I routinely test all our products to the IATA requirements. There are no
exemptions the regulations apply to all goods put onto an aircraft.
In general I find products which have welded steel are going to produce a
magnetic field. With the field most concentrated at the weld points. If it is a
rack, it almost always needs to be labelled. Aluminium bodies and riveted
construction tends not to be too magnetic and can often go unlabelled. Although
on occasion have found fields coming from large sheets of rolled steel.
Basically if the product has a lot of ferromagnetic material, it can become
magnetised during construction. Also watch out for large coils and
transformers, magnetising the surrounding materials.
If you are having trouble locating information on IATA testing, I suggest you
try the FAA. They enforce the IATA regs within US airspace.

Subject: IATA 902 Magnetic Testing
Although this is not an EMC standard it is related. 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.
