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.

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.
