EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 772-7 testing. This European Standard specifies a method for determining the water absorption of moisture-resistant clay masonry units by boiling samples in water for a fixed period of time.
The samples are weighed after drying to constant mass and then immersed in boiled water for 5 hours, wiped and weighed. The ratio of the increase in mass of saturated samples to the dry mass is calculated.
The standard details the boiling method to determine the water absorption rates of these units. This method involves boiling the units for a specified time and temperature and then calculating the amount of water absorption.
Sample units are first weighed to determine their dry weight. Next, the units are kept in boiling water for a certain period of time. This process allows the units to absorb water. After the boiling process, the wet weights of the units are measured.
The water absorption rate is determined by calculating the wet weight increase as a percentage of the dry weight of the units. Water absorption testing plays an important role in evaluating the quality and performance of clay masonry damp proof course units. The results of this testing are used to determine how effective these units are in controlling humidity.
EN 772-7 provides a standard method for determining the water absorption rates of clay masonry damp-proof course units, thus ensuring comparability between products from different manufacturers.
