This European Standard specifies equipment and procedures to condition a thermal insulating product to equilibrium moisture content at (23 +- 2 C) and (50 +- 5) % relative humidity. The standard is also applicable to thermal insulating products with moulded skins but is not normally relevant for faced products or for products with other surface treatments.
NOTE 1 : The normally specified moisture content is the result of the
equilibrium between the atmosphere and the product at (23 +- 2) C and (50 +- 5) % relative
humidity. The standard may also be used if a product has to be conditioned to other relative humidities.
NOTE 2: The moisture equilibrium may - due to hysteresis effects - differ depending on whether the equilibrium has been reached by absorption or by desorption. In addition perfect equilibrium may require a very long time to be reached. Therefore it is necessary to accept equilibrium within a certain accuracy.
NOTE 3: For products which do not absorb moisture, conditioning is not needed. It should nevertheless be ensured that there is no water on the surface before testing.
