EN 1366-12:2014/prA1

Fire resistance tests for service installations - Part 12: Non-mechanical fire barrier for ventilation ductwork

This part of EN 1366 specifies a method for determining the fire resistance of non-mechanical fire barriers installed in fire separating elements designed to withstand heat and the passage of smoke and gases at high temperature. This European Standard is used in conjunction with EN 1363 1 and EN 1366 2.
This European Standard is not suitable for testing non-mechanical fire barriers in suspended ceilings without modification.
This European Standard is not suitable for testing fire dampers, see EN 1366 2.
This European Standard is not suitable for testing such products as air transfer grilles, as the pressures and flows involved are different and may cause differing behaviour.

Overview

EN 1366-12:2014/prA1 is a European standard developed by CEN that specifies the fire resistance testing methods for non-mechanical fire barriers used in ventilation ductwork. These barriers are designed to prevent the spread of fire, smoke, and hot gases through ventilation ducts in fire-separating elements within buildings. The standard complements EN 1363-1 and EN 1366-2, providing a unified framework for assessing the safety and integrity of duct-installed fire barriers under fire conditions.

This standard is essential for manufacturers, testing laboratories, and regulatory bodies involved in fire safety and building design. It focuses exclusively on non-mechanical fire barriers and excludes mechanical fire dampers, air transfer grilles, and suspended ceiling installations without modification.

Key Topics

• Scope and Application
  EN 1366-12 covers non-mechanical fire barriers installed within ventilation ductwork, ensuring they maintain functional integrity under fire conditions. It specifically excludes applications such as fire dampers (covered by EN 1366-2) and air transfer grilles, where differing air pressures and flow rates affect performance testing.

• Fire Resistance Testing Methodology
  The standard outlines detailed procedures for testing fire barriers according to controlled pressure differences, temperature exposure, and leakage criteria. It emphasizes maintaining a pressure difference of 300 Pa ± 15 Pa during tests to simulate realistic operating conditions and measure leak rates accurately.

• Performance Criteria and Leakage Limits
  For successful certification, fire barriers must demonstrate minimal leakage-less than or equal to 12 m³/h at a specified pressure differential or an adjusted value depending on the test conditions. The standard provides clear performance criteria based on continuous monitoring during the fire resistance test.

• Amendments and Modifications
  The 2019 amendment prA1 updates the test procedures and performance criteria, such as adjusting measurement timings from 5 minutes to 3 minutes and refining leakage testing subclauses to improve reproducibility and accuracy in fire resistance assessments.

Applications

• Building Fire Safety Engineering
  EN 1366-12 informs the design and installation of passive fire protection systems in ventilation ductwork, contributing to overall fire compartmentation and occupant safety in residential, commercial, and industrial buildings.

• Product Development and Certification
  Manufacturers of fire-resistant ventilation components use this standard to test and certify non-mechanical fire barriers, ensuring compliance with European fire safety regulations and enhancing product marketability across Europe.

• Regulatory Compliance
  Authorities and certification bodies rely on EN 1366-12 to verify that installed fire barriers meet mandatory fire resistance requirements, which are part of essential construction product regulations.

• Fire Risk Assessment and Mitigation
  Engineers audit existing ventilation systems using the principles outlined in the standard to identify potential weaknesses or failures in fire-separating barriers.

Related Standards

• EN 1363-1: Fire Resistance Tests - General Requirements
  Provides general instructions for conducting fire resistance tests that complement EN 1366-12 testing of ventilation fire barriers.

• EN 1366-2: Fire Resistance Tests for Service Installations - Fire Dampers
  Defines testing procedures specifically for mechanical fire dampers, distinguished from non-mechanical barriers in ventilation ducts.

• EN 13501-2: Fire Classification of Construction Products and Building Elements
  Covers classification and performance criteria of fire resistant products, useful in conjunction with product testing under EN 1366-12.

• EN 12101 Series: Smoke and Heat Control Systems
  Offers standards for systems controlling smoke and heat spread, often integrated with fire barrier solutions in ventilation ductwork.

---

By adhering to EN 1366-12:2014/prA1, professionals in fire safety and building services can ensure that ventilation duct non-mechanical fire barriers are robust, reliable, and compliant with European technical regulations, thereby safeguarding property and lives through enhanced fire containment.
