BS EN 772-1 is a British Standard that outlines the methods for testing the properties of masonry units, such as compressive strength, density, and water absorption. The standard is part of a series of European Norms (EN) that have been adopted by the British Standards Institution (BSI) to harmonize construction standards across the European Union. The full title of the standard is "Masonry units - Part 1: Determination of compressive strength."
