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.
Features
Sand Bath System:
Heated Plate: 300mm × 300mm aluminum plate with 50mm silica sand layer.
Uniform Heating: Embedded cartridge heaters with thermal diffusers.
Temperature Control:
PID controller with auto-tuning for rapid setpoint convergence.
Over-temperature alarm with 5°C differential protection.
Sensing Suite:
2 × K-type thermocouples for sand bath and shoe interior.
1.5m cable length for flexible probe placement.
Safety Systems:
Category II electrical safety certification (EN 60529).
Residual current device (RCD) for operator protection.
Software Bundle:
ThermShoe Pro™: Auto-calculates thermal gradient (°C/min) and insulation index.
Cloud PPE: Remote monitoring for global R&D teams.
