Thermal insulation products for building equipment and industrial installations. Determination of declared thermal conductivity1 Scope This standard establishes the procedure for the determination and verification of the declared thermal conductivity as a function of temperature of thermal insulating materials and products used for the insulation of building equipment and industrial installations. The informative annex B also gives an optional method for establishing the thermal conductivity curve or table from measured values. The standard is not applicable to thermal
