Verified Reaction-to-Fire Performance for Fire Cloak™ EV Fire Blankets
BS EN 13501-1:2018 provides the harmonised European method for classifying how materials behave when exposed to developing fire conditions. It assesses ignition, flame spread, heat release, smoke generation and the presence of flaming particles — offering a structured, evidence-based picture of fire-reaction behaviour.
Through accredited testing, Fire Cloak™ blankets have achieved certified reaction-to-fire classifications under this framework. The CFB2186B model is rated A2-s1,d0, reflecting very limited combustibility and minimal smoke production, while the CFB1209 model is rated B-s2,d0, showing low heat release and no flaming droplets. These results underline Fire Cloak™’s proven fire-reaction characteristics and its suitability for managing EV-related fire risks.
How Fire Cloak™ Meets BS EN 13501-1:2018
Fire Cloak™ EV Fire Limitation Blankets have been assessed using the harmonised reaction-to-fire methods required for BS EN 13501-1:2018. These tests examine how a material behaves in the early development of a fire, measuring heat release, smoke generation, flame spread, and the presence of flaming droplets.
Both Fire Cloak™ blanket fabrics were tested by accredited laboratories and classified accordingly. The heavier-duty CFB2186B model achieved A2-s1,d0, indicating very limited combustibility, exceptionally low smoke output and no flaming droplets. The CFB1209 model achieved B-s2,d0, confirming low heat release, controlled smoke behaviour and the absence of flaming droplets during exposure.
These classifications demonstrate that Fire Cloak™ blankets react in a predictable and controlled manner when exposed to heat and flame — an essential characteristic when containing or limiting EV fires in confined, public or industrial environments.
BS EN 13501-1:2018 Test Reports
Each Fire Cloak™ blanket model is supported by a dedicated BS EN 13501-1:2018 classification report issued by an accredited European testing laboratory. These reports document the full series of reaction-to-fire tests required for classification, covering heat release, flame spread, smoke development and flaming droplets.
Both reports include complete traceability — identifying the product tested, construction, conditioning, test dates, laboratory accreditation and direct references to the relevant clauses of EN 13501-1:2018.
For full transparency, the complete BS EN 13501-1:2018 classification reports for both blanket models are provided below for download.

What This Means in Practice
Fire Cloak™’s certified reaction-to-fire performance offers tangible advantages for teams working around EVs, from emergency responders and recovery operators to insurers and facilities managers. The classifications achieved under BS EN 13501-1:2018 demonstrate stable, predictable behaviour under defined fire conditions — a critical factor when planning procedures, assessing risk or selecting equipment.
Below is a sector-specific breakdown of how Fire Cloak™’s classification translates into real-world operational value.
Certified Proof & Next Steps
Fire Cloak™ performance under BS EN 13501-1:2018 is supported by formal, accredited reaction-to-fire reports issued by FIRES, s.r.o. and partner laboratories. Each blanket fabric was tested separately, with the laboratories assessing heat release, flame spread, smoke output, flaming droplets and (for the A2 classification) calorific potential.
These assessments confirm that Fire Cloak™ materials exhibit controlled, predictable reaction-to-fire behaviour: the CFB2186B model achieves A2-s1,d0, showing very limited combustibility and minimal smoke generation, while the CFB1209 model achieves B-s2,d0, demonstrating low heat release and no flaming droplets. This evidence provides a robust, independently verified foundation for operational decisions, risk assessments and insurance discussions.
