: Variations in brick manufacturing can compromise load-bearing masonry structures.

Part 1 focuses specifically on the . It sets out the laboratory procedures required to ensure that brick manufacturers, developers, and engineers are calculating strength in a consistent, reliable manner. Scope of the Standard

Compressive strength of bricks, concrete blocks, and other masonry units. bs en 7721 pdf

is the official British and European standard used to determine the compressive strength of masonry units , including clay bricks, aggregate concrete blocks, autoclaved aerated concrete (AAC), manufactured stone, and natural stone. The current active version of this harmonized standard is BS EN 772-1:2011+A1:2015 . It provides structural engineers, manufacturers, and testing laboratories with a unified methodology to evaluate whether materials can safely bear structural loads.

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:
