Overview
EN 772-20:2000 (CEN) is the European test method for determining the flatness of faces of masonry units made from aggregate concrete, manufactured stone and natural stone. The standard defines a reproducible procedure to measure and report how flat the visible faces of masonry units are, supporting product verification and quality control in masonry manufacturing and construction.
Key Topics
- Scope and applicability: Applies to aggregate concrete, manufactured (reconstituted) stone and natural stone masonry units intended for use in buildings and structures.
- Definition of flatness: Establishes the parameter(s) and terminology used to describe face flatness for masonry units.
- Test method: Specifies a standardized approach for selecting specimens and carrying out measurements to assess flatness. (Note: this summary does not reproduce detailed procedural steps or numerical tolerances from the standard.)
- Measurement and instrumentation: Covers the types of measurement techniques and instruments appropriate for flatness assessment (e.g., straightedges, feeler gauges, or measuring devices), and how results should be recorded.
- Reporting and documentation: Outlines the essential information to include in test reports to ensure traceability and comparability of flatness results.
- Quality criteria: Provides the basis for deciding conformity of masonry units with specified flatness requirements as agreed between manufacturer, purchaser or regulator.
Applications
- Manufacturers: Routine quality control of masonry products (aggregate concrete blocks, manufactured stone units, or natural stone) to ensure consistent face flatness and visual quality.
- Test laboratories: Performing standardized flatness testing for certification, product development, dispute resolution or compliance verification.
- Specifiers, architects and contractors: Using flatness data to assess suitability of masonry units for finished surfaces, cladding, or precision masonry work where surface evenness affects installation or appearance.
- Regulatory and procurement bodies: Verifying that supplied masonry units meet contractual or regulatory flatness requirements.
Related Standards
- EN 772-20 is part of the EN 772 series of test methods for masonry units and is typically used alongside product standards for masonry units (for example, EN product specifications) and other test methods that measure mechanical, physical and durability properties.
