EN 1866 applies to mobile fire extinguishers with a total mass above 20kg for powder, water based and CO2 extinguishers and manoeuvred by an operator on foot only.

Class D fires are considered to be very specialist application and are not included.

Caution: To be sure of reliable, proven, performance of the fire extinguisher in fire condition, the extinguisher should carry independent proof of performance, such as the LPCB mark, and if it is to be supplied into the EU the additional CE mark will also be required as defined by PED.  

Always follow manufacturers use, installation and servicing instruction and replace after use.
