14、n (dow) 2011-05-01 This European Standard has been prepared under Mandate M/349 given to CEN and CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 90/396/EEC (see Annex ZZ, which is an integral part of this document). The ess
15、ential requirement of EC Directive 90/396/EEC relating to “rational use of energy“ is defined by the maximum quantity of energy recovered (thermal and electrical energy output) from the gas energy input. This European Standard deals with a very early state of new technology. The requirements of this
16、 European Standard are not intended to constrain innovations. When considering materials, designs or constructions not specifically dealt with in this European Standard the alternatives shall be evaluated as to their ability to yield levels of safety and performance equivalent to those prescribed by
17、 this European Standard. This can be done by a risk assessment. Furthermore not all requirements could be described in detail up to now. This is valid both for the requirements and the test procedures. This will be done in later revisions of this European Standard. Guidance to fuel cell stacks and t
18、heir performance may be found in EN 62282-2. Due to the development of new technology other solutions than those described in this standard are possible if these solutions provide at least an equivalent level of safety. Matters related to quality assurance systems, tests during production, and certi
19、ficates of conformity of auxiliary devices are not dealt with in this European Standard. _ BS EN 50465:2008 Licensed CopyChinese University of Hong Kong, 11/04/2009 09:19, Uncontrolled Copy, (c) BSI 3 EN 50465:2008 Contents 1 Scope . 6 2 Normative references . 6 3 Definitions . 8 4 Classification 23
