Overview
EN 772-2:1998/A1:2005 - Methods of test for masonry units, Part 2 - establishes a standardized procedure for determining the percentage area of voids in masonry units (by paper indentation). Published as a CEN amendment in 2005, this document updates EN 772-2:1998 and is intended for use across CEN member states. It is part of the EN 771/772 family used for masonry testing and product conformity.
Key topics and requirements
- Scope and purpose: Defines the method to quantify the proportion of voids (openings, holes) in masonry units using a paper-indentation technique. This provides a repeatable measure of unit porosity relevant to classification and quality control.
- Test principle (method concept): The paper indentation method produces an imprint of voided regions on a masonry unit so that the percentage area of voids can be calculated. (The standard prescribes the validated procedure and measurement conventions; see the full standard for step-by-step requirements.)
- Normative references: The amendment aligns references to the EN 771 series (EN 771-1 to EN 771-5), tying the test method into the broader product specification and classification system for masonry units.
- Sampling and reporting: Amendment A1 updates sampling and test-report requirements - sampling is referenced to the relevant part of EN 771, and the test report wording is adjusted accordingly.
- Administrative details: Amendment A1 (approved 29 December 2004; published February 2005) is published in English, French and German and must be implemented by CEN national bodies.
Applications
- Quality control in masonry unit production (bricks, blocks)
- Product classification and conformity assessment against EN 771 specifications
- Laboratory testing for material characterization and specification compliance
- Input for performance assessments where void fraction affects thermal behavior, strength categorization or mortar bonding (used in design and specification decisions)
- Regulatory or certification testing for manufacturers and third‑party test houses
Who uses this standard
- Masonry product manufacturers and quality managers
- Independent testing laboratories and technical services
- Certification bodies and notifying authorities
- Architects, structural and specification engineers referencing EN 771 product classes
- Construction material researchers comparing masonry unit characteristics
Related standards
- EN 771-1 to EN 771-5 (product specifications for masonry units)
- Other EN 772 series parts (methods of test for masonry units)
