6 EN :2011 (E) 1 Scope This European Standard specifies a method of determining the water absorption of clay and calcium silicate masonry units by immersing them in cold water. 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. EN 771-1, Specification for masonry units Part 1: Clay masonry units EN 771-2, Specification for masonry units Part 2: Calcium silicate masonry units EN 771-3, Specification for masonry units Part 3: Aggregate concrete masonry units (Dense and lightweight aggregates) EN 771-4, Specification for masonry units Part 4: Autoclaved aerated concrete masonry units EN 771-5, Specification for masonry units Part 5: Manufactured stone masonry units EN 771-6, Specification for masonry units Part 6: Natural stone masonry units 3 Principle After drying to constant mass a masonry unit is immersed in water for 24 h and the increase in mass is determined. 4 Symbols M d is the mass of the specimen after drying (g); M s is the mass of the specimen after soaking (g); W s is the water absorption of the specimen (%). 5 Apparatus 5.1 Water tank large enough to contain all of the samples, supported off the base of the tank so that water is in contact with all the faces of the specimen. 5.2 Ventilated oven capable of maintaining a temperature of 105 C + 5 C. 5.3 Weighing instrument capable of weighing the specimens to an accuracy of 0,1 % of their mass when dry. 4
