Overview

EN 772-19:2000 is a European standard developed by CEN that outlines the methods of test for masonry units, specifically focusing on the determination of moisture expansion of large horizontally perforated clay masonry units. This standard applies to clay units where one dimension is at least 400 mm and with shell thicknesses less than 12 mm. By specifying an accelerated testing method, it provides a reliable approach for assessing how moisture influences dimensional changes in these masonry materials.

Key Topics

• Scope of Testing
  The standard is designed for large clay masonry units with horizontal perforations, commonly used in construction. It is particularly relevant for units with one dimension ≥ 400 mm and a shell thickness under 12 mm.

• Moisture Expansion Measurement
  Moisture expansion refers to the dimensional increase that occurs when masonry units absorb moisture. This standard defines accelerated procedures to quantify this behavior accurately.

• Test Methodology
  The prescribed method accelerates moisture absorption to simulate long-term effects in a shorter time frame, allowing manufacturers and engineers to evaluate the durability and stability of masonry units under moisture exposure.

• Material Focus
  The test targets clay masonry units, a critical component in load-bearing and non-load-bearing construction, ensuring materials meet performance expectations.

Applications

• Quality Assurance in Manufacturing
  Clay brick manufacturers use this method to verify that their products comply with moisture expansion limits, minimizing the risk of structural deformation or failure.

• Design and Construction
  Engineers and architects integrate these test results when selecting masonry units for projects, ensuring stability and longevity in environments with varying moisture conditions.

• Material Certification and Compliance
  Test outcomes help demonstrate conformity with European norms, assisting suppliers in meeting regulatory requirements and improving market acceptance.

• Research and Development
  Enables testing of new clay-based masonry products and innovations, facilitating advancements in material performance relating to moisture resilience.
