IS 3614 is the Indian Standard for fire-check doors, covering their construction, testing and performance. The 2021 revision modernised the standard, aligning its fire-resistance testing approach with current practice. In India, fire-door requirements for a building flow from the National Building Code and the local fire authority — IS 3614 is the standard those authorities reference for what a fire door must be.

When a project specifies fire doors to IS 3614, the key parameters are the fire-resistance duration (commonly 60 or 120 minutes for compartmentation), integrity and insulation performance, and the tested assembly — leaf, frame, seals and hardware together. A fire rating applies to the complete assembly as tested, never to a leaf alone.

Egis' FireShield H60 is tested to EN 1634-1 (the European fire-resistance test for doors) achieving EI60. For Indian projects, Egis maps EN-tested performance to the IS 3614 framework and advises on the approval path with the authority having jurisdiction — because what matters on site is not the certificate's origin but its acceptance by the approver.

The National Building Code of India (NBC 2016), Part 4 — Fire and Life Safety — sets the framework for compartmentation, escape routes and fire-door provision in Indian buildings. It defines where fire separations are required, what ratings they need, and how doors in escape routes must behave (self-closing, smoke-sealing, unobstructed).

For door specification, NBC 2016 matters in two ways: it drives which walls need fire doors and at what rating, and it sets expectations for door hardware on escape routes. Hospital projects additionally navigate NABH accreditation requirements, which reference controlled environments and infection control — the domain of hermetic doors.

Egis supports NBC-driven specification by mapping each door in the schedule to its required performance: fire rating where the Code demands compartmentation, smoke rating where escape routes need tenability, and airtightness where clinical or clean-room function demands it.

ISO 14644 is the international standard series for cleanrooms and associated controlled environments. Part 1 classifies air cleanliness by particle concentration (ISO Class 1–9); other parts cover testing, monitoring and operational discipline. Pharma facilities in India design to ISO 14644 alongside Schedule M / GMP requirements.

Doors affect classification in two ways: they must not shed particles themselves (flush, sealed, non-shedding surfaces), and they must protect the pressure cascade between grades (sealed perimeters, interlocked airlocks). A door with applied trims, exposed cores or leaky perimeters is a classification risk regardless of how well the HVAC performs.

Egis' clean-room range — PureSwing and PureSlide hygienic doors with interlocked airlock pairs — is detailed for ISO 14644 environments: flush faces, sealed edges, stainless hardware, and airlock logic that protects the cascade. For Grade B and sterile areas, the HermaSeal Class 4 hermetic range provides the tightest envelope.

EN 1026 is the test method for air permeability of windows and doors; EN 12207 classifies the result from Class 1 to Class 4, with Class 4 the tightest. The test measures air leakage at defined pressure differentials — it is a measurement, not a claim.

For hermetic doors, Class 4 is the meaningful target: it means the door leaks the least air of any classified operable door, which is what operating theatres, isolation rooms and cleanrooms need to hold their pressure cascades. Egis' HermaSeal range is type-tested to EN 1026 and achieves Class 4 under EN 12207.

Note the distinction from smoke testing (EN 1634-3) and fire testing (EN 1634-1): a door can be airtight without being fire-rated, and fire-rated without being airtight. The FireShield H60 is both, tested to each standard for its respective performance.

EN 13241 is the European product standard for industrial, commercial and garage doors, covering safety in use: crushing, shearing and impact hazards, and the safety devices that mitigate them. It is the reference standard Egis designs its powered industrial doors to.

In practice this means the RapidRoll R600 high-speed door carries layered safety — presence detection, light curtains, soft bottom edges — as designed-in systems rather than add-ons, and that the safety logic is commissioned, not assumed.

EN 16005 is the European safety standard for powered pedestrian door sets — the automatic sliding doors in hospital entrances, clean corridors and commercial lobbies. It defines the required safety functions: presence detection, force limitation, and safe behavior on power failure.

Egis' automatic sliding doors — healthcare, clean-room and commercial — are specified with safety to EN 16005: radar and infrared activation with presence detection, force-limited drives, and defined safe states. Safety is commissioned on site as part of installation.

In India, X-ray installations are regulated by the Atomic Energy Regulatory Board (AERB). Room shielding — including doors — follows the shielding design prepared under AERB guidelines, accounting for equipment workload, energy, layout and occupancy.

The door's role is to provide its specified lead equivalence (typically 1–3 mm Pb) with no gaps at the frame, and to interlock with the room's warning and exposure circuits. Egis' RadGuard X3 is built to the specified equivalence and provides the door-closed proving output that radiation safety design requires.
