Description

This International Standard specifies methods for the determination of declared and design thermal values for thermally homogeneous building materials and products.

Scope

This International Standard specifies methods for the determination of declared and design thermal values for thermally homogeneous building materials and products.

It also gives procedures to convert values obtained under one set of conditions to those valid for another set of conditions. These procedures are valid for design ambient temperatures between -30°C and +60°C.

Conversion coefficients for temperature, valid for mean temperatures between 0°C and 30°C, and moisture are given in annex A.

This International Standard does not give any conversion coefficients for the effect of ageing or other effects like convection or settlement.
