A fire door is a door with a fire-resistance rating (sometimes referred to as a fire protection rating for closures) used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments of a structure and to enable safe egress from a building or structure or ship. In North American building codes , it, along with fire dampers , is often referred to as a closure , which can be derated compared against the fire separation that contains it, provided that this barrier is not a firewall or an occupancy separation. In Europe national standards for fire doors have been harmonised with the introduction of the new standard EN 16034 , which refers to fire doors as fire-resisting door sets . Starting September 2016, a common CE marking procedure was available abolishing trade barriers within the European Union for these types of products. In the UK, it is Part B of the Building Regulations that sets out the minimum requirements for the fire protection that must be implemented in all dwellings this includes the use of fire doors. All fire doors must be installed with the appropriate fire resistant fittings, such as the frame and door hardware, for it to fully comply with any fire regulations.
29-550: Enhanced CD is a certification mark of the Recording Industry Association of America for various technologies that combine audio and computer data for use in both compact disc and CD-ROM players. Formats that fall under the enhanced CD category include mixed mode CD (Yellow Book CD-ROM /Red Book CD-DA ), CD-i , CD-i Ready , and CD-Extra/CD-Plus ( Blue Book , also called simply Enhanced Music CD or E-CD).

58-496: A British Standard Fire Test BS 476 Part 22 1987, or a BS/EN 1634-1 2000 test. The results are recorded by the test agency and provided in a report which detail such things as constructional details, distortion data and pressure readings. The numerical fire resistance rating that is required to be installed in a particular building is provided in the Building Regulations approved Document B, or British Standards such as
87-401: A Nationally Recognized Testing Laboratory (NRTL, e.g., Underwriters Laboratories). The certification only applies if all parts of the installation are correctly specified and installed. For example, fitting the wrong kind of glazing may severely reduce the door's fire resistance period. As well as ensuring the door is hung properly and squarely, it is also very important that where a fire door
116-448: A claim that the manufacturer has verified compliance with those standards or regulations. The specific specification , test methods , and frequency of testing are published by the standards organization. Certification listing does not necessarily guarantee fitness-for-use. Validation testing, proper usage, and field testing are often needed. Certification marks can be owned by independent companies absolutely unrelated in ownership to
145-445: A common feature of these types of marks is that they may be used by more than one person, as long as the users comply with the regulations of use or standards established by the holder. Those regulations or standards may require that the mark be used only in connection with goods that have a particular geographical origin or specific characteristics. In some jurisdictions, the main difference between collective marks and certification marks
174-584: A range of different materials such as timber or steel. Despite not being fire resistant, timber is used as it has a very predictable char rate, depending on the density and the moisture content timber generally has a char rate of 0.5mm per minute for hardwood and 0.7mm per minute for softwood. Fire doors are sometimes rendered unable to provide their listed fire resistance by ignorance of the intended use and associated restrictions and requirements, or by improper use. For example, fire doors are sometimes blocked open, or carpets are run through them, which would allow
203-438: A test fire. All of the components of the fire door assembly must bear a listing agencies label (with the exception of ball-bearing hinges which meet the basic build requirements of ANSI 156.2 and NFPA 80) to ensure the components have been tested to meet the fire rating requirements. Door hardware includes: Edges of a fire door usually need to have fire rated seals which can be composed of: When intumescent seals are used in

Rated fire doors are tested to withstand an ASTM E119 standard time-temperature curve for a specified period. There are 20, 30, 45, 60, and 90-minute-rated fire doors that are certified by an approved laboratory designated as
290-661: Is installed, any gaps left in the opening between the wall and the door frame must be properly filled with fire resisting material. Fire doors are normally installed by a carpenter . In the UK the British Standard for timber fire door installation is BS 8214: 2016. In the United States, the NFPA requires annual inspections of fire-resistance rated door and frame assemblies. Local Authorities Having Jurisdiction must adopt
319-407: Is that the former may only be used by members of an association, while certification marks may be used by anyone who complies with the standards defined by the holder of the mark. The holder, which may be a private or a public entity, acts as a certifier verifying that the mark is used according to established standards. Generally, the holder of a certification mark does not itself have the right to use

#1732776134357348-570: Is the European Union recognition of Australia and New Zealand marks based on an International treaty . Cases involving certification marks include: Fire door In the UK the British Woodworking Federation outline the difference between a 'Fire Doorset' and a 'Fire Door Assembly'. Fire doors may be made of a combination of materials, such as: Both the door leaf (the swinging panel of
377-483: Is to protect consumers against misleading practices. [REDACTED] New Zealand Many jurisdictions have been required to amend their trade mark legislation to accommodate protection of certification marks under the TRIPs treaty. Some jurisdictions recognise certification marks from other jurisdictions. This means good manufactured in one country may need not go through certification in another. One example
406-485: The Authority Having Jurisdiction (AHJ), such as a municipal building inspector or fire prevention officer. Trademark laws in countries, such as the United States, Australia, and others that provide for the filing of applications to register certificate marks also usually require the submission of regulations, which define a number of issues, including: The main purpose of the regulations
435-518: The BS 5588 series (e.g., 30 minutes FD30, or FD30(S) if cold smoke resistance is also required). Classifications in use which reflect the number of minutes of fire resistance offered are FD30, FD60, FD90 and FD120. Similar technical guidance documents and building regulations are in effect in other countries. Fire doors are not necessarily noncombustible. It is acceptable for portions of the door to be destroyed by combustion during exposure to fire as long as
464-416: The companies, offering goods or rendering services under the particular certification mark. The USPTO states that a certification mark is "a type of trademark ". However, it "is a special creature, created for a purpose uniquely different from that of a trademark or service mark", since: However, what is meant by a collective trade marks or certification mark differs from country to country. However,
493-434: The door assembly meets the fire test criteria of limiting temperature on the non-fire side of the assembly. This is in accordance with the overall performance goal of a fire-rated door to slow fire propagation from one fire rated compartment to another for only a limited amount of time, during which automatic or manual fire fighting may be employed to limit fire spread, or occupants can exit the building. Fire doors are made from
522-558: The door design, use of the correct seal is crucial in the fire rating performance the door assembly. Seals may vary in chemical composition, expansion rate, expansion volume, and/or charring characteristics. Some fire doors are equipped with integral windows which also have a rating , or have been incorporated at the time of the door test and be subject to the overall door's product certification. Fire-resistive windows must remain intact under fire conditions and hose stream impact resistance, and can include: Wired glass typically withstands
551-404: The door) and the door frame are required to meet the guidelines of the testing agency which provides the product listing. The door frame includes the fire or smoke seals, door hardware, and the structure that holds the fire door assembly in place. Together, these components form an assembly, typically called a "doorset" which holds a numerical rating, quantified in minutes or hours of resistance to
580-406: The event of a fire. Whichever method is used, the door's movement should never be impaired by a doorstop or other obstacle. The intumescent and smoke-seal bounding of fire doors should be routinely checked, as should the action of the door closer and latch. Some fire doors are held open by an electromagnet , which is typically wired to a fire alarm system . If the power fails or the fire alarm
609-413: The fire to travel past the fire barrier in which the door is placed. The door's certification markings are displayed both on the door leaves and the fire door frames, and should not be removed or painted over during the life of the building. Sometimes fire doors have apparently very large gaps at the foot of them, an inch or two even, allowing air movement, such as in dormitory facilities. This can lead

In the United States, wire glass must pass the requirements of 16 CFR 1201 and be "labeled" to be used in a door. Laminate and ceramic glasses are now more likely to be used, as they more readily meet the requirements of 16 CFR 2101. All components are required to adhere to product certification requirements that are acceptable to
667-662: The inspection of fire dampers , the fire door inspections are often omitted and many facilities are out of compliance. The final say on the acceptance of any inspection requires the approval of the AHJ (Authority Having Jurisdiction). NFPA 80 includes guidelines concerning field modifications of listed hardware, including frames, builder's hardware, doors, thresholds etc. The growing field of access control and electronic entry systems has resulted in some fire doors being field modified without proper listing agency approval. Field modifications of fire listed assemblies must either be inspected by
696-645: The local Authority Having Jurisdiction (AHJ) by meeting the requirements of the local building code and fire code. The regulatory requirement change from country to country. For example, in Australia, the National Construction Code dictates that all fire doors must be tested to certain specifications in order to meet resistance approvals and certification. In the United Kingdom a fire resisting doorset should be subjected to either
725-505: The mark. For various reasons, usually relating to technical issues, certification marks are difficult to register, especially in relation to services. One practical workaround for trademark owners is to register the mark as an ordinary trademark in relation to quality control and similar services. Certification is often mistakenly referred to as an approval , which is not true. Organizations such as Underwriters Laboratories , TÃœV Rheinland , NTA Inc , and CSA International will test
754-622: The new edition for this requirement to take effect. Most jurisdictions in the US will be adopting the IBC (International Building Code) model code, which references the NFPA 80 2007 edition requirement, as their local codes. NFPA 80 5.2.4.requires the following items shall be verified, at minimum: According to building and fire codes, annual fire door inspections is the responsibility of the building owner. However, as with other mandatory fire inspections, such as
783-573: The occupants of a building to question their status as 'real' fire doors. NFPA 80 allows a maximum door undercut of 3/4 inch, however fire doors are tested with smaller clearances in accordance with NFPA 252. Corridors have a fire rating of one hour or less, and the fire doors in them are required by code to have a fire rating of 1/2 or 1/3 hour, the intent of which is mainly to restrict smoke travel. Most fire doors are designed to be kept closed at all times. Some doors are designed to stay open under normal circumstances, and close automatically in
812-414: The product is held are stipulated by the owner of the certification mark. There are essentially three general types of certification marks: The term "certification mark" is very recent, so while discussing historical certification marks, terms "guild sign", "quality mark", " hallmark ", and "trade mark" are used by researchers. A certification mark indicates a property standard or regulation and
841-432: The products according to standard procedures and "list" them as compliant to that standard. They do not approve anything except the use of the mark to show that a product has been certified for compliance with such specific standard. Thus, for instance, a product certification mark for a fire door or for a spray fireproofing product does not signify its universal acceptance for use within a building . Approvals are up to
