TECHNICAL REQUIREMENTS 3.1 Material The product shall be composed of durable fluorescent magnetic particles, suitable for long time use, which have been dyed or otherwise treated to attain the fluorescent color specified.
13、 The particles shall be supplied ready-to-use, mixed in the proper proportion with an inspection vehicle. 3.1.1 Fluorescent particles shall conform to AMS3044. 3.1.2 Magnetic particle inspection vehicle shall conform to AMS2641. 3.2 Storage Life The product shall meet the requirements of 3.3 when te
14、sted 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: 3.3.1 Contamination The product shall show no evidence of foreign matter, a
15、gglomeration, or scum, determined by visual examination of the suspension at the following times: 3.3.1.1 During preparation of the test suspension as in 4.3.3. 3.3.1.2 After mixing the test suspension, allowing it to stand for not less than 30 minutes, and agitating it slightly. 3.3.1.3 During test
16、s to determine conformance with other characteristics of the product. 3.3.2 Concentration The concentration of magnetic particles in the vehicle shall be 0.10 to 0.40 mL of fluorescent particles in 100 mL of suspension, determined by mixing the test suspension thoroughly, filling a 100 mL calibrated
17、 centrifuge tube as specified in ASTM D 1966, allowing it to stand undisturbed for not less than 30 minutes, and reading, on the calibrated tube, the volume of particles settled from the suspension. SAE INTERNATIONAL AMS3045E Page 3 of 5 3.3.3 Sensitivity The product shall provide indications of at
18、least the first seven holes of the test ring specimen of 4.4 when tested as follows: 3.3.3.1 Place 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 current through the copper bar imm
19、ediately before flooding 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 environment under ultraviolet light with a minimum UV-A intensity of 1000 W/cm2at the inspection surface. Visible light shall
20、not exceed 2 foot-candles (20 lx) 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 production inspection. The surface finish of the test specimen shall be representative of production parts
21、. Magnetize and flood the specimen as specified in 3.3.3.1, using a sample of agitated test suspension that has passed the contamination (3.2.1) and concentration (3.3.2) tests. View the flaw indications in a darkened area under backlight as defined in 3.3.3.1. Indications shall be sharp and distinc
22、t. Background fluorescence around the flaws shall be of a level which will neither obscure the flaw indications nor cause difficulty in flaw detection. 4.
