IEC 61400 is an International Standard published by the International Electrotechnical Commission regarding wind turbines. ==Purpose and function== The 61400 is a set of design requirements made to ensure that wind turbines are appropriately engineered against damage from hazards within the planned lifetime. The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested,〔Woebbeking, Mike. ("IEC TS 61400-22" ) pages 1-2 and 9 ''Germanischer Lloyd'', 2008. Accessed: 12 March 2011.〕 assembled and operated. Wind turbines are capital intensive, and are usually purchased before they are being erected and commissioned. Some of these standards provide technical conditions verifiable by an independent, third party, and as such are necessary in order to make business agreements so wind turbines can be financed and erected.〔 IEC started standardizing international certification on the subject in 1995, and the first standard appeared in 2001.〔 The common set of standards sometimes replace the various national standards, forming a basis for global certification.〔 Small wind turbines are defined as being of up to 200m2 swept area and a somewhat simplified IEC 61400-2 standard addresses these. It is also possible to use the IEC 61400-1 standard for turbines of less than 200m2 swept area. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IEC 61400」の詳細全文を読む スポンサード リンク
