Air super magnet what request for packing?

1. Permanent magnet materials must be equipped with retentivity armature to shield, or in case of magnetic compass deviation instrument. 2. Magnetic material of each package must be in accordance with chapter 7 of the rules of iata dangerous goods correct marking, and labeling. 3. Make sure before shipment, from 4 on the surface of the packaging. 6 m ( 15 feet) The measured magnetic field strength is less than 0. 418 / m ( 00525 gauss) 。 Above when magnetic material as a dangerous goods inspection standard, the domestic customer to magnetic materials as non-dangerous goods for air shipment, the shielding requirements: 4. Need to make sure before shipment, is apart from the 2 on the surface of the packaging. 7 meters measured magnetic field strength less than 200 nt ( Is equal to 2 the MGS = 0. 002Gs) 。 5. As far as possible in order to ensure the gauss meter measuring accuracy and ensure that is not affected by the earth's magnetic field, general advising clients in the distance on the surface of the packaging is 0. 5 meters to measure, according to the theoretical calculation & lsquo; Is inversely proportional to the square of the distance from magnetic field strength & rsquo; The closer is the distance measured by magnetic field intensity. For example: 2. 7 meters measuring magnetic field size of 0. 002 gs, follow & lsquo; Is inversely proportional to the square of the distance from magnetic field strength & rsquo; The theory formula in the distance on the surface of the packaging strictly 0. 5 meters to measure the size of the magnetic field should be 0. 05832Gs。 Distance by 5. Four times, that is, field size 29. 16 times. 6. Case: customers in the production of a batch of N35 types of powerful magnets but cannot transport, because can not meet the packaging requirements of the international association for the airline. 7. Magnets by air Courier, objects are defined as dangerous goods, export difficulties. 8. But the delivery date is coming soon, actually can solve this problem completely, is Hong Kong DHL. 9. From a third party transit transshipment in Hong Kong DHL, seemingly can completely solve the problem, and it takes in accordance with the requirements for magnetic separation packaging. www。 yirongciye。 com
