Shoe heat insulation testing machine -- sand bath
The sand bath component of the shoe heat insulation testing machine is primarily used to test the heat insulation or thermal insulation performance of footwear in a high-temperature sand and gravel thermal medium.
Applications
Shoe heat insulation testing machine - sand bath: This machine is primarily used to test the high-temperature resistance of sole materials such as rubber and polymers used in welding protective shoes and high-temperature shoes. After testing, the surface of the outsole sample should not show any softening, melting, or cracking. The test method involves heating the sand bath to 150℃, covering the contact area between the shoe upper and sole with sand, and recording the change in insole temperature over 30 minutes, with an accuracy of 0.5℃.
Standards
GB/T 20991: Determines thermal insulation of safety shoe soles under simulated hot surface exposure.
EN ISO 20344: European standard for personal protective equipment (PPE) footwear thermal resistance testing.

Test Procedures
Calibration Procedure:
Calibration Item: Temperature
Calibration Instrument: Surface Thermometer
Calibration Period: One year
Calibration Method:
1. Turn on the power switch and set any test temperature on the temperature controller (e.g., 40℃, 60℃, 80℃).
2. Place the surface thermometer's sensing probe on the machine's heating plate and turn on the surface thermometer's power switch to allow the machine to heat up.
3. When the test machine (i.e., the displayed value of the temperature controller) reaches the set test temperature, observe the difference between the displayed value of the surface thermometer and the displayed value of the temperature controller.
