BS EN 12667:2001

This standard BS EN 12667:2001 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 is classified in these ICS categories:

• 91.100.01 Construction materials in general
• 91.120.10 Thermal insulation of buildings

This standard specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of test specimens having a thermal resistance of not less than 0,5 m2 K/W.
