IS 16703:2017 is the Indian Standard (BIS) for automatic sprinkler systems - design, installation, and maintenance - code of practice. This standard provides the code of practice for the design, installation, and maintenance of automatic fire sprinkler systems. It outlines requirements for hazard classification, system components, hydraulic calculations, water supplies, and acceptance testing to ensure the effective operation of sprinkler systems for life safety and property protection.
Lays down requirements for the planning, design, installation, acceptance testing, operation, and maintenance of automatic sprinkler systems.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
