On August 1, the State Administration for Market Regulation (SAMR) and the Standardization Administration of China (SAC) officially released GB 45944-2025, “Perfluorohexanone (FK5-1-12) Clean Agent Fire Extinguishing Systems.” This new national standard is mandatory, and will be included in the government’s annual standardization plan and will come into full effect on August 1, 2026, setting standards for the product quality and safety in application.
Perfluorohexanone (FK5-1-12) is recognized for its excellent extinguishing performance, environmental safety, and zero residue—making it suitable for protecting electrical equipment, precision devices, data centers, and high-value assets. The new standard clarifies the technical specifications, safety indicators, and system requirements for FK5-1-12-based fire suppression systems. By setting unified benchmarks, it strengthens regulatory oversight and promotes the high-quality development of the clean-agent fire protection industry.
The new National Standards specified multiple key indexes, including purity, suppression performance and so on. The new Standards aim to standardize the full chain from production to application, covering production, quality control, and end use. Standardization provides clear references to manufacturers as well as downstream users.
As 3M had discontinued production of Novec 1230, new manufacturers emerged to reassure the legacy market of Novec. The standardization is significantly meaningful for manufacturers and users, that FK5-1-12 products will be not only a chemically equivalent, but also progressing towards qualification and meeting international standards.
As a core supplier in China’s fluorochemical and clean-agent sector, Yonghe Group produces FK5-1-12 using a fully integrated fluorochemical process. The product features high purity, stable performance, and strict environmental compliance. With advanced manufacturing capabilities and a complete supply chain, the company aims to support the transition toward safer, greener, and more efficient clean-agent solutions.
