Extinguishing Media & Powder Verification BodyKey Objectives of ISO 7202:2018
Rigorous criteria established to guarantee extinguishing media efficacy, compatibility, and compliance:
Define Performance Criteria
Sets requirements for extinguishing efficiency, flowability, moisture resistance, and chemical stability.
Standardize Test Methods
Establishes uniform procedures to evaluate extinguishing effectiveness, compatibility, and discharge characteristics.
Ensure Safety and Quality
Promotes the production of high-quality extinguishing powders that perform reliably in real-world conditions.
Support Regulatory Compliance
Helps manufacturers and users meet national and international fire safety standards.
Applications of ISO 7202-Compliant Powders
High-performance dry chemical powders deployed across mission-critical fire safety sectors:
Portable Fire Extinguishers
Portable fire extinguishers (ABC and BC types) for rapid containment of Class A, B, and C hazard fires.
Mobile Firefighting Units
Wheeled extinguishing units and mobile firefighting apparatus requiring high-volume powder discharge.
Fixed Suppression Systems
Fixed suppression systems installed in manufacturing plants, industrial facilities, and processing lines.
Fuel Storage & Flammable Liquid Sites
Protection of fuel storage areas, chemical handling depots, electrical equipment rooms, and flammable liquid sites.
Aviation, Marine & Transport
Comprehensive fire safety coverage across commercial aviation, marine vessels, railway networks, and transport fleets.
