Based on recent Underwriters Laboratories Inc. (UL) and FM Approvals “witnessed” testing, the minimum Class A extinguishing concentration for 3M™ Novec™ 1230 Fire Protection Fluid was reduced from 3.5% to 3.3% for all systems that meet the minimum average nozzle pressure of 74.4 psi. Because the design concentration for Class A hazards is directly impacted by the heptane cup burner values, the test result will not impact the design concentration for Class A hazards.
The testing, however, will reduce the minimum design concentration for National Fire Protection Association (NFPA) 2001 Class C energized hazards from 4.7% to 4.5%,* resulting in a potential 4.25% reduction in the amount of agent required for Class C hazards.
The reduction in Novec 1230 fluid extinguishing concentration is the direct result of 3M’s efforts to validate the fluid’s efficiency and performance – just one more reason to choose the sustainable, smart solution: 3M™ Novec™ 1230 Fire Protection Fluid.
Unlike the potent greenhouse gases HFC-227ea (Chemours’ FM-200™) or HFC-125 (Chemours’ FE-25™), Novec 1230 fluid is not targeted for phase-down under the European F-gas regulation and is not subject to the global HFC phase-down under the Kigali Amendment to the Montreal Protocol. Also, under the Significant New Alternatives Policy (SNAP) Program, the U.S. Environmental Protection Agency (EPA) has proposed a status change for HFCs sold into various industry sectors.
• 3.3% x 1.35 = 4.5% - Class C minimum design concentration is 1.35 times the Class A minimum extinguishing concentration (UL 2166, UL 2127).
