The Euroclass fire rating system is used across Europe to classify how materials react to fire. It is defined under EN 13501-1, and is more detailed than many other fire rating systems.
What is Euroclass?
Euroclass categorizes materials from A1 (non-combustible) to F (no performance determined).
Main classification levels:
- A1: Non-combustible
- A2: Very limited combustibility
- B–D: Increasing levels of fire contribution
- E: Limited performance
- F: No fire performance data
What does B-s1,d0 mean?
One of the most commonly specified Euroclass ratings is B-s1,d0.
Breakdown:
- B = limited contribution to fire
- s1 = very low smoke production
- d0 = no flaming droplets
What it means:
This is considered a high safety performance level for interior materials, especially in public buildings.
Euroclass vs other systems
Unlike ASTM systems that focus mainly on flame spread, Euroclass also evaluates:
- Smoke production (s1–s3)
- Flaming droplets (d0–d2)
This makes it more detailed and stricter in some applications.
Final thoughts
Understanding the Euroclass fire rating system is essential when selecting materials for modern interior and architectural applications. Ratings such as A1, A2, and B-s1,d0 are not just technical labels—they directly reflect how a material behaves in a fire scenario, including its combustibility, smoke production, and risk of flaming droplets.
