The unique identification and description of the masonry units.
Masonry construction remains a cornerstone of the building industry, providing structural integrity, durability, and aesthetic value. To ensure that masonry units—such as bricks, blocks, and stone—can withstand the immense vertical loads applied to them, stringent testing methods are required.
Units are saturated in water, which often results in a lower measured strength compared to dry states. 4. Results and Normalisation

The loading faces of the specimens must be completely flat and parallel to ensure even load distribution during testing. If the surfaces are irregular, frogged, or perforated, preparation is required using one of the following methods:
Meets the requirements of European and British building regulations. Units are saturated in water, which often results
Machining the surfaces until they meet flatness tolerances.
Manufacturers use this standard to verify the quality and reliability of their products. Where to Find the BS EN 772-1 PDF
Specimens may need to be conditioned by drying or by being brought to a specific moisture content to ensure consistent results.
