Compliance overview
Scope and applicability
This standard applies to the research and development, production, and inspection of water based extinguishing agents. It specifically covers agents formulated by adding additives such as penetrants and flame retardants to water. It is not applicable to foam extinguishing agents or dry chemical powders. Manufacturers of fire safety equipment must ensure their water-based products comply with these updated regulations.
Technical requirements
The standard specifies comprehensive physical and chemical requirements for both the original solution and the mixed solution of the extinguishing agent. Key parameters include freezing point, pH values, and sediment volume, which must remain within defined tolerances before and after temperature treatment. Manufacturers must declare characteristic values for freezing points and Class A fire ratings. A major focus of this revision is the introduction of biological and environmental safety requirements. The standard mandates testing for fish acute toxicity, acute oral toxicity in mice, and eye irritation in rats, categorizing the agents into Tier 1 and Tier 2 based on toxicity levels. Compliance with these eco-toxicological parameters is mandatory for market access. Additionally, the standard outlines requirements for material compatibility and performance. It sets strict corrosion rate limits for Q235A steel and 3A21 aluminum. Performance metrics such as permeability and Class A fire extinguishing performance (minimum 1A rating) are also rigorously defined to ensure operational reliability.
Testing methods
The standard mandates a series of rigorous evaluation procedures, including temperature cycling tests (freeze-thaw stability) to assess long-term storage viability. Chemical and physical tests measure freezing point, pH, and sediment volume. Specific biological tests using zebrafish, mice, and rats are required to evaluate acute toxicity and eye irritation. Furthermore, corrosion rate tests using metal coupons and fire suppression tests using portable extinguishers are conducted to verify real-world performance.
FAQs
What products are regulated under GB 17835-2024?
This standard regulates water based extinguishing agents, which are formulated by adding additives such as penetrants and flame retardants to water to improve fire suppression performance. It applies to the R&D, production, and inspection of these agents.
Are there any updates from the previous version of GB 17835?
The 2024 version introduces new requirements for stability, acute oral toxicity, eye irritation, and permeability. It also adds technical requirements for the original solution's freezing point, pH, and corrosion rate, while removing the requirements for surface tension and Class B fire extinguishing performance found in the 2008 version.
How does GB 17835-2024 relate to other fire safety standards?
The standard references several Chinese standards, such as GB 4351 for portable fire extinguishers and GB 15308 for foam extinguishing agents. Manufacturers must ensure their testing protocols align with these referenced GB standards when demonstrating compliance.
