The process is designed to find the maximum load a unit can withstand before failure.

Masonry unit compressive strength (ASTM/EN equivalent: EN 772-1) Determine the load-carrying capacity of units Status bs en 7721 pdf

Material strength can vary significantly based on moisture. The standard specifies several conditioning paths prior to testing: Samples are stored at and 60% relative humidity for a minimum of 14 days. Oven-dry: Specimens are dried to a constant mass at and cooled before testing. The process is designed to find the maximum

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.

The speed at which the load increases is regulated to ensure consistent results. Where to Find the BS EN 772-1 PDF

The standard was first published in its current form in 2011, with an amendment (A1) added in 2015. The most recent and current version is .

A: European Standards, including BS EN 772-1, are reviewed and updated regularly to reflect changes in technology, market requirements, and regulatory needs. The frequency of updates depends on the standard's relevance and the need for revision.
