DeltaFlux DF S 90 AS 5282 Magnetic Particle Test Ring

The DeltaFlux DF S 90 is an AS 5282 test ring that gives a quick way to confirm your DC-output magnetic particle machine works properly. The ring has pre-drilled holes simulating subsurface defects. Processed with the continuous method, indications of these artificial defects form on the surface; their number shows the performance of the magnetising current and the testing medium.

Key features

• System performance test: verifies bench, current and particle medium together
• Quantitative: a minimum number of holes is defined for each current level
• Standards: ASTM E709, ASTM E1444/E1444M, ASTM E3024/E3024M, ASME Boiler & Pressure Vessel Code, SAE AS 5282
• Trend tracking: benchmarking each ring and bench combination reveals any drop in performance early

Technical specifications

• Use: On a non-ferromagnetic central conductor (1″–1¼”, 25.4–31.75 mm), circular magnetisation with a head shot, continuous method
• Fluorescent oxide (wet): 500 A: 3 · 1000 A: 5 · 1500 A: 6 · 2500 A: 7 · 3500 A: 9 holes (minimum)
• Visible oxide (wet): 500 A: 3 · 1000 A: 4 · 1500 A: 5 · 2500 A: 6 · 3500 A: 8 holes (minimum)
