The Chinese government has released a draft standard for perfluorohexanone fire extinguishing agent for public comment. The standard, which is expected to be finalized in 2024, will establish technical requirements for the purity, impurity content, water content, acidity, non-volatile residue, and suspended or precipitated matter of perfluorohexanone fire extinguishing agent.
The draft standard requires perfluorohexanone fire extinguishing agent to have a purity of at least 99%. The maximum allowable content of impurities, including perfluoro-2-methyl-2-pentene and HF adduct, is 90 mg/kg. The maximum allowable content of perfluoro-4-methyl-2-pentene is 1000 mg/kg. The maximum allowable water content is 10 mg/kg. The maximum allowable acidity is 3 mg/kg. The maximum allowable non-volatile residue is 0.03%. Suspended or precipitated matter must be invisible.
The draft standard also includes requirements for sampling, testing, marking, filling, storage, and transportation of perfluorohexanone fire extinguishing agent.
The public comment period for the draft standard will end on September 30, 2023. Comments can be submitted to the China National Standardization Administration (CNSA) website.
The new standard is expected to improve the quality and safety of perfluorohexanone fire extinguishing agent. It will also help to ensure that the product meets the requirements of international standards.
The standard is expected to be implemented in 2024.
