Overview

EN 846-9:2016 is a European Standard developed by CEN that specifies methods for testing the flexural resistance and shear resistance of lintels used in masonry construction. Lintels, which support loads over openings like doors and windows, must be rigorously evaluated to ensure structural integrity and safety. This standard focuses on determining flexural strength, shear resistance, and load-deflection characteristics of single-span lintels, whether single or composite, supporting uniformly distributed loads in masonry walls.

The standard replaces the earlier EN 846-9:2000 version and aligns with relevant materials and testing specifications, including EN 845-2 for ancillary masonry components. By providing consistent test methods, EN 846-9:2016 supports harmonized quality control and performance validation of masonry lintels across European member states.

Key Topics

• Scope and Purpose
  Defines procedures to test single or composite lintels for flexural and shear resistance under simulated service loading conditions.

• Materials and Sampling
  Specifies compliance with EN 845-2 for structural casing units and manufacturer’s specifications for composite lintels. Specifies minimum sample sizes for tests.

• Test Apparatus
  Requires a test rig capable of withstanding applied loads without distortion, accurate loading systems (±2%), and precise deflection monitoring equipment.

• Test Procedures

  • Simple support conditions with minimum bearing lengths and optional bedding mortar.
  • Loading protocols: continuous or incremental loading with monitoring over 15-30 minutes to failure.
  • Use of uniformly distributed loads or equivalent point load arrangements for flexural tests.
  • Shear resistance tested by applying loads near support edges with specified distances and spreader plates.
  • Deflection monitoring at mid-span vertically and horizontally with adjustments for wall leaf conditions.

• Load Arrangements
  Illustrates two-point and four-point loading setups tailored for single, combined, and composite lintels to replicate real stress distributions.

• Evaluation and Reporting
  Test results expressed as mean failure loads with detailed reporting requirements including material specs, loading setups, deflection data, failure modes, and visual documentation.

Applications

EN 846-9:2016 is essential for manufacturers, testing laboratories, and construction engineers involved in:

• Quality Control of masonry lintels to ensure compliance with regulatory and safety standards.
• Product Development by providing standardized test methods to validate new lintel designs and materials.
• Structural Safety Assessment for existing or new masonry openings, supporting design verification.
• Regulatory Compliance with European and national building codes harmonized through CEN standards.

This standard is applicable to lintels supporting uniformly distributed loads in various masonry structures, including residential, commercial, and infrastructural buildings across Europe.

Related Standards

• EN 845-2 – Specification for ancillary components for masonry, including lintels, specifying dimensional and material requirements.
• EN 772-1 – Methods for testing masonry units, relevant for assessing compressive strength of components used in lintels.
• EN 998-2 – Specification for masonry mortar, critical where lintels are bedded on mortar for proper support.
• EN 1015-11 – Test methods for mortar, including flexural and compressive strength of hardened mortar, relevant for bedding conditions.

By following EN 846-9:2016 in conjunction with these harmonized European standards, stakeholders ensure that masonry lintels meet performance criteria essential for durability, safety, and longevity in construction projects.
