适用范围： This standard specifies the characteristics, performance requirements and test methods for portable fire extinguishers. Reference to the suitability of an extinguisher for use on gaseous fires (class C fires) are at the manufacturer's discretion, but are applied only to powder type extinguishers which have gaDned a class B or class A and class B rating. Suitability of extinguishers for use on class D fires (fires involving flammable metals) is outside the scope of this standard in respect of test fires. However, extinguishers claiming class D suitability are covered in all other respects by the requirements in this standard for powder extinguishers. It is considered hazardous for powder and carbon dioxide fire extinguishers to be used on Class F fires. Forthis reason powder and carbon dioxide fire extinguishers are excluded for conformance with regard to Class F inthis European Standard. NOTE The extinction of a metal fire presents a situation so specific (in terms of the metal itself, its form, the configuration ofthe fire etc.) that it is not possibre to define a representative standard fire for the purposes of testing. The efficiency ofextinguishers on class D fires needs to be established on a case by case basis.
