Smoke Tested
Smoke tested access panels and riser doors certified to BS EN 1634-3:2004. Ambient and medium temperature classifications for complete smoke control at service openings.
Lead Time: 3-5 working days | Bespoke: 4 working days
A smoke tested access panel is a hinged or removable panel that has been independently tested and classified for resistance to smoke leakage at service openings in walls, ceilings and floors. Smoke is the primary cause of death in building fires, and uncontrolled smoke migration through service risers, ceiling voids and corridor walls can compromise escape routes long before flames reach those areas. Smoke tested access panels and riser doors prevent smoke from passing through the building at these critical points.
Smoke leakage testing is carried out to BS EN 1634-3:2004 at an independent UKAS accredited laboratory. Products are classified under two conditions: Sa (ambient temperature, approximately 25°C) which measures cold smoke leakage before a fire reaches the panel, and S200 (medium temperature, 200°C) which measures smoke leakage under elevated temperature conditions as a fire develops nearby. Both classifications are important because smoke begins to spread through a building well before the fire itself reaches the access panel or riser door location.

UNDERSTANDING smoke control
BS EN 1634-3 defines two smoke leakage classifications. Understanding the difference helps you specify the correct level of smoke control for your project.
Cold smoke leakage at approximately 25°CThe Sa classification measures smoke leakage at ambient temperature, approximately 25°C. This represents the early stage of a fire event when smoke is already migrating through the building, but the fire has not yet raised temperatures at the access panel location. Cold smoke is particularly dangerous because it spreads rapidly through corridors, stairwells and service risers, reducing visibility and contaminating escape routes before occupants are aware of the fire. Sa testing confirms that the panel’s seals and construction prevent smoke passing through the opening under these conditions.Tested at 25°CEarly stage fire protection
Warm smoke leakage at 200°CThe S200 classification measures smoke leakage at 200°C, representing conditions where a fire has developed and elevated temperatures are present in the vicinity of the panel or door. At this stage, thermal expansion, gasket degradation and pressure differentials are all working to force smoke through any gaps in the building fabric. S200 testing confirms that the product continues to resist smoke passage even as temperatures rise significantly. Products achieving both Sa and S200 provide protection across the full development of a fire event.Tested at 25°CDeveloped fire protectionOur smoke tested range
Smoke tested options are available in metal faced and plasterboard faced configurations across our access panel and riser door ranges.
Applications
Smoke control is a critical element of fire safety strategy. Access panels and riser doors in the following locations should be specified with smoke testing certification.
Service risers, corridors, suspended ceilings and plant rooms
Bathrooms, utility spaces, loft access and apartment risers
Wards, corridors, clean rooms and service voids
Classrooms, halls, corridors and multi-storey buildings
Transport hubs, data centres, utilities and public buildings
