This standard refers to GB/3 772-1983 is a revision of 10-platinum thermocouple and graduation table 3. The technical standard and 77133 are referred to as the original standard below: 1. The original standard adopts the IPTS-G product standard. This standard adopts the I1S-90 temperature standard. All internal thermoelectric potential values have been revised. 2. The original standard contains the graduation table of thermocouples. Since there is a national standard for thermoelectric graduation table, the thermocouple graduation table cannot be listed in this standard. This standard lists the thermal conductivity values and specifications of thermocouples at the working temperature points to facilitate the inspection. 3. The original standard only regulates industrial thermocouples, and the technical standard only adds the standard thermoelectric wire. This standard makes a textual modification to the original standard according to the requirements of GB/T1.1-933 and GB/T1.22-1S3. This standard shall replace E/T3772-1963 from the date of approval. This appendix is an appendix to the standard.

11- 957 Type inspection
All test items of this standard should be carried out immediately. There are one of the following situations, generally the type inspection is carried out immediately: a) new products or standard products are transferred to the factory for production and testing; b) after normal production, such as when the raw materials and process are greatly reduced; d) when the product is stopped for a long time and then restarted; e) when the factory inspection results are significantly different from the last type inspection results, the requirements for retroactive type inspection are reduced. 7.2 Detailed sampling
7.2.1 Factory inspection type inspection is carried out from the production of each parameter (plate) to the head and tail of the wire. The two ends are about 1m for inspection. The high gauge pressure measuring scale should be used for the whole (coil> false wire test.
7.2.2 Only the qualified products of the type are randomly selected from the load-bearing even wire of not less than 3 rolls (), and the even wire (coil) should be 4

newly collected 1.1m and the other full collected 3.51 month small work will not be about the heat electric test. The remaining appropriate wire head is taken for inspection, but the table and the standard seat and the inch item 7.31 Inspection data should be sent out, if there is one unqualified item, the product will be scanned and packaged one by one: the product is unqualified 7.32 When the type support is inspected, if there is still one unqualified item, it should be doubled and re-inspected. If there is still one unqualified item, it will be judged as unqualified for type inspection:
supplier or packaging and marking
8.1 Supply method
Supply according to the hardening state of the wire. Each belt needs a wire pad, root wire Wind it and there will be no joint in the middle. Its weight is not less than 1Cg. If it is needed, please provide small 10C borrowed wire. 6.2 Packaging
The wire is rolled or washed online in the main coil, and the diameter of the coil is about 1. The wire should be tied at two places to help the whole cable. The terminal end on the coil should be firmly fixed. The material should be well packed. 8.3 Cooperation
8.3.1 Over-coil (the coil may be marked with
