You find that each standard uses different methods to test panels. EN 13501-1 focuses on how materials react to fire and classifies them by combustibility, smoke, and droplet formation. ASTM E84 and UL 723 measure how fast flames and smoke spread across surfaces. NFPA 285 checks how wall systems perform in real fire scenarios, especially for tall buildings.
Fire Rating Classes Explained (A1, A2, B, A+, B1)
You see fire rating classes like A1, A2, and B when you look at composite honeycomb panel specifications. These classes tell you how well a panel resists fire, smoke, and flaming droplets. The table below explains what each class means:
| Fire Rating | Combustibility | Smoke Emission | Droplet Formation | Typical Application |
|---|---|---|---|---|
| Class A1 | Completely non-combustible | Negligible smoke | No flaming droplets | Aluminium, steel, concrete, mineral wool |
| Class A2 | Limited combustibility (non-combustible core) | s1 – minimal smoke | d0 – no droplets | fire-rated A1 honeycomb panels for facades |
| Class B | Low combustibility | s1 – limited smoke | d0 – no droplets | fire-rated A1 honeycomb panels for interiors |
You want fr a1-rated honeycomb panels for the highest level of fire safety. Class A1 panels do not burn or produce dangerous smoke. Class A2 panels have a non-combustible core and also limit smoke and droplets. Class B panels offer some protection but may not meet the strictest international safety standards.
How Ratings Apply to Composite Honeycomb Panels
You need to know how these ratings work in real building projects. Testing labs check composite honeycomb panels for fire resistance, peel strength, and thermal performance. You see panels rated by how long they withstand fire and how much smoke they produce. The table below shows how standards apply in practice:
