The BS EN 772-1 PDF is essential for various stakeholders in the construction industry, including architects, engineers, contractors, and building control authorities. Here are some reasons why:
is the British Standard adoption of the European Norm titled “Methods of testing masonry units – Part 1: Determination of compressive strength.”
Compliance with this standard allows manufacturers to prove their products meet required structural safety standards for construction projects. Key Components of the BS EN 772-1 Test Method
For construction professionals, engineers, and testing laboratories, having access to the official is vital. bs en 7721 pdf
The "+A1:2015" indicates an amendment that was adopted to update or clarify sections of the original 2011 standard. The Testing Procedure in BS EN 772-1
The maximum load reached is recorded to calculate the strength in (Megapascals). 3. Conditioning Methods
: Specimens are treated to a specific moisture state before testing. Common conditioning methods include: The BS EN 772-1 PDF is essential for

The standard covers several crucial steps to ensure the accuracy of the compressive strength test. These steps are detailed in the full document, which can be accessed through professional standards platforms. 1. Specimen Preparation and Conditioning
BS EN 772-1 applies to a wide range of masonry units, including: Clay masonry units (bricks) Aggregate concrete masonry units (blocks) Calcium silicate masonry units Autoclaved aerated concrete (AAC) units Summary of Changes and Compliance The "+A1:2015" indicates an amendment that was adopted
: Surfaces must be flat and parallel. If they are not, they may need to be ground down or capped with a compensating layer like gypsum plaster. Conditioning
| Standard Designation | Title | Core Focus | | :--- | :--- | :--- | | | Methods of test for masonry units - Determination of compressive strength | The most frequently referenced part, specifying the procedure to determine the compressive strength (load-bearing capacity) of a masonry unit. | | BS EN 772-2:1998 | Methods of test for masonry units - Determination of percentage area of voids in masonry units (by paper indentation) | Outlines a method for calculating the percentage of voids within a masonry unit, which affects its weight, thermal properties, and strength. | | BS EN 772-7:1998 | Methods of test for masonry units - Determination of water absorption of clay masonry units by boiling in water | Specifies a test to measure how much water a clay masonry unit absorbs after being boiled, a key indicator of its durability in wet conditions. | | BS EN 772-9:1998 | Methods of test for masonry units - Determination of volume and percentage of voids and net volume of clay and calcium silicate masonry units by sand filling | Provides a test method using sand to accurately determine the volume of voids and the net volume of the unit material itself. | | BS EN 772-11:2011 | Methods of test for masonry units - Determination of water absorption of aggregate concrete, autoclaved aerated concrete, manufactured stone and natural stone masonry units due to capillary action and the initial rate of water absorption of clay masonry units | Describes tests for capillary water absorption (wicking) for various unit types and the initial rate of absorption (suction) for clay units. | | BS EN 772-16:2011 | Methods of test for masonry units - Determination of dimensions | Defines a method for determining the overall dimensions, thickness, and other geometric properties of masonry units. | | BS EN 772-20:2000 | Methods of test for masonry units - Determination of flatness of faces of masonry units | Specifies a test to measure the flatness of the bed faces of a masonry unit, which is crucial for a uniform mortar bed. | | BS EN 772-21:2011 | Methods of test for masonry units - Determination of water absorption of clay and calcium silicate masonry units by cold water absorption | Describes a method for determining water absorption by immersing units in cold water, a different approach than the boiling method in Part 7. | | BS EN 772-22:2018 | Methods of test for masonry units - Determination of freeze/thaw resistance of clay masonry units | Specifies a method to determine a clay unit's resistance to freeze-thaw cycles, categorizing them as F1 or F2 based on their durability. |
