Bud, I don't have a copy of the IATA Packing Instruction here at the lab, but from what you described, it may be similar to the "Compass Safe Distance" test which is called out in the Maritime Navigation and Communication EMC Standard EN 60945:1997. This magnetic test determines "the distances above which an equipment will not cause an unacceptable deviation of the ship's standard and steering compasses". The EUT is tested against a compass or magnetometer after magnetization in a specified DC field with a superimposed AC stabilizing field. A baroque-sounding test indeed, but it so happens that a four-foot high by two-foot diameter double-wound solenoid of solid 12-ga copper wire used in the Compass Safe test resides just to the left of my desk here in the lab (only 'cause it's a handy place to store it!). I'd be happy to discuss this test, if it seems relevant. My phone at work is: (360) 595-2785.

My lab has been asked to test our products to the magnetic standards of IATA Packing Instruction 902. This test determines the ability of a device to change a compass reading. I have the regulations and know how to do the test, but do not do it routinely. Products that fail this test must be labeled and additional shipping charges are imposed. I know that one of our products fails and we are labeling it. Fines for non-compliance are substantial, yet I am having a hard time finding anyone who knows about or complies with this standard. My questions are: Does anyone else perform this test, or have it performed on their products? What kind of results are you getting depending upon product size, shape, metal content? Are there exceptions or conditions that would exclude product families from this regulation. Any help or discussion would be appreciated.
