This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2008, and conflicting national standards shall be withdrawn at the latest by Febru

19、ary 2008. This document supersedes EN 1866:2005. This standard consists of the following parts under the general title “Mobile fire extinguishers“: Part 1: Characteristics, performance requirements and test methods Part 2: Additional requirements to EN 1866-1 for the construction, resistance to pres

20、sure and mechanical tests for extinguishers with a maximum allowable pressure equal to or lower than 30 bar 1) Part 3: Additional requirements to EN 1866-1 for pressure resistance of CO2extinguishers 1).

EN 1866-1:2007 (E) 5 1 Scope This European Standard specifies the rules of design, type testing and inspection during manufacturing, ratings and classification of mobile fire extinguishers and test methods to be used. It app

23、lies to mobile fire extinguishers with a total mass above 20 kg for powder, water based and CO2extinguishers. This standard applies to mobile fire 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 med

24、ia 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 standard, but may be made the object of national specification. 2 Normative references The following referenced documents are indispensable for the application of
