This standard specifies the requirements for material, design, construction, anti-corrosive treatment, and performance testing of cartridge-type dry powder portable fire extinguishers. It has been largely superseded by IS 15683 for new manufacturing but remains important for maintaining legacy equipment.

Practical Notes
IS 15683 has replaced this standard for new fire extinguisher manufacturing and standardizes rating requirements.
Ensure the dry powder used for refilling conforms to IS 4308 to guarantee specified fire rating performance.
Gas cartridges must be regularly weighed to detect any leakage over time as per maintenance schedules.
