ICS 13.220.10                         CED 22

Revised Standard from Last Update.

1 SCOPE

This standard specifies provisions and recommendations for general requirements, type of clean agents and their containers, container arrangement, distribution systems, such as piping, nozzles, pipe supports, alarm system, type of enclosure, etc.

NOTES

1 This standard covers the general requirements applicable to total flooding clean agent systems like halo-carbon agents and inert gas agents. In addition, individual requirements for each type of clean agent system are covered under separate standards, namely IS 15497, IS 15501, IS 15505, IS 15506, IS 15517, IS 15525, IS 15821 and IS 15835. Detailed design guidelines are specified in these standards. Hence, before designing a protection with a particular clean agent, both the standards should be read together. Wherever there is a difference, the individual standard takes precedence.

2 This standard prescribes minimum requirements for total flooding clean agent fire extinguishing systems. Protection with carbon dioxide is not covered in this standard for which IS 15528 may be referred.
