EN 15801:2009 (E) 4 Introduction This test method can be applied if it does not change the value of the cultural property and follows relevant ethical codes of conservation practice. SIST EN 15801:2010



EN 15801:2009 (E) 5 1 Scope This European Standard specifies a method for determining the water absorption by capillarity of porous inorganic materials used for and constituting cultural property. The method may be applied to porous inorganic materials either untreated or subjected to any treatment or ageing. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. prEN 15898:2009, Conservation of cultural property — Main general terms and definitions concerning conservation of cultural property 3 Terms and definitions For the purposes of this document, the terms and definitions given in prEN 15898:2009 and the following apply. 3.1 porous inorganic materials materials including natural stones, e.g. sandstone, limestone, marble, as well as artificial materials, such as mortar, plaster, brick and others 4 Principle Determination of the amount and rate at which a specimen absorbs water by capillarity through the test surface when it is in contact with water. 5 Symbols and abbreviations For the purposes of this document, the following symbols and abbreviations apply: m0

mass of the specimen at time ti, in kg A
area of the specimen in contact with water, in m2 ti time elapsed from the beginning of the test, in s Qi water absorbed per unit area, in kg/m2 AC capillary water absorption coefficient, in kg/(m2·s1/2) Hi height of the front of water, in cm B capillary water penetration coefficient, in cm/s1/2 SIST EN 15801:2010
