IS 8090:1976 is the Indian Standard (BIS) for couplings, branch pipe, and nozzle used in hose reel tubing for fire fighting. This standard specifies the material, dimensional, construction, and performance requirements for couplings, branch pipes, and nozzles used with hose reel tubing for firefighting. It ensures that these critical components are robust, reliable, and interchangeable for effective first-aid firefighting operations.
Specification for Couplings, Branch Pipe, and Nozzle Used in Hose Reel Tubing for Fire Fighting
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! This standard applies specifically to hose reel tubing assemblies (typically 19mm or 25mm diameter), not to be confused with the larger fire hose delivery couplings covered by IS 903.
! Always verify that the manufacturer provides material test certificates confirming compliance with the specified material grades (e.g., LTB 2 of IS 318 for gunmetal).
! During inspection, check for the BIS certification mark on the product, as it is a mandatory requirement for these items.

Key Differences
≠IS 8090 is a component-level standard focusing only on the coupling, branch pipe, and nozzle, whereas modern equivalents like EN 671-1 are system-level standards covering the entire hose reel assembly (reel, hose, nozzle, mounting).
≠IS 8090 is highly prescriptive about materials (e.g., Leaded Tin Bronze Grade LTB-2), while EN 671-1 is performance-based, allowing any material (including polymers and composites) that passes specified strength, aging, and corrosion tests (e.g., 240-hour salt spray test).
≠Modern standards like EN 671-1 use the 'K-factor' (discharge coefficient) to define nozzle hydraulic performance, which is a more precise engineering metric. IS 8090 uses a less precise method of specifying a minimum flow rate (LPM) at a single reference pressure.
≠The performance requirements in IS 8090 are generally lower than current international standards. For example, the required jet throw in IS 8090 is 6 meters, whereas EN 671-1 requires a 10-meter effective range.
Key Similarities
≈All standards mandate the core function of a controllable shut-off nozzle for first-aid firefighting applications.
≈Both IS 8090 and its international counterparts require the nozzle to be capable of producing both a solid jet for range and a spray pattern for wider coverage and cooling.
≈A mandatory hydrostatic pressure test is a fundamental requirement across all standards to ensure the pressure-bearing components (nozzle body, couplings) are free from leaks and can withstand operational pressures.
≈All standards require the use of durable, corrosion-resistant materials to ensure reliability and a long service life, although the method of specifying these materials differs (prescriptive vs. performance-based).
