This standard specifies the requirements for materials, construction, anti-corrosive treatment, and performance testing of 9-litre portable water-type fire extinguishers operated by a gas cartridge. It is primarily used by safety engineers and manufacturers, though it has been largely superseded by IS 15683 for newer equipment.
Specification for Portable Fire Extinguisher, Water Type (Gas Cartridge)
Quick Reference Values
Nominal capacity9 Litres
Minimum effective range of throw6 meters
Discharge time limits60 to 120 seconds
Hydraulic test pressure for body3.5 MPa (35 kgf/cm2)
Gas cartridge capacity (CO2)60 grams
Percentage of discharge requiredNot less than 95%
Practical Notes
Always verify the weight of the gas cartridge during routine maintenance; if it loses more than 10% of its initial mass, it must be replaced.
The anti-corrosive inner lining (often lead-tin alloy or plastic) is critical to prevent the steel body from rusting due to constant water contact.
This standalone standard has been technically replaced by IS 15683, which unified specifications for all portable fire extinguishers in India.
