The is the paramount European and British Standard designed specifically for this purpose. This comprehensive guide details the "Methods of test for masonry units - Part 1: Determination of compressive strength," helping manufacturers, engineers, and testing laboratories ensure quality and compliance.
Specimens may need to be conditioned by drying or by being brought to a specific moisture content to ensure consistent results.
is the definitive European and British standard used to determine the compressive strength of masonry units, including clay bricks, concrete blocks, and natural stone. This standardized test method plays a critical role in structural engineering and quality control, ensuring that building elements can safely withstand intended loads. Architectural firms, structural engineers, and testing laboratories routinely utilize the official standard to achieve regulatory compliance and structural validation.
This article serves as a comprehensive guide to the standard, covering its purpose, scope, and where to legitimately access the PDF. bs en 7721 pdf

| | What It Specifies | | --- | --- | | Scope | Defines which drainage channels and slot top surfaces are covered (e.g., for pedestrian and vehicular areas). | | Normative References | Lists other standards (e.g., EN 124, ISO 9001) that must be used alongside BS EN 7721. | | Load Classes | Class 15 (15 kN) to Class 90 (90 kN) – matching typical EN 124 categories. | | Design Requirements | Minimum slot gap width, maximum slot length, and requirements for heel-proof designs. | | Testing Methods | How to perform a load test (using a steel plate and hydraulic press) and corrosion test (240-hour salt spray minimum). | | Marking | All products must be permanently marked with load class, manufacturer logo, and standard number. | | Declaration of Performance (DoP) | Mandatory under CPR – the PDF includes templates for manufacturers. |
BS EN 772-1 standard, titled "Methods of test for masonry units - Part 1: Determination of compressive strength," specifies the European method for measuring the load-carrying capacity of masonry units, such as bricks and concrete blocks. This test is critical for architects, civil engineers, and builders to ensure that structural materials meet the necessary safety and performance requirements for construction.
