Q: Why are some air cargo magnetized? A: magnetic cargo is classified as category 9 dangerous goods by IATA and must be restricted at the time of shipment because of the interference of weak stray magnetic fields on the aircraft's navigation systems and control signals. So now some air cargo with magnetic materials are required to carry out magnetic detection, in order to ensure the normal flight of aircraft. Q: Technical Requirements for magnetic testing of air cargo? A: in accordance with the relevant IATA DGR provisions, if the maximum magnetic field strength of any substance packaged for air transport is less than 0.159 A/M (200 NT) at a distance of 2.1 m (7 ft) from any point on the outer surface of the package, the article is not restricted as a magnetic material and can be shipped as a general cargo. Q: is magnetic testing degaussing? A: magnetic detection is to detect the magnetic size of the cargo at a distance, not to remove the magnetic properties of the cargo. Q: does magnetic inspection require unpacking? A: magnetic testing requires customers to air transport requirements of the goods packed, testing will not damage the packaging of the goods. In principle, the detection process is not to open the cargo, but to each of the 6 surfaces of the cargo stray magnetic field detection.
Q: What if the goods fail the inspection? A: if the magnetic inspection of the goods is not satisfactory and the technical services of the testing party are required, the staff member will open the goods at the request of the client and make the relevant reasonable recommendations according to the specific circumstances. If the shielding can meet the requirements of air transport, the client can be entrusted to shield the goods, and charges related fees. Q: does the shielding provided have an impact on product performance? A: the shielding provided by the testing company does not remove the magnetism of the goods with magnetic field exceeding the standard. It has little effect on the performance of the products, but it will communicate with the customers in detail so as to avoid causing losses to the customers. Conditional customers can also take back the goods after their own handling good again for inspection. Q: if the shielding doesn't work, how can we export the goods? A: according to IATA DGR packing instruction 902: if the maximum magnetic field strength exceeds 0.159 A/M (200 NT) at a distance of 2.1 m (7 ft) from the surface of the object under test, but the arbitrary magnetic field strength at a distance of 4.6 m (15 ft) from the surface of the object under test is less than 0.418 A/M (525 NT) , the goods may be received and shipped as dangerous goods. If this requirement can not be met, then the goods can not be transported by air. You may entrust the goods to sea.
Q: need magnetic inspection of goods a: common goods need to do magnetic inspection: magnets, magnetic blocks, magnetic strips and a series of magnetic materials manufacturing products. For example, common audio, microphones, and so on, including electrical, mechanical goods or with magnetic are required to do magnetic inspection. 1) magnetic material, magnet, magnet, magnet steel, magnetic nail, magnetic head, magnetic strip, magnetic disc, magnetic block, ferrite core, al-ni-co, electromagnet, magnetic fluid seal ring, ferrite, oil-cut electromagnet, rare earth permanent magnet (motor rotor) . 2) sound equipment, speakers, speakers, speaker speakers/speakers, multimedia speakers, speakers, cds, cassette recorders, mini sound combinations, speaker accessories, microphones, car horns, microphones, receivers, buzzers, silencers, projectors, loudspeakers, VCD, DVD. 3) other, hair dryer, TV, mobile phone, motor, motor accessories, toy magnets, magnetic toy parts, magnetic health pillow, magnetic health products, compass, car inflatable pump, driver, reducer, rotating parts, inductor components, magnetic coil sensor, electric gear, relay, multimeter, magnetron, computer and accessories.
