Contact Heat Transmission Test Apparatus

  • ISO 12171-1
  • , EN 702
Contact Heat Transmission Test Apparatus, based on EN 702, specifies a test method of the determination of the contact heat transmission.
It is applicable to protective clothing (including hand protectors) or its constituent materials intended to protect against high contact temperature. The application of the standard is restricted to contact temperatures from 100 °C to 500 °C.​
