Standards

  • EN 12667 - Thermal performance of building materials and products - Determination of thermal resistance by means of guarded hot plate and heat flow meter methods - Products of high and medium thermal resistance
  •  ASTM C518 - Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus

  • EN 13162 to 13171 – Product Standards of thermal insulation products for buildings
  • EN 16012 - Thermal insulation for buildings - Reflective insulation products - Determination of the declared thermal performance

Principle

A test specimen is placed between a hot and a cold plate. The heat flow through the test specimen to maintain the temperature difference at a constant level is a measure of the thermal resistance / conductivity (insulation) of the test specimen.
