![]() ![]() This identification label is usually affixed to the top edge of the door. Once the certification is approved, each similarly constructed door set will be identified by a label identifying the manufacturer, the date of manufacture and the designated fire rating of the door type. This door set will then be tested by an approved fire testing centre and, if it is passed, any door sets constructed to that specification can be considered for certification. The first step for the manufacturer is to construct a fire door set designed to a specification that, in their opinion, will resist a fire for a specified length of time. Manufacturers can certify fire door sets, both for identification purposes and to guarantee their performance in a fire situation. Identifying Fire Doors Certified Fire Doors Expert assistance may be required to identify such door sets. Some of these doors have the appearance of timber, but may be constructed with a mineral core. data storage areas where documents cannot be removed in the event of fire. ![]() Fire door manufacturers also commonly send out fire door frames on their own with certification.įire doors with a rating in excess of FD6O are rarely used on escape routes or to protect people but may be found where the preservation of property is important e.g. These fire door leafs can also be used when replacing fire doors that have been damaged or where additional features such as vision panels are required etc. The specification for the frame is either sent with the door or is available on the website of the relevant fire door certification scheme. While fire doors are tested together with a fire door frame and certified as a fire door set, it is common for fire door manufacturers to sell certified fire doors by themselves for use with frames to be constructed by the installer from timber. Stability failure is deemed to occur when collapse of the specimen takes place. Integrity failure is deemed to occur when cracks or other openings develop through which flames or hot gases can pass or when flaming occurs on the unexposed face. Fire resisting doors – door type for means of escape purposes ![]() It is reasonable to assume that all fire doors and door frames manufactured to the same specification as the two specimen doors and frames will then achieve the same fire resisting properties. As a fire door should be tested from each side to establish its performance with either face exposed to fire conditions, two specimens are required. It also provides an objective method of establishing the loss of integrity of a fire door by the use of a combustible fibrous pad on the unexposed side of the door to see when it ignites. The Standard requires the tests to be carried out with the upper part of the door under a small positive pressure, to simulate the conditions likely to occur in a fire. The test procedure is fully described in the Standard and consists of exposing one face of the door to the heat conditions anticipated in a fire while observing the door for stability and integrity. The door set, as it is also known, is fixed in a wall representing its use in practice. the fire door and door frame with all the requisite hardware (e.g. Tests are made on complete fire door sets: ie. To determine the FD rating of fire doors, the manufacturers have their fire doors assessed by subjecting them to a test procedure as specified in BS 476-22:1987 or BS EN 1634-1:2014. Certification testing of timber fire doors The main categories of fire doors are FD30 and FD60 fire doors which offer 30 and 60 minutes fire protection. Fire doors have two important functions in a fire when closed they form a barrier to stop the spread of fire and when opened they provide a means of escape.Ī well designed timber fire door will delay the spread of fire and smoke without causing too much hindrance to the movement of people and goods.Įvery fire door is therefore required to act as a barrier to the passage of smoke and/or fire to varying degrees depending upon its location in a building and the fire hazards associated with that building. These compartments are usually linked by fire doors to allow the flow of traffic around the building. Buildings are compartmentalised to delay the spread of fire from one area to another. ![]()
