LIMITED FLAME SPREAD PROTECTION

EN ISO 14116

> Supersedes EN 533

This protective clothing is intended to protect workers against occasional brief contact with small flames. The working circumstances offer no significant heat hazard and there is no presence of another type of heat.

Index 1 = the flame does not spread, there are no flaming debris, no after glow, a hole may be formed
Index 2 = the flame does not spread, there are no flaming debris, no after glow, no hole formation
Index 3 = the flame does not spread, there are no flaming debris, no after glow, no hole formation, and the after flame time of each individual specimen is less than 2 seconds

In Detail:
European standard for garments where there is risk of ignition. The garment should be used with a jacket and trousers or coverall made from flame-retardant fabric approved in accordance with EN ISO 11612, in order to give the intended protection. The garment is not designed for protection against convective heat, radiant heat or molten metal and similar hazards.

Design Demands:
- 20cm overlap jacket and trousers
- No turn-ups
- Thermally conductive material that is likely to be exposed to heat shall not be in contact with the skin when the garment is closed

Fabric Demands ISO 15025:
Demands for mechanical strength and for flame and heat resistance are defined according to three Index levels, with Index 3 being the highest.

Index 1
• No specimen shall give flaming to the top or either edge
• No specimen shall give off flaming debris
• No afterglow shall spread after the cessation of flaming

Index 2

Index 3
Same as Index 1, and in addition:
