SIST EN 1366-1:2014/kFprA1:2020

Fire resistance tests for service installations - Part 1: Ventilation ducts

This Part of EN 1366 specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including those access panels, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This Standard is used in conjunction with EN1363-1.
Annex A provides general guidance and gives background information.
This European Standard is not applicable to:
a)   ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall(where ducts are located in cavities enclosed by fire-resistant shafts or ceilings);
b)   ducts containing fire dampers at points where they pass through fire separations;
c)   one, two or three sided ducts;
d)   fixing of suspension devices (e.g. anchors) to floors or walls.

Overview

SIST EN 1366-1:2014/kFprA1:2020 is a European Standard developed by the European Committee for Standardization (CEN) that specifies the fire resistance testing methods for ventilation ducts used in building service installations. This standard focuses on assessing the ability of both vertical and horizontal ventilation ducts to withstand fire exposure, crucial for maintaining building safety and preventing fire spread.

The testing includes evaluating ducts exposed to fire from both outside (duct A) and inside (duct B) the duct itself. It is intended to be used alongside EN 1363-1, the general fire resistance test method. This standard excludes ducts where fire resistance depends on the surrounding fire-resistant structures, ducts with fire dampers, one- to three-sided ducts, and the fixing of suspension devices to walls or floors.

Key Topics

• Scope of Fire Resistance Tests
  EN 1366-1 outlines methods to measure fire resistance of ventilation ducts including integral access panels. The evaluation considers:

  • External fire exposure (duct A)
  • Internal fire exposure (duct B)

• Types of Ducts Covered
  Suitable for standard vertical and horizontal ducts without fire dampers or enclosing fire-resistant shafts.

• Modifications and Supplementary Requirements
  The amendment FprA1 adds critical updates, particularly for ducts with combustible internal linings such as kitchen extract ducts:

  • Additional thermocouples installed inside ducts for temperature monitoring
  • Specific insulation performance criteria to minimize ignition risks inside ducts
  • Detailed guidance on suspension devices and flexible supporting walls for horizontal ducts

• Performance Criteria
  The standard measures integrity, insulation, and leakage to ascertain overall fire resistance. For ducts with combustible linings, additional emphasis is placed on controlling internal temperatures to prevent internal fuel ignition.

• Exclusions
  Not applicable to ducts where fire resistance comes from walls or ceilings enclosing the ducts, ducts with fire dampers, and ducts fixed by anchors.

• Annex A Guidance
  Provides background information on test procedures and performance criteria, especially differentiating between standard ventilation ducts and kitchen extract or combustible-lined ducts.

Applications

• Fire Safety in Building Design
  EN 1366-1 is essential for architects, engineers, and safety consultants during the design and specification of HVAC systems to ensure compliance with fire safety regulations.

• Building Services Installation Testing
  Manufacturers and testing laboratories use this standard to certify that ventilation ducts meet minimum fire resistance requirements, supporting safe building evacuation and fire compartmentation.

• Kitchen Ventilation Systems
  Particularly important for kitchen extract duct testing, where internal combustible linings increase fire risk, ensuring these ducts are tested with additional rigor to prevent fire spread.

• Fire Protection Products Development
  Enables developers of ventilation duct materials and fire-resistant coatings or linings to validate performance characteristics under fire exposure conditions.

Related Standards

• EN 1363-1: Fire Resistance Tests - General Requirements
  General framework for conducting fire resistance tests applicable to all test methods including ventilation ducts.

• EN 1366 Series - Fire Resistance Tests for Service Installations
  Covers different service installations such as cable trays, electrical ducts, and fire dampers, complementing Part 1 for ventilation ducts.

• EN 14303 - Thermal Insulation Products for Building Applications
  Related to thermal insulation materials used in ducts that might influence fire resistance performance.

• EN 13501-2: Fire Classification of Construction Products
  Classification standard which may include fire resistance ratings derived from tests conducted under EN 1366-1.
