For the technical user, this standard is notable for its handling of . Unlike older British Standards (which often used strict mortar capping), BS EN 772-1 permits methods that align with European practice. The choice of capping material can significantly influence the final strength result; the standard provides correction factors to account for the stiffness of the capping material relative to the masonry unit.
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 foundational testing standard used across Europe and the UK to determine the compressive strength of masonry units. This includes bricks, blocks, and stones used in building construction. It is an essential document for manufacturers, testing laboratories, and structural engineers, as the results derived from this test dictate the structural grade (e.g., an "N" or "S" designation) of the masonry. bs en 7721 pdf
There are several ways to obtain a copy of the BS EN 772-1 PDF:
The raw compressive strength value obtained from a testing machine cannot always be compared directly across different sizes of bricks or blocks. To create a uniform baseline, BS EN 772-1 introduces the . The Shape Factor ( For the technical user, this standard is notable
For construction professionals, engineers, and testing laboratories, having access to the official is vital.
: PDF prices vary by country and vendor. Typically, a single-user PDF ranges from €80 to €150 (or equivalent in USD/GBP), plus local taxes. For example, a previous version of the standard (BS EN 772-1:2000) costs around €91.00 (+VAT) from some retailers. It is an essential document for manufacturers, testing
: Variations in brick manufacturing can compromise load-bearing masonry structures.
: Specifies a uniform distributed load applied continuously until the unit fails (reaches its breaking point). Procedural Steps BS EN 772-1:2011+A1:2015 - BSI Knowledge
Masonry unit compressive strength (ASTM/EN equivalent: EN 772-1) Determine the load-carrying capacity of units Status
The compressive strength is calculated by dividing the maximum load at failure by the gross cross-sectional area of the unit.
