This article serves as a comprehensive guide to the standard, covering its purpose, scope, and where to legitimately access the PDF.
The standard, titled "Methods of test for masonry units - Part 1: Determination of compressive strength," is a harmonized European standard used to measure how much weight a masonry unit—such as a brick or concrete block—can withstand before it fails. The latest active version is BS EN 772-1:2011+A1:2015 , which includes amendments for improved surface preparation and conditioning procedures. Core Purpose and Scope bs en 7721 pdf
It includes requirements for slip resistance and gap widths, ensuring that pedestrian heels, bicycle wheels, or mobility scooters do not become trapped.
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.

This standard is titled "Gas turbines and gas turbine sets — Measurement of emitted airborne noise — Engineering/survey method." It specifies methods for measuring sound pressure levels to calculate the sound power level produced by gas turbines and gas turbine sets. It is important to note that this standard is now and has been replaced by BS ISO 10494. If your work involves acoustic engineering rather than construction materials, this is the standard you would need.
The standard, titled "Methods of test for masonry units. Part 1: Determination of compressive strength," is the essential technical reference for verifying the load-bearing capacity of bricks and blocks in the UK and Europe. The current version as of 2026 is BS EN 772-1:2011+A1:2015 , which incorporates the latest amendments for structural integrity. 1.

Always ensure that you're consulting the most current and relevant version of any standard, as updates can occur.
: The testing faces must be made "plane" (perfectly flat) within a tolerance of 0.1 mm over any 100 mm area. If the faces aren't naturally flat, they must be ground down or "capped" with a specific cement/sand mortar.
The standard dictates the use of a calibrated compression testing machine that can apply a uniformly distributed load. 3. Procedure
