Safety Shoes Cold Insulation Test Chamber GT-KB25
Application
To determine the Cold insulation test for safety shoes under low-temperature.
Test Method
- 1.Adjust the temperature of the cold box to (–17 ± 2) ℃ and maintain this temperature during the test.
- 2.Place the test piece on the laboratory jack inside the cold box.
- 3.Use the temperature measuring device connected to the temperature probe to measure the temperature on the insole as a function of time, recording the temperature decrease graphically.
- 4.Calculate, to the nearest 0,5°C, the decrease in temperature 30 min after the test piece was placed in the cold box.
