Methods of test for masonry units - Part 1: Determination of compressive strength

The load is applied perpendicular to the bed face of the masonry unit.

The standard details several critical steps to ensure accuracy and repeatability across different laboratories: bs en 7721 pdf

: The compressive strength is calculated by dividing the maximum load at failure by the cross-sectional area of the specimen. Why This Standard Matters

The units are subjected to compressive loads in a calibrated testing machine. The standard specifies: How fast the load is applied to the sample. Methods of test for masonry units - Part

The standard outlines a procedure where a prepared test specimen is placed centrally on the lower platen of a compression testing machine. A uniformly distributed load is then applied and increased continuously until the specimen fails. The maximum load sustained is recorded, and the compressive strength is calculated by dividing this failure load by the cross-sectional area of the specimen, with the result expressed in N/mm² (Megapascals, or MPa). The standard provides comprehensive details for every step of this process, including the preparation of specimens, required materials and apparatus, the precise calculation of results, and the format of the final test report. These declared values are essential for structural calculations and for UKCA or CE marking of products.

: Used by manufacturers to demonstrate the reliability and performance of their construction products. Key Technical Requirements The standard specifies: How fast the load is

If you meant , that's a very common standard for compressive strength testing of masonry.

The standard, officially titled "Methods of test for masonry units - Part 1: Determination of compressive strength," is the definitive European and British technical document used to measure how much pressure a building block can withstand before it fails. It is a critical part of the BS EN 772 series and ensures that materials used in walls and partitions meet safety requirements for structural integrity. Core Purpose and Scope
