Testing & Certification
Independently tested. Certified to perform.
When seconds matter, there’s no room for guesswork. Every Fire Cloak™ blanket is independently tested, certified, and proven to perform in extreme real-world fire conditions.
Fire Cloak™ goes far beyond theoretical lab testing. Every blanket is subjected to intensive real-world scenarios designed to replicate full lithium thermal runaway events — including:
- Withstands temperatures up to 1,600°C
- High heat flux, flame impingement, and extreme radiant heat
- Rapid deployment under real-life emergency conditions
- Full-scale live burn tests with active EV fires
Setting the standard in EV fire safety.
When it comes to lithium battery fires, there’s no room for guesswork. That’s why Fire Cloak™ is independently tested and certified to DIN SPEC 91489:2024-11, alongside relevant ISO and BSI standards — because lives, businesses, and reputations depend on it.

Fire Cloak™ XL – EV Fire Limitation Blanket (12 x 9m)
DIN SPEC 91489 Test Report (12x9m)
Setting the Global Standard — Tested, Passed and Certified to DIN SPEC 91489:2024-11
Fire Cloak™ is one of the first EV fire blankets in the world to be fully certified to DIN SPEC 91489:2024-11 — the toughest global safety standard for lithium battery fire containment.
Developed by global leaders in fire safety, EV manufacturing, and emergency services, this DIN specification defines the most advanced performance benchmarks for:
- Fire containment performance
- Heat resistance
- Deployment functionality
- Product durability
Live Burn Tested — Real World, Real Fires
At Horiba MIRA (UK), Fire Cloak™ underwent live burn testing on an EV experiencing full thermal runaway:
- Fire temperatures exceeding 900°C
- Blanket successfully deployed and contained the fire within seconds
- Internal fire temperature dropped from 900°C to 47°C in under 10 minutes
