BS EN ISO 23993:2010

This standard BS EN ISO 23993:2010 Thermal insulation products for building equipment and industrial installations. Determination of design thermal conductivity is classified in these ICS categories:

• 91.100.60 Thermal and sound insulating materials
• 27.220 Heat recovery. Thermal insulation
• 91.120.10 Thermal insulation of buildings

This International Standard gives methods to calculate design thermal conductivities from declared thermal conductivities for the calculation of the thermal performance of building equipment and industrial installations.

These methods are valid for operating temperatures from -200 °C to +800 °C.

The conversion factors, established for the different influences, are valid for the temperature ranges indicated in the relevant clauses or annexes.
