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, flling a 100 mL graduated, calibrated, pear shaped centrifuge tube as specified in ASTM E709, 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.
Prepare a test specimen meeting the requirements of Figure 1. The test specimen consists of SAE 4130 (AMS6350) or SAE 4340 (AMS6359) steel heat treated to 180 ksi with surface finish 16 microinch (0.4 micrometers) or better. The specimen contains a single fatigue crack (0. 100 to 0.250 inch surface length) grown using 3-point bending. Magnetize and flush the specimen using a sample of agitated test suspension that has that has passed the contamination (3.3.1) and concentration (3.3.2) tests. Using the wet-continuous method, longitudinally magnetize the specimen in an alternating current (AC) field to achieve 30 to 60 gauss tangential field measured in accordance with ASTM E709. View the crack indication in a darkened area under UV-A as defined in 3.3.3.1. Indication shall be sharp and distinct. Background fluorescence around the indication shall be of a level which will neither obscure the indication nor cause difficulty in flaw detection. See Figure 2 for an example indication.
Prepare a test specimen meeting the requirements of Figure 3. The shim test specimen consists of SAE 4130 (AMS6350) or SAE 4340 (AMS6359) steel heat treated to 180 ksi with surface finish 16 microinch (0.4 micrometers) or better. A type 3C2-234 shim conforming to AS5371 is epoxied to the center of the specimen with notches facing down. Magnetize and flush the specimen using a sample of agitated test suspension that has that has passed the contamination (3.3.1) and concentration (3.3.2) tests. Using the wet-continuous method, longitudinally magnetize the specimen in an alternating current (AC) field to achieve 30 to 60 gauss tangential field measured in accordance with ASTM E709. View the flaw indications in a darkened area under UV-A as defined in 3.3.3.1. All three ring Indications shall be sharp and distinct. Background fluorescence around the flaws shall be of a level which will neither obscure the flaw indications nor cause difficulty in flaw detection. See Figure 4 for an example indication.SAE AMS 3045F pdf free download.
