Fire door hardware requirements in India sit in one clause. Clause 7.2.9 of IS 3614:2021 says every item of hardware on a fire door shall be fire rated and certified, allows two narrow exemptions, and names four fittings that are not permitted on a fire door at all. A certified leaf on uncertified ironmongery is not a certified doorset.
Page one answers for the wrong country
The published guidance on this subject is almost entirely British or American. UK pages work from BS EN 1935 for hinges and BS EN 1154 for closers and arrive at a familiar rule of thumb: three fire-certified hinges, CE or UKCA marking on every component. US pages run on NFPA 80. Neither system governs a building approval in Nashik, Pune or Mumbai.
Here the governing document is IS 3614:2021, Fire Doors and Doorsets - Specification, as amended by Amendment No. 1 of 2023, read alongside the fire and life safety provisions now in Part F of SP 7:2026. We covered that change and what it did to rating selection in the guide to where FD60 and FD120 belong. This article covers what goes on the door.
What clause 7.2.9 actually says
The clause opens with the rule that decides most disputes: "All hardware used on fire doors shall be fire rated, and certified except for hinges, if it is of minimum size 100 mm x 75 mm x 3 mm and in stainless steel of grade SS 304 and above."
It then extends the requirement by name: "All other mechanical and functional hardware like, locks, panic devices, lever handles, door closers, shall be type tested and certified for use on fire doors for specified rating."
So there are exactly two exemptions, and both turn on material rather than on the item being unimportant. Hinges are exempt only at 100 mm x 75 mm x 3 mm or larger in SS 304 or above. Pull handles are treated the same way. Every other functional item on the door needs a certificate of its own.
Item by item
1. Hinges: the standard does not give you a number
This is the biggest divergence from the page-one guidance. IS 3614:2021 does not prescribe how many hinges a leaf must carry. It prescribes a size and grade below which a hinge must be separately certified, and leaves the count and pattern to the tested assembly.
That is stricter in practice, not looser. Hinge count, fixing and position are part of what was tested, so the answer for a given doorset is whatever its test evidence records. Annex A lists IS 1341 for steel butt hinges and IS 12817 for stainless steel butt hinges as the product specifications. When a supplier answers "three, same as the UK", ask to see the hinge specification on the test report instead.
2. Door closers
Clause 7.2.9 is unambiguous that self-closing is not optional: "All fire doors once installed shall be self-closing." The closer must be type tested and certified for the rating, and the standard is specific about where the proof lives - it requires a "Visible label of certification on the door closer body (does not include covers)".
That parenthesis is worth reading twice. A closer marked only on its cover plate fails verification the moment an inspector removes two screws. Annex A separately references IS 3564, IS 14912 and IS 6315 for closers and floor springs, but those are product standards for the mechanism, not a substitute for fire certification on the doorset.
3. Locks, latches and flush bolts
A dead lock without a latch, cylinder operated, is permitted subject to the door having been tested in the unlatched condition. That condition is the point: if the test evidence shows a latched specimen, an unlatched dead lock sits outside it.
For double leaf doors the standard is prescriptive: "All double leaf doors shall have concealed lever action flush bolts on top and bottom of the inactive leaf (except panic device door)." Above 2 100 mm door height the flush bolt is required with an extended rod, and clause 7.2.5 adds that all double leaf assemblies shall be provided with and tested with astragals. Surface-mounted barrel bolts on the inactive leaf, still common on site, meet none of this.
4. Panic and emergency exit hardware
IS 3614:2021 treats emergency exit devices the way it treats closers: a visible certification label on the device. It also settles a recurring drawing-office argument by allowing panic device projections within the clear width of the door.
The requirement to fit them comes from the building side. Part F of SP 7:2026 defines fire exit hardware at clause 2.38 as "A door-latching assembly incorporating an actuating member or panic bar that releases the latch bolt upon the application of a force in the direction of egress travel, provided on exits", and clause 2.16 states that fire exits should be provided with a panic bar as applicable.
5. Electromagnetic and electrified locks
These are permitted with one hard condition. The standard allows electromagnetic and electrified security locks in combination with other hardware such as latches and panic devices, provided they are of the fail-safe type, and states that fail secure type cannot be used on any escape routes. Fail-safe releases on loss of power; fail-secure stays locked, which on an escape route is the behaviour that traps people. It is specified by accident more often than anyone would like.
6. Intumescent strips and smoke seals
Clause 7.2.6 makes both a manufacturer obligation rather than an accessory. It is mandatory for the door manufacturer to test and supply insulated doors with intumescent seal, and all fire doors are required to have smoke seal and intumescent seal as standard components of the assembly. Position is specified too: intumescent seals on all three sides of the leaf and on the meeting stile of a double leaf door, or as per test evidence. For smoke, the standard calls for fire rated EPDM or suitable fire rated gaskets.
Part F agrees from the building side, at clause 2.22 Note 3. On installation, clause 9.4.1 flags the failure that ruins a good seal: a self-adhesive strip needs the groove dry and free from dust before it will bond.
7. The four fittings that are not allowed
The standard names them: "Fire door shall not have the following hardware: 1) Tower bolts, 2) Aldrops, 3) Slide bolts, and 4) Chains with pad locks."
Every one of those arrives after handover: an aldrop on a plant room door, a chain and padlock through a pair of exit leaves over a long weekend, a tower bolt to stop a door swinging. The supply chain rarely breaks this rule. Building operations break it constantly, which is why it belongs on a handover briefing and not only in a specification.
Hold-open devices: two clauses read together
IS 3614:2021 permits a fire door to be held open only under electrical supervision. Clause 7.2.9 states that "all hold open devices shall be electrified and should be actuated by active fire and smoke detector", and that mechanical hold-open units are not allowed on fire rated doors. Where a holder is used on a swinging door, it should sit at the top of the door, as close as possible to the lock edge.
Part F is stricter for doors in exits. Clause 2.22 Note 4 states that "Fire doors in exits should not be allowed to be on hold open position and kept closed and to close by 'door closure - spring mechanism'".
Read together the position is workable. On a compartment door away from an exit, a detector-actuated electromagnetic holder is the compliant way to hold a door open for traffic. On a door in an exit, it stays closed on its closer. A wedge, a floor stop or an extinguisher used as a doorstop sits outside both documents.
Where the assembly quietly loses its rating
Certified hardware fitted badly produces an uncertified doorset. The installation clauses close that gap, and they decide most inspections.
- Site fabrication. Doorsets are required to be factory prepared for all hardware, with no work carried out at site. A lock mortice cut on site, or a closer pocket routed in a corridor, is outside the certification. Vision panel apertures should not be cut on site either.
- Clearances. Clause 9.3.1 requires doors to be adjusted to maintain perimeter clearances of a maximum of 3 to 4 mm, and notes a typical gap for good fire performance of 2 mm to 4 mm. The undercut is capped at 19 mm where the door sits on the floor and was tested in that condition; for a door on a sill, clause 7.2.5 puts it at 9 mm.
- Who installs. Clause 9.2.1 expects installation by the door manufacturer or by installers trained in fixing the doorsets, not by a general carpentry subcontractor.
- After handover. Clause 9.6.1 requires periodic inspection, maintenance and repair on a regular basis. Our fire door inspection checklist sets out what to look at and in what order.
What to ask for before a hardware set is approved
- Test evidence that names the hardware. Ask which hinges, closer, lock and seals were on the specimen.
- A certificate per item. Locks, panic devices, lever handles and closers each need type test certification for the specified rating.
- Hinge size and grade in writing. 100 mm x 75 mm x 3 mm minimum in SS 304 or above, or a fire certificate for the hinge.
- A closer label on the body. Not on the cover.
- A fail-safe declaration. For every electrified or electromagnetic lock on an escape route.
- Seal type and position. Intumescent on three sides and the meeting stile, plus the smoke gasket, as per test evidence.
- A door schedule that carries the hardware set. One line per opening, so rating, leaf type and ironmongery travel together to site.
For how the certificates themselves should read, see our guide to verifying fire door certification. For what the rest of the standard covers, start with IS 3614:2021 explained.
Valtrix manufactures IS 3614:2021 certified fire doorsets in Nashik, single and double leaf, in fully insulated, partially insulated, uninsulated and acoustic configurations from FD30 to FD180. The product range and current certification are published in full.
Frequently asked questions
How many hinges does a fire door need in India?
IS 3614:2021 does not state a number. The three-hinge figure quoted online comes from UK practice. Here the count, pattern and fixing are part of the assembly that was fire tested, so the answer for any doorset is the one recorded in its test evidence. What the standard fixes is the threshold below which a hinge needs its own fire certificate: 100 mm x 75 mm x 3 mm in SS 304 or above.
Do fire door hinges need a separate fire certificate?
Only if they fall below that threshold. Clause 7.2.9 exempts hinges of minimum size 100 mm x 75 mm x 3 mm in stainless steel of grade SS 304 and above from the requirement that all hardware be fire rated and certified. A smaller or lower-grade hinge is not exempt. Pull handles in SS 304 or above are treated similarly.
Is a panic bar required on a fire door?
Not on every fire door - it is required where the door is a fire exit. Part F of SP 7:2026 states at clause 2.16 that fire exits should be provided with a panic bar as applicable, and clause 2.38 defines fire exit hardware as a latching assembly that releases on force applied in the direction of egress travel. Where one is fitted, IS 3614:2021 requires a visible certification label on the device.
Can a tower bolt or an aldrop be fitted to a fire door?
No. IS 3614:2021 names tower bolts, aldrops, slide bolts and chains with padlocks as hardware a fire door shall not have. Fitting any of them takes the doorset outside its certification, and it is one of the most common findings on an occupied building.
What is the difference between an intumescent strip and a smoke seal?
An intumescent strip is dormant at room temperature and expands when heated, closing the gap between leaf and frame to maintain integrity during a fire. A smoke seal is a gasket, typically fire rated EPDM, that restricts cold smoke before temperatures rise. IS 3614:2021 requires both as standard components of the assembly, so one cannot be substituted for the other.
Can a fire door be held open?
Only under electrical supervision, and not in an exit. IS 3614:2021 requires all hold-open devices to be electrified and actuated by an active fire and smoke detector, and prohibits mechanical hold-open units. Part F adds that fire doors in exits should not be held open at all. A wedge or a doorstop is not a compliant hold-open device under either document.
