Is this standard still in use for new projects?

No, the production and new installation of Halon systems are banned under the Montreal Protocol. This standard is for quality assurance of existing or recycled Halon for critical applications only.

What is the minimum required purity for Halon 1301?

99.6% by mass, as specified in Table 2.

What is the key difference in application between Halon 1211 and 1301?

Halon 1211 is a liquid streaming agent used in portable extinguishers, whereas Halon 1301 is a gaseous agent used in fixed total-flooding systems for unoccupied spaces.

What test is used to determine water content?

The Karl Fischer method is specified in Annex B for determining water content.

This standard specifies the quality requirements for Halon 1211 and Halon 1301, used as fire extinguishing media. It defines the necessary purity levels, maximum allowable impurities (like water and acidity), and methods for testing and sampling. The use of these substances is heavily restricted due to their ozone-depleting properties under the Montreal Protocol.

Practical Notes

Halons are ozone-depleting substances and their production for non-critical use is banned globally. This standard is now relevant only for quality control of recycled halon or for maintaining legacy critical-use systems (e.g., aviation).

Halon 1211 is a liquid streaming agent primarily for portable extinguishers, while Halon 1301 is a gaseous agent for total flooding systems.

Modern fire suppression systems use environmentally friendly 'clean agent' alternatives like HFCs (IS 15517), FK-5-1-12 (IS 16018), or inert gases.
