This standard is equivalent to 81:1595 Thermoelectric value dividing meter>Medium K type thermoelectric value dividing meter machine IEC58+2198 Thermoelectric value dividing meter Part 1>Medium K type thermocouple filling benzene. This standard certifies that the lower type of thermocouple wire has a higher penetration rate. The main differences between this standard and 1EC5%121989 are: the temperature range of type K thermocouple in this standard is 130C~200C, while that of 581-2 is -4℃~200. This standard is based on G82614--1935 thermocouple wire and tapping table 3. The main differences between this standard and GTL/T2614198 (hereinafter referred to as the original standard) are as follows: 1 The original standard adopted TPTS·58, while this standard adopts TITS-S standard. All electromotive force values have been corrected.
2 The original standard contains the thermocouple table, but there is a thermocouple table in the country. The thermocouple table is not listed in this standard: However, this standard gives the thermoelectric potential value and the difference at the main temperature point of the thermocouple to facilitate the inspection of the couple wire: 3 The original standard technical requirements 4 H include the chemical composition of the wire, and require inspection. The technical standard only lists the nominal chemical composition in the product classification-competition, and does not require inspection.
4 The standard report was edited according to GB 1.11D93 and GB/T 1.221993, and the text 1 was modified. This standard will replace GB/T 2514-10 from the date of implementation. Appendix A of this standard is a supplement to the standard.
This standard is proposed by the Machinery Industry of the People's Republic of China. It is under the jurisdiction of the Instrument and Energy Materials Standardization Technical Committee of the Ministry of Machinery Industry of the People's Republic of China. This standard was drafted by the Ministry of Machinery Industry, including the Ministry of Industry and Information Technology, Shenyang Hehui Section Co., Ltd., Wujin Fang Electronic Alloy Material Factory, Tianjin Deyou Kezhi Group Co., Ltd., Wujin Yuanle Instrument Material Co., Ltd. and other single-signed information. The principal authors of this standard are Zhang Zelin, Jiang Lixin, Zhu Chiyin, Xu Yonghong, Zhang Xiaobi and Yuan Hongyi. This standard was first issued in March 1981 and first revised in March 1985.

6.5 Migration test
For this test,
will be combined with the second-class standard platinum energy 10-platinum thermal tester (the standard tester is equipped with a high-value lead tube and put into the test tube. The test sample is inserted into the test tube to a depth of not less than 3 cm. After the temperature rises to the specified value, start measuring its thermoelectric potential, and measure it every hour. When the change of its thermoelectric potential value is within the specified range of V, the obtained value shall be taken as the total measured value E. At the same time, record the time and make the starting time of the step-by-step migration test. , and monitor the thermal electromotive force every hour. Within 200h, the measured thermal electromotive force value E is compared with the overall value 6=2, which is the period of qualitative compensation.
7.1 Inspection classification
