International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 61400-2:201X
Title Wind turbines - Part 2: Small wind turbines
Project Number 24413
Abstract/Scope IEC 61400-2:2013 deals with safety philosophy, quality assurance, and engineering integrity and specifies requirements for the safety of small wind turbines (SWTs) including design, installation, maintenance and operation under specified external conditions. It provides the appropriate level of protection against damage from hazards from these systems during their planned lifetime. This standard is concerned with all subsystems of SWTs such as protection mechanisms, internal electrical systems, mechanical systems, support structures, foundations and the electrical interconnection with the load. While this standard is similar to IEC 61400-1, it does simplify and make significant changes in order to be applicable to small wind turbines. The main changes with respect to the previous edition are as follows: - the title has been modified to better reflect the scope; - restructured into a part Design evaluation and a part Type testing to harmonise use with IEC 61400-22 conformity testing and certification; - caution provided regarding the use of simplified equations; - added various annexes (wind conditions, tropical storms, extreme environmental conditions, EMC testing, dynamic behavior, etc.).

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
