SL-L33 Shoe Insulation Testing Machine / Safety Shoes Sole Insulation Testing Machine
Application
This instrument is a testing machine for testing the thermal insulation properties of the whole shoe.
After the sample shoes are placed on a hot plate of a specified temperature for a certain period of time, the temperature rise of the inner surface of the sole is checked.
Standards compliant
ISO-20344
Principle
The sample shoes are placed in a continuously heated sand pool. When the temperature of the sand pool is heated from room temperature to the test temperature, the change of the internal temperature of the sample shoe is recorded, and then the test temperature is maintained, the test is continued until the test time, and then the shoes are inspected.
