Overview

EN 12101-3:2015 is the CEN European standard that defines product characteristics, test methods and compliance criteria for powered smoke and heat control ventilators (fans) used in construction works. It applies to both general fans for smoke and heat control and impulse/jet fans. The standard sets out how to assess performance, reliability and fire resistance so ventilators can be specified and certified for use in smoke and heat control systems.

Key topics and technical requirements

EN 12101-3:2015 covers technical topics and test/assessment procedures, including:

• Scope and definitions - specifies the types of powered ventilators and intended applications within construction works.
• Performance requirements
  • Response delay (response time) - ability to open and operate within specified time under conditions such as wind or snow load.
  • Effectiveness of smoke/hot gas extraction - gas flow and pressure maintenance during extraction tests.
• Operational reliability and durability - application categories, motor rating, long-term durability and criteria for family-based testing.
• Resistance to fire - test methods for fan functionality and integrity when exposed to fire conditions (normative fire-resistance testing).
• Environmental opening ability - opening under wind and snow loads within given time frames.
• Testing and assessment - type testing, sampling, test reports, and compliance criteria.
• Assessment and Verification of Constancy of Performance (AVCP) - factory production control (FPC), initial inspection and ongoing surveillance requirements for manufacturers.
• Annexes - criteria for selecting representative fan and motor sizes for testing, detailed motor tests (including methods to evaluate impact of motor changes), and a normative test for fan fire resistance.
• Marking, labelling and packaging - required product information for traceability and specification.

Practical applications

EN 12101-3:2015 is used to ensure that powered smoke and heat control fans meet consistent safety and performance expectations in buildings and other construction works. Typical applications include specification, testing and acceptance of fans used in:

• Smoke and heat exhaust ventilation systems (mechanical smoke control)
• Impulse/jet fan installations to control smoke movement
• Integration into building fire safety designs and performance-based smoke control strategies

Who uses this standard

• Manufacturers of powered smoke and heat control fans (design, testing, production control)
• Fire safety engineers and consultants specifying smoke control components
• Building designers and architects requiring verified ventilator performance
• Testing laboratories and certification bodies performing type testing and AVCP assessments
• Authorities having jurisdiction reviewing compliance with fire safety regulations

Introduction
Smoke and heat control ventilation systems create a smoke free layer above the floor by removing smoke and thus
improve the conditions for the safe escape and/or rescue of people and animals and the protection of property and
permit the fire to be fought while still in its early stages. They also exhaust hot gases released by a fire in the
developing stage.
In specific cases some fans are used to convey smoke (e.g. in tunnels or car parks). These fans, called jet fans or
impulse fans are also within the scope of this standard.
The use of smoke and heat control ventilation systems to create smoke free areas beneath a buoyant smoke layer
has become widespread. Their value in assisting in the evacuation of people from construction works, reducing fire
damage and financial loss by preventing smoke logging, facilitating fire fighting, reducing roof temperatures and
retarding the lateral spread of fire is firmly established. For these benefits to be obtained it is essential that smoke
and heat control ventilators operate fully and reliably whenever called upon to do so during their installed life. A
heat and smoke control ventilation system is a scheme of safety equipment intended to perform a positive role in a
fire emergency.
Components for smoke and heat control systems should be installed as part of a properly designed smoke and
heat control system.
Smoke and heat control ventilation systems help to:
— keep the escape and access routes free from smoke;
— facilitate fire fighting operations by creating a smoke free layer;
— delay and/or prevent flashover and thus full development of the fire;
— protect equipment and furnishings;
— reduce thermal effects on structural components during a fire;
— reduce damage caused by thermal decomposition products and hot gases.
Depending on the design of the system and the ventilator, powered or natural smoke and heat ventilators can be
used in a smoke and heat control system. Powered smoke and heat control ventilators (fans) can be installed in the
roof or upper part of walls of building or in a ducted system with the ventilator inside or outside the smoke reservoir
or in a plant room.
Powered smoke and heat control ventilation systems should operate based on powered ventilators (fans). The
performance of the powered smoke and heat control system depends on:
— the temperature of the smoke;
— size, number and location of the exhaust openings;
— the wind influence;
— size, geometry and location of the inlet air openings;
— the time of actuation;
— the location and conditions of the system (for example arrangements and dimensions of the building).
Smoke and heat control ventilation systems are used in buildings or construction works where the particular (large)
dimensions, shape or configuration make smoke control necessary.
Typical examples are:
— single and multi-storey shopping malls;
— single and multi-storey industrial buildings and warehouses;
— atria and complex buildings;
— enclosed car parks;
— stairways;
— tunnels;
— theatres.
