Hygrothermal performance of building materials and products - Determination of water absorption coefficient by partial immersion (ISO 15148:2002) EN ISO 15148:2002

Publication date:   Dec 22, 2003

Scope

This standard specifies a method for determining, by partial immersion with no temperature gradient, the short-term liquid water absorption coefficient. It is intended to assess the rate of absorption of water, by capillary action from continuous or driving rain during on site storage or construction, by insulating and other materials, which are normally protected. The method is suitable for renders or coatings tested in conjunction with the substrate on which they are normally mounted.
It is not intended to assess the absorption of water by materials used under water or in overall contact with saturated ground, where a total immersion test is more appropriate.
