If you need help interpreting specific sections of the standard, let me know: What you are testing (clay, concrete, AAC)? What conditioning method you plan to use? Do you need assistance calculating the shape factor ? Share public link
The load is applied steadily until failure (crushing) occurs. Measurement: The maximum load at failure is recorded. 4. Calculation of Compressive Strength
It is necessary to demonstrate that materials meet legal and building regulation requirements. bs en 7721 pdf
When engineers design a building, they calculate the loads the walls must support. These calculations are based on the "declared values" of the materials. If the compressive strength of a brick is not tested correctly, the safety margins of the entire building could be compromised.
Other standards databases, such as IHS Markit or Techstreet, often carry this document. If you need help interpreting specific sections of
: A testing machine applies a uniform, continuous load until the specimen fails. The standard mandates specific platen hardness (at least 600 HV) and stiffness to prevent deflection that could skew results. BS EN 772-1:2011+A1:2015 - BSI Knowledge

The final result is calculated by dividing the maximum load by the area of the bearing surface. The standard guides how to calculate the "normalized strength," which adjusts the result based on the size and format of the unit, allowing for comparison between different types of masonry.
