BS EN 772-10:1999 PDF Download

BS EN 772-10:1999 is a standard that provides methods for testing masonry units, specifically for determining the moisture content of calcium silicate and autoclaved aerated concrete units. The standard outlines a procedure where the units are dried to a constant mass and then the ratio of the loss in mass during drying is calculated in relation to the mass after drying.

The purpose of this standard is to ensure accurate and consistent measurements of moisture content in these types of masonry units. By determining the moisture content, it allows for evaluation of the unit's suitability for use in construction applications, as excessive moisture can affect the performance and durability of the units.

The method described in the standard involves subjecting the units to a controlled drying process until a constant mass is achieved. This constant mass is then used as a reference point for calculating the moisture content. The ratio of the loss in mass during drying, compared to the mass after drying, provides an indication of the moisture content of the units.
