DESCRIPTION

BS EN 12664:2001


This standard BS EN 12664:2001 Thermal performance of building materials and products. Determination of thermal resistance by means of guarded hot plate and heat flow meter methods. Dry and moist products of medium and low 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 either in the dry state or conditioned to equilibrium with moist air, having a thermal resistance of not less than 0,1 m2.K/W and a (hygro)thermal transmissivity or thermal conductivity up to 2,0 W/(m.K). (It is expected that the thermal resistance of most masonry specimen will be less than 0,5 m2.K/W).
