28、ules of design, type testing and inspection during manufacturing, ratings and classification of mobile fire extinguishers and test methods to be used. It applies to mobile fire extinguishers with a total mass above 20 kg for powder, water based and CO2extinguishers. This standard applies to mobile f
29、ire extinguishers that are manoeuvred by an operator on foot only. It does not cover fire tests for class C and class F fires, but the used extinguishing media can be effective on these types of fire. Class D fires are considered to be a very specialist application and are not included in this stand
