The Difference Between EN and UL Standards & Why You Should Care
Fire rated doors play a critical role in fire protection systems, helping to prevent the spread of fire and smoke between different areas of a building. These fire resistance doors are strategically installed in areas where fire hazards are most likely to occur, ensuring that the integrity of the structure is maintained. This gives occupants the time needed to evacuate safely or defend in place, minimizing the risk of harm during a fire.EN and UL Standards Fire Rated Door.
Fire doors are essential in maintaining the safety of a building, especially in locations where medium or high fire hazards are present. As a fire rated door supplier, we emphasize the importance of correctly installing fire resistance doors in the right areas. Common locations for fire rated doors include:
- Stairwells
- Openings in walls separating buildings
- Mechanical rooms (e.g., generators, boilers)
- Vertical access panels
- Egress routes in buildings
- Electrical rooms (both high and low current enclosures)
Given that fire rated doors are life-saving products, it is crucial that they are properly fitted and installed by certified professionals to meet local safety standards.
Norms & Standards: The Difference Between EN & UL
The installation and specification of fire resistance doors are governed by well-established standards such as NFPA 80 (National Fire Protection Association, American standard) and EN 1634-1 (European standard). These standards define the criteria for fire rated doors, including testing methods, performance requirements, and approvals.
While both standards aim to ensure the effectiveness of fire rated doors in preventing fire spread, they differ in several key aspects. Understanding the distinctions between EN and UL (Underwriters Laboratories) standards is essential for selecting the right fire resistance door for your building. The table below highlights some of the major differences in the specifications and testing processes of fire rated doors:
| Aspect | EN Standards (Europe) | UL Standards (USA) |
|---|---|---|
| Testing Method | Based on standard testing temperatures and durations | Tests doors at higher temperatures for shorter durations |
| Door Construction | Specifies materials, design, and hardware | Focuses on the performance of materials and assembly |
| Approval Process | Certification by accredited European bodies | UL-approved fire doors tested under controlled conditions |
Why You Should Care About EN and UL Standards
Fire rated doors are integral to fire safety systems and should be treated as part of an overall building safety plan. It is important to remember that no single code is superior to another. Both European and American codes can be equally reliable if properly applied. However, the most important factor is to adhere strictly to one fire safety code throughout the entire building, from start to finish. Mixing codes can lead to inconsistencies and potential gaps in fire protection, which could compromise safety in the event of a fire.
As a fire rated door supplier, we always recommend following a single code to ensure full compliance with fire safety regulations. Fire doors built according to one standard may not be suitable under the other’s requirements, and using different standards in various parts of the same building can create confusion and safety risks.
Fire rated doors are crucial components of a building’s fire protection system, specifically designed to contain the spread of fire and smoke. These doors are installed in areas where there’s a significant fire risk, providing occupants with the time to evacuate or defend themselves. Understanding the differences between international standards—such as NFPA 80 in the United States and EN 1634-1 in Europe—is essential for ensuring that your fire resistance doors perform effectively when needed.
The Role of Sprinkler Systems in UL Standards
The US standards for fire rated doors assume that a sprinkler system is installed. For example, under NFPA 80, a fire hose test is required. This test simulates the presence of a sprinkler system by subjecting the door to cold water while testing its ability to withstand fire heat. This assumption is based on the idea that a sprinkler system will control the fire on the external side of the door, allowing the fire rated door to maintain its integrity from the side of the fire.
However, European standards, such as EN 1634-1, do not rely on sprinkler systems. Instead, they emphasize the installation of smoke management systems, which are particularly important since most fire-related casualties occur due to smoke inhalation. This distinction makes the European requirements more stringent, as fire resistance doors must withstand fire and smoke from both sides of the door, even without a sprinkler system.
The Importance of Smoke Sealant in EN Standards
Europe places a unique emphasis on smoke management, which sets it apart from other regions. In line with this approach, fire rated doors in Europe are equipped with smoke sealants. These sealants expand when exposed to high heat, closing any gaps between the door and its frame to prevent smoke from traveling between compartments. This ensures that the building remains safer in the event of a fire, particularly in terms of smoke containment.

Common Grounds Between EN and UL Standards
Despite the differences in fire door testing and installation requirements, both EN and UL standards share a number of similarities when it comes to fire rated doors. These include:
- Regular Maintenance: Both standards emphasize the need for regular maintenance and periodic checks to ensure the door remains in proper working condition.
- Open or Closed Position: Fire doors are designed to remain either open or closed depending on the building’s fire exit plan.
- Technical Areas: Fire rated doors in technical areas must remain closed to contain the fire. In other areas, such as corridors and hallways, the doors are typically held open.
- Fire Door Holders: If a fire door is held open, a fire door holder must be used to maintain the door in its open position. This holder should be released in case of a fire, allowing the door to close and contain the fire.
- Exit Compliance: In areas such as exits and hallways, fire rated doors must open in the direction of the exit to facilitate evacuation. Panic bars are often used to make this process easier.
- Identification and Signage: Clear signage is required on all fire resistance doors to identify the door and indicate whether it should be open or closed during normal operation.
