BS EN 772-1 specifies the procedure to determine the compressive strength of masonry units (bricks, blocks, etc.) by applying a compressive load until failure. The standard ensures consistent, comparable strength results across laboratories and manufacturers. If you're looking for a free or more

For the technical user, this standard is notable for its handling of capping. 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.
Many universities with engineering departments have site licenses for BSI standards. If you are a student or academic researcher, you may be able to view or download the PDF for free through your institution’s library portal.
