ADB1 2019 Para:UNSPECIFIED Table C1 Provisions for fire doorsets

Effective clear width (door stop to projecting ironmongery)
Effective clear width (door stop to door leaf)

ADB1 2019 Para:C1 Fire doorsets C1

All fire doorsets should have the performance shown in Table C1, based on one of the following.
a. Fire resistance in terms of integrity, for a period of minutes, when tested to BS 476-22, e.g. FD 30.
A suffix (S) is added for doorsets where restricted smoke leakage at ambient temperatures is
b. As determined with reference to Commission Decision 2000/367/EC regarding the
classification of the resistance to fire performance of construction products, construction
works and parts thereof. All fire doorsets should be classified in accordance with BS EN 13501-2,
tested to the relevant European method from the following.
i. BS EN 1634-1.
ii. BS EN 1634-2.
iii. BS EN 1634-3.
c. As determined with reference to European Parliament and Council Directive 95/16/EC (which
applies to lifts that permanently serve buildings and constructions and specified safety
components) on the approximation of laws of Member States relating to lifts (‘Lifts Directive’)
implementing the

ADB1 2019 Para:C10 Fire doorsets C10

Unless shown to be satisfactory when tested as part of a fire doorset assembly, the essential components of any hinge on which a fire door is hung should be made entirely from materials that have a minimum melting point of 800°C.

ADB1 2019 Para:C11 Fire doorsets C11

Except for doorsets listed in paragraph C12, all fire doorsets should be marked with one of the
following fire safety signs, complying with BS 5499-5, as appropriate.
a. To be kept closed when not in use – mark ‘Fire door keep shut’.
b. To be kept locked when not in use – mark ‘Fire door keep locked shut’.
c. Held open by an automatic release mechanism or free swing device – mark ‘Automatic fire door
keep clear’.
All fire doorsets should be marked on both sides, except fire doorsets to cupboards and service
ducts, which should be marked on the outside.

ADB1 2019 Para:C12 Fire doorsets C12

The following fire doorsets are not required to comply with paragraph C11.
a. Doors to and within flats and dwellinghouses.
b. Bedroom doors in ‘residential (other)’ (purpose group 2(b)) premises.
c. Lift entrance/landing doors.

ADB1 2019 Para:C13 Fire doorsets C13

The performance of some doorsets set out in Table C1 is linked to the minimum periods of fire resistance for elements of structure given in Tables B3 and B4. Limitations on the use of uninsulated glazing in fire doorsets are given in Table B5.

ADB1 2019 Para:C14 Fire doorsets C14

Recommendations for the specification, design, construction, installation and maintenance of fire
doorsets constructed with non-metallic door leaves are given in BS 8214.
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 the Timber Research and Development Association (TRADA).
Guidance for metal doors is given in Code of Practice for Fire Resisting Metal Doorsets published by
the Door and Shutter Manufacturers’ Association (DSMA).

ADB1 2019 Para:C15 Fire doorsets C15

Hardware used on fire doors can significantly affect their performance in a fire. Notwithstanding the guidance in this approved document, guidance is available in Hardware for Fire and Escape Doors published by the Door and Hardware Federation (DHF) and Guild of Architectural Ironmongers (GAI).

ADB1 2019 Para:C2 Fire doorsets C2

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

ADB1 2019 Para:C3 Fire doorsets C3

The requirement is for test exposure from each side of the doorset separately. The exception is lift doors, which are tested from the landing side only.

ADB1 2019 Para:C4 Fire doorsets C4

Any test evidence used to verify the fire resistance rating of a doorset or shutter should be
checked to ensure both of the following.
a. It adequately demonstrates compliance.
b. It is applicable to the complete installed assembly. Small differences in detail may significantly
affect the rating.
Until relevant harmonised product standards are published, for the purposes of meeting the
Building Regulations, products tested in accordance with BS EN 1634-1 (with or without pre-fire test
mechanical conditioning) that achieve the minimum performance in Table C1 will be deemed to
satisfy the provisions.

ADB1 2019 Para:C5 Fire doorsets C5

All fire doorsets, including to flat entrances and between a dwellinghouse and an integral garage,
should be fitted with a self-closing device, except for all of the following.
a. Fire doorsets to cupboards.
b. Fire doorsets to service ducts normally locked shut.
c. Fire doorsets within flats and dwellinghouses.

ADB1 2019 Para:C6 Fire doorsets C6

If a self-closing device would be considered to interfere with the normal approved use of the
building, self-closing fire doors may be held open by one of the following.
a. A fusible link, but not if the doorset is in an opening provided as a means of escape unless it
complies with paragraph C7.
b. An automatic release mechanism activated by an automatic fire detection and alarm system.
c. A door closer delay device.

ADB1 2019 Para:C7 Fire doorsets C7

Two fire doorsets may be fitted in the same opening if each door is capable of closing the opening,
so the total fire resistance is the sum of their individual resistances. If the opening is provided as a
means of escape, both fire doorsets should be self-closing.
If one fire doorset is capable of being easily opened by hand and has a minimum of 30 minutes’ fire
resistance, the other fire doorset should comply with both of the following.
a. Be fitted with an automatic self-closing device.
b. Be held open by a fusible link.

ADB1 2019 Para:C8 Fire doorsets C8

Fire doorsets often do not provide any significant insulation. Unless providing both integrity
and insulation in accordance with Appendix B, Table B3, a maximum of 25% of the length of a
compartment wall should consist of door openings.
Where it is practicable to maintain a clear space on both sides of the doorway, the above
percentage may be greater.

ADB1 2019 Para:C9 Fire doorsets C9

Rolling shutters should be capable of manual opening and closing for firefighting purposes (see Section 15). Rolling shutters across a means of escape should only be released by a heat sensor, such as a fusible link or electric heat detector, in the immediate vicinity of the door. Unless a shutter is also intended to partially descend as part of a boundary to a smoke reservoir, shutters across a means of escape should not be closed by smoke detectors or a fire alarm system.
