosol cans frequently to exhaust all particulate material: 3.3.1 Contamination The product shall show no evidence of foreign m
16、aterial, agglomeration, or scum, determined by visual examination of the test suspension at the following times: 3.3.1.1 During preparation of the test suspension as in 3.3. 3.3.1.2 After mixing the test suspension, allowing it to stand for not less than 30 minutes, and agitating it slightly. 3.3.1.
17、3 During tests to determine other characteristics of the product. _ SAE INTERNATIONAL AMS3046F Page 2 of 63.3.2 Concentration The concentration of fluorescent magnetic particles in the freshly-sprayed suspension shall be 0.15 to 0.30 mL of fluorescent magnetic particles in 100 mL of suspension, dete
18、rmined by mixing the test suspension thoroughly, filling a 100 mL calibrated centrifuge tube as specified in ASTM D 1966, allowing it to stand undisturbed for at least 30 minutes, and reading, on the calibrated tube, the volume of the particles settled from the suspension. 3.3.3 Sensitivity 3.3.3.1
19、Ring Test The product shall provide a seven-hole indication on the ring test specimen defined in AS5282, determined by placing the ring on a 1-inch (25-mm) diameter copper bar and circularly magnetizing the ring in a standard magnetic particle inspection unit by passing 2500 amperes of direct curren
20、t through the bar immediately before flushing the ring with the agitated test suspension that has passed the contamination (3.3.1) and concentration (3.3.2) tests. Examine the ring in a darkened area under UV-A illumination of at least 1000 W/cm2at the inspection surface. Visible light shall not exc
21、eed 2 foot-candles (20 lux) at the inspection surface. 3.3.3.2 Flaw-to-Background Test Obtain a test part, or prepare a test specimen, containing flaws of the size expected to be found in routine inspection. The surface finish of the test specimen shall be representative of production parts. Magneti
22、ze and flush the specimen as specified in 3.3.3.1, using a sample of agitated test suspension that has passed the contamination (3.3.1) and concentration (3.3.2) tests. View the flaw indications in a darkened area under ultraviolet light as defined in 3.3.3.1. Indications shall be sharp and distinct
23、. Background fluorescence around the flaws shall be of a level which will neither obscure the flaw indications nor cause difficulty in flaw detection. 3.4 Aerosol Spray Cans The aerosol cans selected for test shall be maintained at room temperature for not less than 12 hours prior to testing. During
24、 testing, the aerosol can may be immersed in water at 77 F 2 (25 C 1) periodically to maintain the container and its contents at room temperature. 3.4.1 Sprayability and Leakage 3.4.1.1 All aerosol pressure cans shall be equipped with a spray nozzle. The nozzle shall provide a fine, steady spray and
25、 shall deposit the product evenly on a flat or vertical surface. No chunks of solids shall be expelled and no clogging of the nozzle shall occur. 3.4.1.2 The characteristics of the spray pattern and the performance of the spray nozzle shall be evaluated by vigorously shaking the can for not less tha
26、n 30 seconds with the contained pellet sounding on each shake and spraying a pattern on large sheets of newspaper or a similar surface to determine the coverage and evenness of the spray. After spraying several patterns, the nozzle shall be examined for evidence of chunks or solids and clogging. The
27、 can shall then be immersed for not less than 15 minutes in water at 126 to 129 F (52 to 54 F); there shall be no visible evidence of leakage from, or distortion of, the pressurized container. The pressurized can shall then be immersed in water at 77 F 2 (25 C 1) until the temperature has stabilized
28、 and, after vigorous shaking, two more patterns shall be sprayed. The spray characteristics shall have not changed and there shall be no chunking of particles or clogging of the nozzle. 3.4.1.2.1 CAUTION: DO NOT HEAT THE PRESSURIZED CAN OVER 129 F (54 C). _ SAE INTERNATIONAL AMS3046F Page 3 of 63.4.
29、2 Complete Expulsion The complete usable portion of the contents shall have been expelled before the propellant is expended. The expelled contents shall be not less than 5 fluid ounces (50 mL) and the particle content shall conform to the aerosol spray requirements. Vigorously shake for not less tha
30、n 30 seconds each unused can to be tested, with the contained pellet sounding on each shake, and expel the contents in a series of short blasts into a clean glass container graduated in ounces (mL) in such a manner that the entire contents of the can will be retained in the glass container. The aero
31、sol can may be immersed periodically in water at 77 F 2 (25 C 1) to maintain the can and its contents at room temperature. Repeat the vigorous shaking and short blasts until there is no further escape of gas. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the product
32、 shall supply all samples for vendors tests and shall be responsible for the performance of all required tests.
