Overview - EN 15254-6:2014 (Curtain walling, fire resistance)

EN 15254-6:2014 is the CEN European standard that defines how to extend or vary the results from fire resistance tests for non-loadbearing walls - specifically curtain walling. It gives guidance and procedural rules for when and how test evidence (primarily from EN 1364‑3 and EN 1364‑4) can be used to predict performance for untested configurations of curtain wall systems and components. The standard applies to curtain walling designs covered by EN 13830 and classified under EN 13501‑2.

Key topics and technical requirements

• Purpose: Formal methodology for interpolation and extrapolation of fire resistance test results (extended application) for curtain walling and components.
• Test evidence ownership: The applicant must be the owner of test data or have written permission to use it.
• No upgrade of classification: You cannot increase classification time or change classification (e.g., E → EW → EI) through extension.
• Overrun time requirement: Extensions often require a test overrun - e.g., ≤20 min: min 3 min overrun; 30–60 min: min 6 min; ≥90 min: min 10% overrun.
• Minimum test basis: At least one EN 1364‑3 full configuration test is required for curtain walling type B; EN 1364‑4 results can be used to supplement.
• System-level and component rules: Specific rules cover complete constructions, framing systems (mullions/transoms), fixing/edge covers, perimeter seals, vertical gap seals and supporting construction (floors/walls).
• Geometric extensions: Rules for width, span, installation angle, vertically/horizontally faceted arrangements (e.g., horizontal angles 45°–315°) are provided - often conditional on meeting the radiation criterion.
• Translucent/transparent infill panels: Special rules on exposure directions and panel types; Annex A contains radiation calculation methods for rectangular, circular and other panel shapes.
• Inclusion of doors/windows: Possible when additional tests per EN 15269 series are performed using the curtain walling as supporting construction (dimension d ≥ 200 mm recommended ≥ 500 mm).

Practical applications and users

Who uses EN 15254‑6:2014:

• Façade and curtain wall manufacturers seeking to apply test results to product variants
• Fire safety engineers and consultants evaluating façade fire performance
• Test laboratories and certification bodies preparing extended application reports
• Architects, specifiers and building authorities assessing compliance with fire resistance requirements Practical value: reduces the need for repetitive full-scale tests by providing validated rules to extend certified fire resistance to similar configurations, saving time and cost while keeping safety demonstrable.
