"John, we need to make sure those masonry units meet the compressive strength requirements," his boss had said. "I want you to review the test results and ensure they comply with BS EN 772-1."

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

, which includes the 2015 amendment regarding surface preparation and conditioning.

: Testing machines must feature two steel-bearing platens, one of which must be able to align freely upon contact with the specimen. "John, we need to make sure those masonry

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.

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.
