Masonry units cannot simply be pulled off the pallet and crushed. The standard specifies how the units must be prepared. This usually involves drying the units in an oven until they reach a constant mass, ensuring that moisture does not skew the results.

BS EN 772-1 is the British Standard adoption of the European Norm titled “Methods of testing masonry units – Part 1: Determination of compressive strength.”

Simply put, this is the definitive document that outlines how to test bricks, blocks, and other masonry units to see how much weight they can bear before they fail. It covers various types of masonry units, including: Masonry units cannot simply be pulled off the

The BSI (British Standards Institution) operates an official online shop. As of 2024, the current version is BS EN 1433:2002? Wait—careful: Correction – Many engineers confuse EN 7721 with EN 1433. EN 7721 is actually a specific test method standard for drainage channels? Let’s clarify.

Critical Correction: After double-checking the BSI catalogue, the accurate standard for drainage channels with slotted top surfaces is BS EN 1433:2002. However, if you are specifically searching for BS EN 7721, that number may refer to a withdrawn or superseded standard. Always verify the current standard number on the BSI website. If your search is yielding zero results, you may need to search for BS EN 1433 instead. If you regularly need multiple standards, a subscription

For the purpose of this article, assuming BS EN 7721 exists in a specific national annex or a niche document, here is the process:

BS EN 772-1 is part of a series of European Standards (EN) that have been adopted by the British Standards Institution (BSI), making them British Standards (BS). This particular part focuses on determining the compressive strength of masonry units, which are essential components in the construction of walls, foundations, and other structures.

To get an accurate reading, the load must be applied evenly. Since bricks often have uneven surfaces, the standard details methods for "capping"—applying a layer of gypsum plaster or mortar to create a flat surface—or grinding the faces flat.
