This standard specifies requirements relating to protective apparel and materials used to protect the wearer against occasional and short-term contact with small flames in conditions without thermal risk.
Product performance is determined in accordance with its behaviour when exposed to a small flame for 10 seconds.
The material’s performance level is defined using the following requirements (index 3 being the highest level):
| Flame spread | Flaming debris | Hole formation | After-glow | After-flame | |
|---|---|---|---|---|---|
| Index 1 | No flame spread | No spread of flaming debris | Hole formation permitted | ≤ 2s | After-flame permitted |
| Index 2 | No holes > 5mm | ||||
| Index 3 | No holes > 5mm | ≤ 2s |
Test performed in our laboratory.
Our far-reaching lab work and extensive testing simplify your certification procedures, by saving time and improving reliability.
This involves measuring the limited flame spread properties of vertically oriented nonwovens when exposed to a small flame. This test method is used to classify materials into three performance levels using the following criteria:
