--- Remove the appendix about the test data recording table.
Measurement methods in the precious metal thermocouple wire thermal emf.
--- Measurement temperature range of 300 ℃ ~ 1600 ℃;
--- Measuring point temperature to the freezing point of aluminum (660.323 ℃) in place of antimony freezing point (630.63 ℃);
--- B-type thermocouple wire temperature detection point is amended as. 1100 ℃, 1300 ℃, 1500 ℃;
--- Increased S, R, B-type standard grade thermocouple wire temperature detection point and the selection criteria for the corresponding provisions;
--- The high-temperature tube furnace length test is amended as 600mm, mounted on the back of the furnace provided B-type thermocouple wire insertion depth is amended as
300mm;
--- Increased S, R and B grade standard dual wire annealing time and temperature stability.
In the metal thermocouple wire thermal EMF measurement methods.
--- Reference pure platinum wire require modification to its average resistance temperature coefficient in the temperature range of 0 ℃ ~ 100 ℃ should
≥0.003920;
--- Tubular axial test furnace temperature field changed to a uniform temperature on the highest center of the field test and the geometric center of the furnace along the axis should not exceed deviate
10mm, and an increase in provisions radial temperature field;
--- Increasing the detection stage Ⅰ grade thermocouple wire should not be less than first-class standard platinum and rhodium 10 - platinum thermocouple requirements;
--- In tying the request to cancel the provisions of the count, and revised as follows. The total number of thermocouples including standards, that should be tied into bundles to meet
Size and temperature field tubulars test furnace requirement is appropriate.
