Understanding Fire Door Standards

Fire door standards are put in place to ensure that every component of a fire door performs effectively during a fire. These standards are being updated to align with European testing and classification systems.

What’s Changing in Fire Door Testing?

The fire door and hardware industry is entering a big transition. From September 2029, evidence based on BS 476 fire door testing will no longer be accepted for compliance. Historically, manufacturers relied on this testing method but must now demonstrate performance under the EN 13501 fire classification system, with BS EN 1634-1 as the key test standard for fire doors.

Under BS 476, product variations such as door size and glazing could often be covered through assessment procedures. Under the new testing requirements (EN 1634-1), these variations are managed through strict ‘direct application’ rules or via Extended Application Procedures (EXAPs).

Why are the Standards Changing?

These standards are changing to align with the more internationally recognised EN testing system. Therefore, the UK Government is working to modernise fire safety testing, providing greater assurance that fire doors will perform as intended. This change enhances safety and accuracy, reflecting the industry’s commitment to improving fire door performance.

How will this affect you?

Door manufacturers will be directly affected by these changes and will need to review and align their processes to ensure compliance. Test evidence must be reviewed to identify products supported only by BS 476 data, and existing fire door test reports need to be checked against EN standards. Finally, a testing plan must be developed to achieve EN 1634-1 evidence for their full product range. With the five-year transition already underway, and many manufacturers already testing to EN 1634-1 as standard, now is the ideal time to begin aligning processes.

FAQs

What are the requirements for a FD30 fire door?

FD30 fire doors are designed to resist fire for at least 30 minutes. They must be certified as FD30 and be used with compatible fire-rated frames, hinges, and hardware. These doors are usually 44mm thick, with intumescent seals fitted around the edges and, in most cases, a self-closing device is also required.

Do I need 30 minute or 60 minute fire doors?

Your location will influence what fire door you need. Most residential properties require FD30 fire doors, which are designed to resist fire for at least 30 minutes. FD60 fire doors are rated for 60 minutes, and are more commonly needed in larger buildings, commercial spaces, or high-risk areas. If you’re unsure, consult a fire safety professional to confirm the necessary rating for your property.

Do fire doors need drop-down seals? Drop-down seals are required if the door needs to provide smoke control. These work to seal gaps at the bottom of the door when it closes, preventing smoke from spreading between rooms. Check the fire door’s certification and installation instructions to confirm whether your door needs a drop-down seal.

Can I fit a fire door myself? Yes, you can fit a fire door yourself in a private home, but you must follow the manufacturer’s installation instructions carefully. You will also need the correct frame, seals, hinges, self-closer, and hardware. Using a qualified fire door installer is recommended for the best results and full compliance. From September 2029, new or replacement fire doors must be classified using EN 1634-1 / EN 13501 rather than BS 476.

How do I know if my fire door is compliant?

Certification labels will verify that fire doors are compliant. Ensure that from September 2029 your fire door holds EN 1634-1 / EN 13501 classification rather than BS 476 certification. Check that the gaps between the door and frame are typically 2-4mm, and that all seals are intact. Also, ensure the door has a functioning self-closing mechanism and the correct fire-rated ironmongery.
