This Indian Standard was adopted by the Indian Standards Institution on 27 May 1966, after the draft finalized by the Fire Safety Sectional Committee had been approved by the Civil Engineering Division Council. 

 One of the fire safety requirements to be taken into consideration while planning and designing industrial and non-industrial buildings is to provide the means for restricting the spread of fire, both internally and externally. The spread of fire can be minimized if the respective floor areas are limited and divided into smaller sections, each section being separated by perfect separating walls and openings therein fitted with fire-check doors. The design of fire-check doors and the materials to be used in their construction have to be such that the doors shall be capable of providing an effective barrier to the spread of fire. The fire resistance of two doors should, as far as practicable, be the same as for the wall. This standard has been prepared with a view to providing adequate guidance to both the manufacturer and the user in regard to the materials to be used and the construction to be adopted for fire-check doors capable of giving the required fire protection. 

As erection of fire-check doors Is a very important aspect in order to achieve the desired degree of fire protection, it is strongly advised that the fire check doors should be erected strictly in accordance with the requirements given in Appendix A of this standard. 

In the formulation of this standard due weightage has been given to international co-ordination among the standards and practices prevailing in different countries in addition to relating it to the practices in the field in this country. 

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated. Providing and fixing of Hollow metal fire rated doors as per IS 3614 part-1 & part-2 for stability and integrity. Pressed Galvanized steel confirming to IS 277 with the following specification.

Recommended fire door shall have doors tested at CBRI or ARAI for maximum rating of 2hrs with vision panel. Test certificates should be available for vision lites /panels as part of the fire door assembly. Independent glass test certificates will not be accepted. Manufacturer test certificate shallcover doors both single and double leaf and all doors supplied should be within the tested specimen,deviation in specification and sheet thickness other than what is mentioned in the test certificates are not allowed. Proper label confirming the type of door and the hourly rating is mandatory. Approved manufacturer Shakti Hormann or approved equivalent.

Door frame shall be double rebate profile of size 143 x 57 mm made out of 1.60mm (16gauge) minimum thick galvanized steel sheet. Frames shall be Mitered and field assembled with self tabs. All provision should be mortised, drilled and tapped for receiving appropriate hardware. Rubber door silencers should be provided on the striking jamb. Frames should be provided with back plate bracket and anchor fasteners for installation on a finished plastered masonry wall opening. Once frame installed should be grouted with cement & sand slurry necessary for fire doors on the clear masonry opening. Door leaf shall be 46mm thick fully flush double skin door with or without vision lite. Door leaf shall be manufactured from 1.2mm (18guage) minimum thick galvanised steel sheet. The internal construction of the door should be rigid reinforcement pads for receiving appropriate hardware. The infill material shall be resin bonded honeycomb core. All doors shall be factory prepped for receiving appropriate hardware and provided with necessary reinforcement for hinges, locks, and door closers.
