Appendix B: Fire doors

1. All fire doors should have the appropriate performance given in Table B1 either: A. by their performance under test to BS 476- 22:1987 Fire tests on building materials and structures - Methods for determination of the fire resistance of non-loadbearing elements of construction, in terms of integrity for a period of minutes, e.g. FD30. A suffix (S) is added for doors where restricted smoke leakage at ambient temperatures is needed; or B. as determined with reference to Commission Decision 2000/367/EC of 3 May 2000 implementing Council Directive 89/106/EEC as regards the classification of the resistance to fire performance of construction products, construction works and parts thereof. All fire doors should be classified in accordance with BS EN 13501-2:2003 Fire classification of construction products and building elements. Classification using data from fire resistance tests, (excluding products for use in ventilation systems). They are tested to the relevant European method from the following:

  • BS EN 1634-1:2008 Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware. Fire resistance tests for doors, shutters and openable windows;
  • BS EN 1634-2:2008 Fire resistance tests and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware. Fire resistance characterisation test for elements of building hardware;
  • BS EN 1634-3:2004 Fire resistance tests and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware.- Smoke control test for door and shutter assemblies.
The performance requirement is in terms of integrity (E) for a period of minutes. An additional classification of Sa is used for all doors where restricted smoke leakage at ambient temperatures is needed. The requirement (in either case) is for test exposure from each side of the door separately Any test evidence used to substantiate the fire resistance rating of a door or shutter should be carefully checked to ensure that it adequately demonstrates compliance that is applicable to the complete installed assembly. Small differences in detail (such as glazing apertures, intumescent strips, door frames and ironmongery etc.) may significantly affect the rating. Note 1: The latest version of any standard may be used provided that it continues to address the relevant requirements of the Regulations. Note 2: Until such time that the relevant harmonised product standards are published, for the purposes of meeting the Building Regulations, products tested in accordance with BS EN 1634-1: 2000 (with or without pre-fire test mechanical conditioning) will be deemed to have satisfied the provisions provided that they achieve the minimum fire resistance in terms of integrity, as detailed in Table B1. 2. Fire doors serving an attached or integral garage should be fitted with a self-closing device. 3. Unless shown to be satisfactory when tested as part of a fire door assembly, the essential components of any hinge on which a fire door is hung should be made entirely from materials having a melting point of at least 800ºC. 4. Tables A1 and A2 set out the minimum periods of fire resistance for the elements of structure to which performance of some doors is linked. Table A4 sets out limitations on the use of uninsulated glazing in fire doors. 5. BS 8214:1990 gives recommendations for the specification, design, construction, installation and maintenance of fire doors constructed with non-metallic door leaves. Guidance on timber fire-resisting doorsets, in relation to the new European test standard, may be found in Timber fire-resisting doorsets: maintaining performance under the new European test standard published by TRADA (Timber Research and Development Association). Guidance for metal doors is given in Code of practice for fire-resisting metal doorsets published by the DSMA (Door and Shutter Manufacturers’ Association) in 1999. 6. Hardware used on fire doors can significantly affect performance in fire. Notwithstanding the guidance in this Approved Document guidance is available in Hardware for fire and escape doors published by the Builders’ Hardware Industry Federation.   Table B1 Provision for fire doors Table B1 Provision for fire doors
