UL 711-2004灭火器的等级和灭火试验

1.1 These requirements cover rating, and performance during fire tests, of fire extinguishers intended for use in attacking Class A, B, C, D, and K fires as defined herein. These requirements also cover performance during fire tests of fire extinguishing agents for application on Class D fires. The ultimate rating of an extinguisher or the prescribed use of an extinguisher or fire extinguishing agent is based on its fire-extinguishing potential as determined by fire tests and presupposes installation and use in accordance in the United States with the Standard for Portable Fire Extinguishers, NFPA 10, and with the National Fire Code of Canada. 1.2 Fire extinguishers, fire extinguishing agents, or both shall also comply with the requirements for construction and performance as applicable to specific types, designs, sizes, and arrangements. Such additional requirements are not within the scope of these requirements.

DIN EN 3-7-2007便携式灭火器.第7部分:特性、性能要求和试验方法

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.
