This post summarizes the purpose and technical requirements of BS EN 772-1, the official British and European standard for testing the compressive strength of masonry units. What is BS EN 772-1?
Loading: The unit is centered on the platens of a compression testing machine. A uniform load is applied and increased continuously until the unit fails or "crushes".
Searching for the BS EN 7721 PDF usually indicates a need to verify: bs en 7721 pdf
Durability: The standard mandates corrosion resistance tests (e.g., salt spray testing for metallic components), ensuring that products last decades in harsh environments.
Conditioning by Immersion: Units are saturated in water, which often results in a lower measured strength compared to dry states. 4. Results and Normalisation This post summarizes the purpose and technical requirements
Q: Is BS EN 772-1 PDF mandatory?
BS EN 772-1:2011+A1:2015 establishes the European and British standard for determining the compressive strength of masonry units, including clay, concrete, and stone. It details procedures for conditioning, loading, and calculating normalized strength ( A uniform load is applied and increased continuously
Quality Verification: Used by manufacturers to demonstrate the reliability and performance of their construction products. Key Technical Requirements
The speed at which the hydraulic press applies force is critical. Applying force too fast can result in a lower strength value due to shock, while applying it too slowly is inefficient. The BS EN 7721 document specifies the exact rate of loading in Newtons per second (N/s).
