Note: The CGS uniforms in each original position (ST) shall be used (indicated), and the technical requirements of permanent or point-to-point emergency shall be observed
1.! The fast shall meet the requirements of this standard and be manufactured in accordance with the samples approved by the prescribed procedures and technical documents. 4.2 The outer dimensions and the roughness of the surface shall comply with the table! Regulations: Refer to the following table III group planting degree R, 25 mountain 114.3 The shape of the decision should be complete, the edge of the surface, the corners should not damage the price! % 4. The second pole, the 7th surface tolerance is 0.04. The center hole of the delivery block should be standard, and the center axis tolerance is c.5mm4. The center of each core is allowed to have a width of 0.15mm or more, and the average thickness of the new magnet is 13. The length of the crack is not allowed to exceed 14. The total length of the crack shall not exceed 20mm. 4. The non-polar surface of the magnet is not allowed to have a crack greater than 0.15mm or a depth greater than 5mm, and the length of each crack shall not exceed the length of the magnet. 1/2 of the length. Total length of all non-magnetic cracks: the whole piece shall not be greater than 65mm, and the half piece shall not be greater than 35mm. 5 Test method

52 The center sensing piece can be completely accurate G32 is now determined, and a size can be used as required.
JB/T9041—1599
5.3 When using the egg-shaped rapid test method for measurement, the standard sample average value determined by the National Institute of Metrology should be used as the basis for the instrument (mark the maximum magnetic energy product point of the standard sample and calibrate it to the average value. The thickness of the sample to be measured must be the same as that of the standard sample (the inclined magnetic block is used instead of the batch average block for measurement). When measuring the magnetic properties, mark the maximum magnetic energy product point on the sample to be measured. The magnetic properties of this point are the magnetic properties of the sample to be measured. 6 Inspection rules
6.1 Magnetic blocks must be inspected and qualified by the manufacturer's inspection department before they can leave the factory. The manufacturer must have documents proving that the product quality is qualified. 6.2 For the size and appearance quality of the magnetic block, each ball mill or sand mill material is inserted. Each batch of production can be used as an inspection batch, and the inspection can be carried out according to the sampling plan of GB/T2828, where the qualified quality level AQL=4.0 and the inspection level L=1.63. 6.3 The magnetic properties of the magnetic block can be inspected and evaluated by the following method: 1. Each batch of ball mill material or sand mill can can be used as an inspection batch, and the inspection can be carried out according to the sampling plan of GB/T2828, where the qualified quality level AQL=10 and the inspection level L=1.63. b) The magnetic block inspection results are compared with the numerical calibration material brand of Table 2. If one of the performances of B, HcB, (H) does not meet the requirements, the material brand cannot be marked. Marking. Packaging, return and storage
7.1 The packaging mark of the block should include the transport packaging receipt and delivery mark, the packaging storage and transportation graphic mark, and should comply with the provisions of GB/T63 and GB191.
.2 The magnetic block should be shipped in a closed box. The outer wall of the packing box should have obvious words and graphic marks, and comply with the provisions of 7.1, including:
a) The name of the receiving station and the receiving unit:
h) The name of the shipping station and the shipping unit:
e) Contract number and the name and handling number of the block:
d) Weight, net bill, box number and overall dimensions: e) Center of gravity, lifting line, storage and transportation graphic marks. 7.3 The magnetic block should be firmly tied in the box and must not be damaged during transportation. .4 The silicon block after filling should not be close to various instruments, meters and other equipment to prevent being oxidized. In special circumstances, it is necessary to do a good job of shielding. Blocks should be kept in the warehouse and should not come into contact with sexual substances. JR/T9042-1999
