SF 1230™ Fire Protection Fluid:
The 3M™ Novec™ 1230 Replacement
Standard Fluids™ SF 1230™ Fire Protection Fluid is an isomeric drop-in replacement for 3M™ Novec™ 1230 Fluid, produced today by the team that invented and patented the original FK-5-1-12 molecule. It independently holds FM Approval and UL Component Recognition, so whether you’re transitioning off Novec 1230 or specifying new installations, SF 1230 fluid is right for you.

How SF 1230™ Fire Protection Fluid Extinguishes a Fire
Like other halocarbon halon alternatives, SF 1230 fluid extinguishes by removing heat rather than displacing oxygen. Here’s how that happens in a typical fire protection system:
1. Detection
SF 1230 fluid systems use cross-zoned detection: two independent detectors wired to a UL 864-listed releasing panel, so a single false alarm can't trigger discharge. Once both zones confirm, the panel sounds a pre-discharge alarm and holds a short delay for anyone to abort.
2. Discharge
SF 1230 fluid is stored as a liquid and superpressurized with nitrogen. When the panel fires the cylinder valve, the fluid releases through fixed piping and nozzles sized to the hazard.
3. Vaporization
The fluid atomizes into fine droplets and vaporizes almost instantly, mixing with air to reach design concentration in seconds. That vapor mixture carries the highest heat capacity of any commercially available halon alternative, pulling heat out of the fire faster than it can sustain combustion.
For systems designed to a 4.5 vol% concentration under UL 2166, the fire is out within ten seconds.
4. Re-Entry
NFPA 2001 requires the hazard to hold design concentration for a minimum soak time, typically ten minutes, to prevent reflash. To limit the thermal decomposition byproducts of the fluid, systems are designed to detect and extinguish a fire at its incipient stage.
Purity You Can Trace to Each Batch
Every batch of SF 1230™ Fire Protection Fluid is independently tested in the U.S. under an ISO 9001-certified lab framework, backed by a batch-specific Certificate of Analysis, retained samples, and a 20-year SF StratosClear Warranty.
What sets the testing apart is who’s running it. Standard Fluids was founded by the scientists, engineers, and account leaders who built the original 3M™ Novec™ 1230 Fluid business, and SF 1230 fluid is tested against the same methodology they developed for that molecule, including:
- Purity: confirms the batch matches the FK-5-1-12 molecular specification
- Acidity: confirms free acid content stays low enough that it won’t corrode valves, piping, or cylinders
- Water content: confirms dissolved moisture stays within the fluid’s specification
- Stability: confirms the fluid holds its properties under simulated long-term storage
Where SF 1230™ Is Used
SF 1230™ is specified wherever the suppressant itself cannot create a secondary hazard. That includes spaces with active electronics, continuous staffing, or assets that cannot tolerate water or chemical residue.
Data Centers
Server rooms and energized infrastructure require a fire protection fluid that discharges before hardware sustains thermal damage and leaves no residue that could cause costly downtime.
Manufacturing
CNC machines and automated equipment utilize local application fire suppression systems that extinguish cutting fluid and coolant fires without damaging tooling, controls, or the workpiece.
Telecommunications
Equipment rooms and network switching centers need a fire protection fluid that keeps energized equipment online through a suppression event with no residue and no offline window.
Oil & Gas
Offshore platforms and compressor enclosures warrant a fire protection fluid that allows immediate crew re-entry with no decontamination steps or evacuation window.
Medical Facilities
Clean rooms, MRI suites, and laboratory spaces require an occupied-space-rated fire protection fluid that leaves no residue on sensitive equipment or sterile surfaces, saving costly damage to high-value assets.
Marine
Engine rooms and electrical compartments on commercial and military vessels benefit from a non-corrosive, nonconductive fire protection fluid that ships by air for urgent offshore resupply.
Archives & Museums
Sensitive documents, film, and cultural artifacts mandate a waterless, residue-free fire protection fluid that protects irreplaceable collections from the suppressant as much as from the fire itself.
How Fike™ Solved Its Novec™ 1230 Fire Protection Fluid Supply Problem
When 3M™ exited the fluorochemical market, Fike Corporation, one of the largest fire suppression system manufacturers in the world, needed a verified source for the FK-5-1-12 already running in systems installed globally. Fike evaluated alternatives and branded SF 1230™ Fluid as Fike SF 1230™ Fluid, its direct replacement, so installed systems can keep their existing FM Approval and UL Component Recognition without any equipment changes.
SF 1230™ Fire Protection Fluid Frequently Asked Questions
Standard Fluids™ SF 1230™ Fire Protection Fluid is dodecafluoro-2-methylpentan-3-one, ASHRAE designation FK-5-1-12, CAS 756-13-8. It's included in NFPA 2001 and ISO 14520 as a clean agent: electrically nonconductive, colorless, and residue-free on discharge.
Like other halocarbon halon alternatives, SF 1230 fluid extinguishes fire by removing heat, not by displacing oxygen. On discharge, it forms a gas mixture with air that has the highest heat capacity of any commercially available halon alternative, cooling the fire below the temperature it needs to keep burning.
That heat capacity is also why SF 1230 fluid needs a lower concentration to extinguish a fire, just 4.5 vol% for Class A fuels under UL 2166.
Yes, with a wide margin. The NOAEL is 10% by volume, so the safety margin ranges from 69% to 122% above the design concentration. Independent testing found the fluid practically non-toxic during 4-hour acute inhalation, non-irritating to the skin, and not a cardiac sensitizer at the tested exposure levels.
SF 1230 fluid holds UL Component Recognition and FM Approval for use in listed and approved suppression systems. It's included in NFPA 2001 and ISO 14520 under the ASHRAE designation FK-5-1-12. The EPA has also reviewed it under its Significant New Alternatives Policy for use in fire protection.
SF 1230 protects the fires around a battery installation, not the battery itself. In a total-flooding system, SF 1230 fluid extinguishes external Class A, B, and C fires, including electrolyte-leakage fires. That can keep an external ignition source from pushing a battery toward thermal runaway in the first place.
The fluid evaporates completely, leaving no residue and protecting electronics, archives, and precision instruments from a second layer of damage. Its low 4.5 vol% MDC enables systems to catch and extinguish a fire at its incipient stage, thereby limiting decomposition byproducts.
SF 1230 should be stored, sealed and upright, in a clean, dry warehouse, away from heat sources, acids, strong alkalis, and oxidizers.
No. SF 1230 fluid is manufactured, tested, and EPA-reviewed specifically for fire protection use. It's not approved for battery immersion cooling. It's also not approved for medical-supply manufacturing, food-grade products, or cosmetics without prior written permission from Standard Fluids.
If your application falls outside fire protection, our team can tell you whether it's the right fit before you spec it in.
By chemical definition, yes. Fluoroketones contain carbon-fluorine bonds, the basis for the classification. But PFOS and PFOA, the compounds driving most regulatory action, are fully fluorinated carbon chains with no reactive site, which is why they persist and bioaccumulate.
SF 1230 fluid carries a carbon-oxygen double bond instead, a reactive site that breaks down under UV light with a five-day atmospheric lifetime rather than accumulating. That structural difference is why SF 1230 carries a GWP below 1 despite sharing the PFAS classification.
Yes, SF 1230 fluid is a drop-in replacement. It's included in NFPA 2001 and ISO 14520 under the same FK-5-1-12 designation as Novec™ 1230, and its physical properties match closely enough that existing system design calculations don't change.
Full revalidation usually isn't necessary, but some jurisdictions and insurers still want documentation confirming equivalence before they'll sign off. Our team can walk through what your process requires before you transition.
