By following this standard, manufacturers and engineers can verify that building products are suitable for their intended load-bearing applications. Summary of the Testing Process
The standard provides a clear formula to calculate the compressive strength (
When searching for standard documents, ensure you always consult the most current version, as European Standards (EN) undergo systematic reviews every five years to incorporate updated testing methodologies and equipment advancements.
Both standards are parts of a larger system, , which details methods for testing various physical properties of masonry units. It is often used in tandem with the BS EN 771 series , which sets out the product specifications for masonry units (e.g., their required strength and durability). Other important parts of the BS EN 772 series include: bs en 7721 pdf
: Adherence to these standards is often essential for suppliers and quality teams to maintain competitiveness in the electronics industry. Related Standards
BS EN 772-1:2011+A1:2015 is the current British and European standard that defines the official method for determining the compressive strength of masonry units . This part of the BS EN 772 series
BS EN 772-1:2011+A1:2015 establishes the European and British standard for determining the compressive strength of masonry units, including clay, concrete, and stone. It details procedures for conditioning, loading, and calculating normalized strength ( By following this standard, manufacturers and engineers can
BS EN 772-1 provides a comprehensive lookup table of shape factors (
Searching for "BS EN 7721" often leads to a crossroads, as the term is a common abbreviation for two distinct but related British and European standards. The table below highlights their key differences:
As this is a copyrighted technical standard, the only authorized way to obtain the document is through professional standards providers. It is often used in tandem with the

: Compressive strength is calculated by dividing the maximum failure load by the cross-sectional area of the specimen. www.thenbs.com Where to Access the 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.
The Construction Conundrum
The user query "bs en 7721 pdf" (lacking the hyphen) might also be a typo for . This is another critical part of the series. While Part 1 deals with strength, Part 21 specifies a method for determining the water absorption of clay and calcium silicate masonry units by immersing them in cold water. Water absorption is a key factor affecting the quality of mortar and the creep potential of masonry. The standard guides users through the preparation, drying, and testing of specimens to determine water absorption. This is crucial for manufacturers to demonstrate whether their products are fit for their intended use.
