BS EN 772-1 is the "Gold Standard" for masonry strength testing. It is a mandatory purchase for any construction professional involved in quality control or structural design involving masonry. While the technical language can be dry, its precision is what ensures the safety and reliability of brick and block structures.
To access the official document, professionals typically purchase the from the BSI Knowledge Store or authorized distributors like Intertek Inform . BS EN 772-1:2011+A1:2015 - BSI Knowledge
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. bs en 7721 pdf
is the harmonized European standard that defines the official test method for determining the compressive strength of masonry units, including clay bricks, concrete blocks, and natural stone. The latest active version is BS EN 772-1:2011+A1:2015 , which incorporates vital amendments to surface preparation and conditioning regimes. Engineers, manufacturers, and testing laboratories frequently seek the BS EN 772-1 PDF to ensure full regulatory compliance and structural integrity in civil engineering works.
Because the height-to-width ratio affects recorded strength, "shape factors" from Annex A are applied to the raw data. BS EN 772-1 is the "Gold Standard" for
[Sampling & Selection] ➡️ [Surface Preparation / Capping] ➡️ [Conditioning (Air/Oven/Wet)] ➡️ [Compression Loading to Failure] ➡️ [Calculation & Shape Factor Adjustment] 1. Sampling and Specimen Count
The test is crucial because it tells designers how much load a unit can handle before failing. The maximum load sustained is recorded, and the
. It provides detailed procedures for specimen sampling, surface preparation (grinding or capping), and the application of continuous uniform loads until failure. www.thenbs.com Access & Downloads
