The official standard BS EN 772-1:2011+A1:2015 specifies the methods for determining the compressive strength of masonry units, such as bricks and concrete blocks
. It provides detailed procedures for specimen sampling, surface preparation (grinding or capping), and the application of continuous uniform loads until failure. www.thenbs.com Access & Downloads

The primary standard for determining the structural capacity of masonry products in the UK and Europe is BS EN 772-1:2011+A1:2015. This document, titled Methods of test for masonry units. Determination of compressive strength, establishes the harmonized criteria used by engineers, manufacturers, and testing laboratories to calculate the load-bearing capacity of bricks and blocks.
Acquiring a digital copy of the standard usually involves searching for the BS EN 772-1 PDF. Official, licensed copies should always be obtained directly through authorized distributors like the BSI Knowledge platform or iTeh Standards to guarantee compliance with the latest amendments. Core Scope and Applications
The BS EN 772-1 standard outlines specific procedures to assess how much crushing force a masonry unit can withstand before failing. It serves as a foundational benchmark for building materials referenced in Eurocode 6 (Design of masonry structures). The test applies to various building elements, including: Clay masonry units (traditional fired bricks)
Aggregate concrete masonry units (dense and lightweight blocks) Autoclaved aerated concrete (AAC) units Calcium silicate masonry units Manufactured and natural stone units Key Procedural Steps in BS EN 772-1 The official standard BS EN 772-1:2011+A1:2015 specifies the
To ensure that testing is uniform across different laboratories, the standard mandates strict execution steps: BS EN 772-1:2011+A1:2015 - BSI Knowledge
If you meant BS EN 772-1, that's a very common standard for compressive strength testing of masonry.

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.” BS EN 771 – Specification for masonry units
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 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 foundational testing standard used across Europe and the UK to determine the compressive strength of masonry units. This includes bricks, blocks, and stones used in building construction. It is an essential document for manufacturers, testing laboratories, and structural engineers, as the results derived from this test dictate the structural grade (e.g., an "N" or "S" designation) of the masonry.
The standard outlines the precise methodology required to ensure consistency and repeatability in results. Key sections include:
The final result is calculated by dividing the maximum load by the area of the bearing surface. The standard guides how to calculate the "normalized strength," which adjusts the result based on the size and format of the unit, allowing for comparison between different types of masonry.
