A practical overview of how SP 7:2026 Part F affects door ratings for shafts, exits and compartment boundaries.
From NBC 2016 to NBCS 2026
The National Building Construction Standards 2026 (SP 7:2026) supersede NBC 2016 for many project references in India. Part F - Fire and Life Safety - remains the primary driver for passive fire product selection.
For fire doors, the practical question is unchanged in spirit: where does the code require integrity, stability and insulation, and for how long?
Shafts, exits and lobbies
Firefighting shafts, pressurised lobbies and protected exits continue to demand high integrity performance - often 120 minutes at critical openings.
Specifiers should map every door location to the relevant clause rather than applying a single rating across the building.
What to ask your manufacturer
Request CBRI / NABL test evidence against IS 3614:2021, BIS licence number where applicable, and clear schedules matching door types to locations.
