A Comprehensive Guide to Fire Door Ratings and Certifications in the UK
Understanding fire door ratings and certifications can feel a little overwhelming. Thankfully, at GD Fire Door Supplier, we simplify the complex world of fire doors to ensure that safety and compliance are always top of mind. Here’s everything you need to know about fire door ratings and fire door certifications, what they mean, how they’re obtained, and why they are crucial.
The Role of Fire Door Ratings and Certifications
Every fire door in the UK is assigned a rating that indicates how long it can withstand fire before it fails. This rating is known as the fire door rating and is typically given in minutes, ranging from 30 to 120 minutes.
Fire door certification provides evidence that the fire door or doorset has been rigorously tested to confirm its ability to resist fire and smoke, and that it meets manufacturing standards. Certification ensures that the door will provide the protection expected during a fire, helping to contain the blaze and prevent the spread of toxic smoke, which is responsible for more fire-related deaths than the fire itself.
Both fire door ratings and certifications are vital in ensuring optimal fire safety for your building. It is crucial for anyone involved in fire safety, whether they are a landlord, building manager, architect, or building designer, to fully understand these terms and their significance in maintaining a safe environment.
Fire Door Ratings: Decoding the Numbers
In the UK, building regulations require fire doors to be tested and certified according to BS 476-22. During the testing process, a complete fire doorset is mounted onto a wall, and the door is subjected to the heat and pressure conditions that mimic a real fire. Independent testing bodies assess the stability and integrity of the door during this exposure. Upon successful testing, the door receives its official fire rating.
Fire doors tested to BS 476-22 typically come with the following ratings:
- FD30
- FD60
- FD90
- FD120
| Fire Door Rating | Duration (Minutes) | Fire Only | Fire and Smoke |
|---|---|---|---|
| 30 | FD30 or E30 | FD30 or E30 | |
| 60 | FD60 or E60 | FD60 or E60 | |
| 90 | FD90 or E90 | FD90 or E90 | |
| 120 | FD120 or E120 | FD120 or E120 |
The FD stands for fire door, and the number represents how many minutes the door can withstand the fire. For instance, an FD60 fire door has passed the test of withstanding a fire for 60 minutes. These ratings are crucial for selecting the appropriate fire door for specific environments. Higher ratings are used in buildings where fire risk is greater or evacuation might take longer.
The Importance of Smoke Control in Fire Doors
It’s important to understand that toxic smoke inhalation is the leading cause of death in fires. Consequently, fire doors must not only resist fire but also limit the spread of smoke. This is why many fire doors are also smoke-resistant. A fire door rated as FD30s, for example, will hold back fire and limit smoke for 30 minutes.
In the UK, fire doors with the ‘s’ designation are recognized as smoke-controlled doors. These doors are especially crucial in public buildings, commercial spaces, and high-rise residential buildings where the spread of smoke can be as deadly as the fire itself.
Fire Window Ratings: How They Relate to Fire Doors
Similar to fire door ratings, fire windows also undergo testing to determine their fire resistance capabilities. Fire-resistant window ratings indicate how long a fire-resistant window can withstand a fire while maintaining its structural integrity. Fire-resistant windows are a vital component in maintaining fire safety in buildings, as they prevent fire from spreading through windows and glass partitions.
Fire-rated window classification is used to describe the level of protection provided by these windows, with performance standards aligned with those of fire doors. When selecting fireproof windows, the window’s ability to withstand heat and prevent the passage of smoke is a critical factor. Fire-resistant glazing ratings typically classify windows based on their ability to hold up to high temperatures for a specific time, such as 30, 60, or 90 minutes. These windows must pass stringent tests to meet fire window performance standards and ensure they provide the necessary protection.
Fire Door Ratings: EN 1634-1 Testing and Certification
Fire doors can also be tested according to EN 1634-1, the European standard for evaluating fire and smoke-resisting doors. Similar to the BS 476 testing process, EN 1634-1 assigns fire doors a rating based on how long they can withstand the spread of fire. Common ratings include E30, E60, E90, and E120, along with their smoke-protective counterparts E30S, E60S, E90S, and E120S.
Though the two testing standards—BS 476 and EN 1634-1—share many similarities, it is crucial to note that a fire door must be explicitly tested to the EN 1634 standard to be officially designated as such. This distinction ensures that the fire door has undergone rigorous testing for both fire and smoke resistance, meeting the necessary safety criteria for various building types and applications.
The Significance of Fire Door Certifications
When installing fire doors, it is essential to use only components such as door leaves, frames, and hardware that are officially certified by a recognized third-party certification scheme. This certification is key to ensuring that fire doors will perform as expected during an emergency, offering the protection required to withstand fire and prevent its spread.
Third-party certification schemes guarantee that fire door assemblies and doorsets have been tested to the British Standard BS 476-22 or the European Standard EN 1634-1 in a UKAS-accredited facility. These certification bodies include reputable organizations such as Certifire, BM–TRADA, IFC, and Bluesky. These schemes not only perform rigorous testing but also involve ongoing factory production control to verify that all fire doors supplied meet the same high standards as those tested.
Fire Door Labels and Certificates of Approval
Fire doors manufactured under third-party schemes are marked with a permanent label affixed to each door. This label includes crucial details such as the door’s fire rating, certification number, and the manufacturer’s details. This labeling ensures transparency and helps building owners, contractors, and inspectors quickly verify the fire door’s performance characteristics.
In addition to the label, fire doors should also be accompanied by a certificate of approval. This document outlines specific installation requirements and limitations, including the positioning of hinges, locks, glazing, and the types of seals that can be used and their installation locations. By adhering to these requirements, the fire door’s performance is optimized to meet its specified fire rating.
If a fire door does not have an approved label or certificate of approval, you cannot be certain of its authenticity or its ability to perform during a fire emergency. This underscores the importance of sourcing fire doors only from reputable manufacturers and certified suppliers like GD Fire Door Supplier.
Integrating Fire Window Ratings into Building Safety
Just as fire doors play a critical role in preventing the spread of fire, fire-resistant windows are equally important in maintaining the safety of a building. Similar to fire door ratings, fire-resistant window ratings indicate how long a window can resist fire and prevent its spread. The fire-rated window classification assigns these windows specific ratings, such as E30, E60, E90, and E120, in line with their performance standards.
For environments where windows are exposed to significant fire risks, fire-resistant glazing ratings are essential in maintaining the building’s integrity during a fire. These ratings determine how long the window can withstand heat and prevent the passage of smoke. Windows designated with the ‘S’ suffix, such as E30S or E60S, offer the added benefit of smoke protection, preventing harmful gases from infiltrating other areas of the building.
By integrating both fire doors and fire windows, building owners can achieve comprehensive fire protection, ensuring that their properties are safeguarded against both fire and smoke.
Why Do Certifications Matter?
Third-party certification of fire doors and doorsets is essential for verifying that the product, when properly installed and maintained, meets the necessary fire door regulations and is suitable for its intended purpose. These certifications provide proof of appropriate testing and confirm that the fire door’s performance is reliable.
Moreover, third-party certifications offer traceability of the product, ensuring that the fire door has been manufactured under strict Factory Production Control (FPC) standards. This reassures building owners, architects, and contractors that the doors meet the necessary fire resistance and safety requirements.
An often overlooked but crucial benefit of third-party fire door certifications is their role in fulfilling insurance requirements. Many insurance policies specify that fire-rated doors must be installed to ensure coverage in the event of a fire. Without official certification, claims could be invalidated or rejected, potentially resulting in financial and legal issues for building owners and occupants.
