Overview

EN 1365-2:2014 - “Fire resistance tests for loadbearing elements - Part 2: Floors and roofs” (CEN) defines a standardized method to determine the fire resistance of loadbearing floor and roof constructions with fire exposure from the underside. The standard covers:

• Floor constructions (without cavities or with unventilated cavities)
• Roof constructions (with or without cavities, ventilated or unventilated)
• Floors and roofs incorporating glazing (insulated or uninsulated)

EN 1365-2:2014 is a European test method used together with EN 1363-1 (General requirements) and references EN 1363‑2 and EN ISO 13943 for terminology.

Key topics and technical requirements

• Scope and specimen types: Definitions for floors, roofs, ceilings, cavities, glazed elements, panes, mullions and transoms - including sloped/pitched roof arrangements and configurations that include glazing.
• Test equipment & furnace conditions: Furnace heating, pressure and atmosphere requirements follow EN 1363‑1; for inclined specimens the furnace pressure reference is established 100 mm below the pressure reference line at the highest possible position.
• Loading conditions: Specimens are subjected to representative loads; loads should produce moments and shear forces equal to or greater than those in service. Uniform application via point-loading systems is specified; distribution plates must not exceed 0.09 m2 each or 16% of total surface area collectively.
• Specimen design & size: Requirements for specimen dimensions, support and restraint conditions, and construction details (including ceilings and pitched roofs).
• Instrumentation & measurements: Use of furnace thermocouples (plate thermometers), unexposed-surface thermocouples, pressure, deflection and radiation measurement. Annex A specifies additional instrumentation and criteria for constructions incorporating glazing, including average and maximum temperature rises, deflection limits and radiation checks.
• Performance criteria & reporting: Criteria for fire resistance (integrity, insulation where applicable, and radiation) and mandatory contents for the test report. Fields of direct application (limits on span, width, inclination and support types) are defined for transferability of test results.

Applications and who uses it

EN 1365-2:2014 is used by:

• Fire test laboratories conducting standardized fire-resistance tests
• Structural and fire safety engineers assessing loadbearing floor/roof performance under fire
• Manufacturers of floors, roofs, glazing systems and composite assemblies for product certification and CE marking
• Building designers and code officials for compliance demonstration and approval processes
  Practical uses include product development testing, regulatory compliance, verification of glazed roof/floor solutions, and establishing fire-resistance ratings used in building design and specification.
