YS/T=66—2003
This standard uses the method of heat treatment under different conditions to evaluate the heat resistance of the belt structure. This standard allows the silver belt to be treated under specific conditions of heat treatment temperature and filtration. This standard is approved by the National Nonferrous Metals Association and the National Nonferrous Metals Association. The standard is planned and initiated by Luoyang Copper Second Group Co., Ltd., and the six main persons in charge of the standard are: Dao Hongdong, Xu Xiangjiao, Lu Junpan, Ying Zuohua, Dao Hengxian Standard Technical Committee.

7.3.1 Original hardness test of the sample
For the original hardness test that has not been heated, or the test method is connected to B/4340, 1 environment is determined, and each test object is observed at five points.
1.3.2 Residual hardness test of the sample
7.3.2.1 Take out the heat-resistant test sample, and cold-print the single window source. The test sample has obvious oxidation color and is effectively treated. When light treatment is adopted, the polishing requirements and requirements of YS44S2002 Section 5.2 shall be followed. After polishing, the thickness of the test mold shall be less than 5 grams. 3.2.2 For the specimen according to G/T130, the reduction test shall be carried out. The five-point hardness test shall be carried out on each specimen. 7.3.3 Hardness treatment shall be carried out by changing the original test points according to the detailed reasoning. The total hardness shall be reduced and the lowest point shall be obtained. The test results are shown in Table 1: 8.1 Softening characteristic curve The mold can be heated to a temperature of 100 °C. The test speed curve will be drawn as the coordinates of the test column. See Figure 1.150 for an example. () Ju: 1. The following is a sample curve. The sample is heated at a specified temperature and the softening temperature is the same as the softening temperature. Figure 1 Softening characteristic curve example 8.2 is the final judgment. YS/T 466-7003. When the sample is tested by the wood method under the specified heating temperature and salt preservation conditions, the residual hardness value of the sample at the end of the heating is used as the final result of the test.
