ISO 8302 Thermal Insulation - Determination of Steady-State Heat Resistance and Related Properties - First Edition of the Shielded Hot Plate Apparatus

The ISO 8302 standard, developed by the International Standards Organization (ISO), introduces a test method that describes the use of the shielded hot plate method to measure steady-state heat transfer through flat plate samples and calculation of heat transfer properties.

ISO 8302 Thermal Insulation - Determination of Steady-State Heat Resistance and Related Properties - First Edition of the Shielded Hot Plate Apparatus

This is an absolute or primary method of measuring heat transfer properties because only measurements of length, temperature and electrical power are required.

Reports conforming to this standard test method may never refer to specimens with a thermal resistance less than 0,1 m²⋅K/W, provided the thickness limits are not exceeded.

The thermal resistance limit can be as low as 0,02 m2 · K/W but the specified accuracy may not be achieved over the full range.

If the samples only meet the specified requirements, the resulting properties will be defined as the thermal conductivity and thermal resistance or transfer factor of the sample.

If the samples meet their requirements, the resulting property can be defined as the average measurable thermal conductivity of the sample under consideration.

If the samples meet their requirements, the resulting property can be defined as the thermal conductivity or transferability of the material under consideration.

Among the services provided by our organization within the framework of material testing services, there are also ISO 8302 standard tests.
