The shipper shall comply with IATA Packing Instruction 902 and the following requirements:
To prevent interference with aircraft instruments, especially compass instruments, shippers should package magnetic materials in the following manner:
1 The opposite magnetic poles of instruments and devices such as magnetrons and illuminometers must be placed opposite each other.
2 The permanent magnet material must be equipped with a magnetically-loaded armature or a screen to prevent the magnetic field from causing deviation of the compass meter.
3 Each package of magnetic material must be properly marked and labeled in accordance with the provisions of Chapter 7 of the IATA Dangerous Goods Regulations.
4 Ensure that the magnetic field strength measured at 4.6 m (15 ft) from the surface of the package is not exceeded before the shipment is checked.
0.418A/m (0.00525 Gauss).
The above is the test standard for magnetic materials as dangerous goods. Domestic customers use magnetic materials as non-dangerous goods for air transportation. The shielding requirements need to ensure that the measurement is 2.7 meters away from the surface of the package before the goods are checked. The magnetic field strength does not exceed 200 nT (ie equal to 2 mGs = 0.002 Gs).
The company's HT203 digital Gauss meter is designed to ensure the measurement accuracy and to ensure that it is not affected by the geomagnetic field. It is generally recommended that the customer measure at a distance of 0.5 m from the surface of the package. According to the theory, the square of the distance is inversely proportional to the magnetic field strength. The closer the measured magnetic field strength is. For example, the magnetic field is measured at 2.7 meters and the magnetic field is 0.002 Gs. According to the theoretical formula of 'the square of the distance is inversely proportional to the magnetic field strength', it is strictly measured at a distance of 0.5 m from the surface of the package. The size of the magnetic field should be 0.05832 Gs. . The distance is shortened by 5.4 times, that is, the magnetic field is enlarged by 29.16 times.
Case: The customer produces a small number of small magnets (magnets) of the N35 model but cannot be transported by many parties. Because it does not meet the packaging requirements of the International Aviation Association. The magnets are transported by air and express. Items are defined as dangerous goods. and so. Quite difficult to export. But the delivery date is coming soon. and so. There is such a problem. In fact, it can be solved completely. Just take the DHL Express.
DHL, which transits from a third party to Hong Kong, can completely solve this problem. The goods are shipped from Shenzhen Port to Hong Kong. Super trunk. Time to arrive in Hong Kong one day. After arriving in Hong Kong. DHL's agent channel can be arranged. Normal transfer. The procedure only needs to be packaged and magnetically separated.
