Vetrne turbine - 22. del: Preskušanje skladnosti in certificiranje (IEC 61400-22:2010)
Ta mednarodni standard določa pravila in postopke za sistem certificiranja za vetrne turbine (WT), ki sestavlja obe vrsti certificiranja in certifikacijo projektov vetrnih turbin, postavljenih na kopnem ali na morju. Ta sistem določa pravila za postopke in upravljanje za izvedbo ocenjevanja skladnosti WT in vetrnih elektrarn, glede na določene standarde in druge tehnične zahteve, povezane z varnostjo, zanesljivostjo, delovanjem, preskušanjem in povezavo z električnimi omrežji. Zagotavlja: - definicije elementov v certifikacijskem procesu vetrne turbine, – postopke za ocenjevanje skladnosti vetrne turbine v certifikacijskem sistemu, – postopke za nadzor skladnosti, – pravila za dokumentacijo, ki jo poda vlagatelj za ocenjevanje skladnosti, in – zahteve za certifikacijske in inšpekcijske organe in preskusne laboratorije. Pravila in postopki niso omejeni na določene velikosti ali vrste WT. Vendar veljajo posebna pravila in postopki za majhne vetrne turbine (SWT). Nekateri elementi certificiranja so obvezni, medtem ko velja posebna določba, da so lahko drugi neobvezni. Dokument opisuje postopke, povezane s preskušanjem skladnosti, načrtovanjem, proizvodnjo in načrti za transport, postavitev, vgradnjo in vzdrževanje za tipsko certificiranje. Postopki obravnavajo ocenjevanje obremenitev in varnosti, preskušanje, merjenje lastnosti in nadzor proizvodnje. Dokument za certifikacijo projekta opisuje postopke, povezane z ocenjevanjem, da so posamezne vetrne turbine in podporni strukturni/temeljni načrti v projektu primerni za uporabo, in povezane s transportom, vgradnjo, prevzemom, delovanjem in vzdrževanjem. Postopki obravnavajo ocenjevanje v skladu z vsemi moduli v tem dokumentu, npr. stanjem lokacije, načrtovanjem z lokacijo nekaterih komponent ter nadzorom proizvodnje, transporta, vgradnje in delovanja. Namen teh pravil in postopkov je zagotoviti splošno osnovo za certifikacijo vetrnih turbin in projektov vetrnih turbin, vključno z osnovo za odobritev organov delovanja (to so certifikacijski organi, inšpekcijski organi in preskusni laboratoriji) in skupno priznavanja certifikatov.

Part 22: Conformity testing and certification
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61400-22 has been prepared by IEC technical committee 88: Wind turbines. This standard cancels and replaces IEC WT 01 (2001): IEC System for Conformity Testing and Certification of Wind Turbines – Rules and Procedures.

INTRODUCTION This International Standard defines rules and procedures for conformity testing and certification of wind turbines with respect to standards and technical requirements for wind turbines and wind farms. It is intended to facilitate mutual recognition (reciprocal acceptance) by participants of test results and certificates issued by other participants for obtaining certification at national level and operates within the scope of the IEC 61400 series of standards and technical specifications for wind turbines. The certification procedures in this standard constitute a complete third party conformity evaluation of a wind turbine type, a major component type or one or more wind turbines at a specific location. In addition to design verification and testing, this standard provides information for the recognition of or assessment for approval of the supplier's quality system, regular surveillance through inspection of the supplier's quality system and quality plans, and audit testing of samples. The standard is amongst others intended to result in significant benefit to the applicant by reducing the number of steps necessary to obtain certification or approval at national level.

WIND TURBINES –
Part 22: Conformity testing and certification
1 Scope This International Standard defines rules and procedures for a certification system for wind turbines (WT) that comprises both type certification and certification of wind turbine projects installed on land or off-shore. This system specifies rules for procedures and management for carrying out conformity evaluation of WT and wind farms, with respect to specific standards and other technical requirements, relating to safety, reliability, performance, testing and interaction with electrical power networks. It provides: – definitions of the elements in a wind turbine certification process; – procedures for conformity evaluation in a wind turbine certification system; – procedures for conformity surveillance; – rules for the documentation that is to be supplied by an applicant for the conformity
evaluation; and – requirements for certification and inspection bodies and testing laboratories. The rules and procedures are not limited to WT of any particular size or type. However, special rules and procedures apply for small wind turbines (SWT). Some elements of certification are mandatory, whilst provision is specifically made for others to be optional. For type certification, the document describes procedures relating to conformity testing, design, manufacture, and the plans for transportation, erection, installation and maintenance. The procedures deal with the assessment of loads and safety, testing, characteristics measurements and surveillance of manufacturing. For project certification, the document describes procedures relating to the assessment that particular wind turbines and support structure/foundation designs in a project are appropriate for the application and relating to transportation, installation, commissioning, operation and maintenance. The procedures deal with assessment in accordance with all modules in this document, e.g. the site conditions, the design of site-specific components and surveillance of manufacturing, transportation, installation and operation. The purpose of the rules and procedures is to provide a common basis for certification of wind turbines and wind turbine projects, including a basis for acceptance of operating bodies (i.e. certification bodies, inspection bodies and testing laboratories) and mutual recognition of certificates. The rules and procedures are intended to be used in conjunction with the appropriate IEC/ISO standards and Guides, see Clause

5.3 Recognition arrangements Operating bodies shall seek to obtain, preferably multilateral, recognition arrangements for the acceptance of each other’s work, e.g. test results or quality system certificates. Such arrangements shall be established with reference to the requirements of this standard. When the operating bodies have been accredited by a common accreditation body or where recognition arrangements exist between the corresponding accreditation bodies, the accreditation forms a sufficient basis for mutual recognition of work under the accreditation.
If a recognition arrangement based on accreditation is not possible, a recognition arrangement between operating bodies should include: – the scope of the agreement; – specification of the parts of the wind turbine certification system with unrestricted acceptance; – identification of the signatories and their legal status; – agreement regarding surveillance of each other’s work; – a procedure for handling complaints and appeals; – definition of the parties’ responsibilities; – details of lines of communication; – undertakings regarding confidentiality and security; and – a procedure for maintenance of a register of certificates, conformity statements and test reports issued by the bodies of the agreement. 5.4 Advisory committee Certification bodies operating type and project certification according to this standard shall seek to establish and participate in a joint advisory committee. The committee should establish by-laws and provide advice to the operating bodies on: – harmonization of requirements for documentation for certification; – mutual recognition; – need for amendments to procedures and requirements; – interpretation of procedures and requirements for documentation for conformity assessment; and – interpretation of technical requirements. The recommendations from meetings of the advisory committee shall be made available to accreditation institutes or other relevant boards. 6 Management of the certification system 6.1 General The certification system shall be managed and operated in accordance with
ISO/IEC Guide 65. For project and prototype certification the system may alternatively be managed and operated in accordance with ISO/IEC 17020, in which case certification system elements on 8.3 or 9.5 shall be managed and operated in accordance with ISO/IEC Guide 65. SIST EN 61400-22:2011

6.2 Agreement on certification A certification body shall upon request be prepared to take on work for certification of wind turbines or wind farm projects according to the rules of this standard. The services of the certification body shall be available to all applicants without undue financial or other conditions.
Prior to starting certification work an agreement between applicant and certification body shall be made. In addition to financial and other usual contract conditions, the agreement shall include: – the scope of the certification; – the identification of collaborating bodies (inspection or testing bodies), their accreditation and their responsibilities; – the set of IEC 61400 standards and other technical requirements to which conformity shall be evaluated; – a description of the scope of documentation to be supplied by the applicant for evaluation, e.g. see Annex A: Design documentation; and – conditions for reporting and investigating incidents. 6.3 Issue of certificates and conformity statements
The certification system covers the issue of certificates and conformity statements. A certificate or conformity statement is based on evaluation of wind turbine documentation and the results of inspection, surveillance or testing, as applicable. The results of evaluation shall be documented in a final report. A certificate or a conformity statement shall be issued on the basis of an assessment of the completeness and correctness of an evaluation report or reports. In the case of outstanding issues of no importance to the primary safety of the certified object, a provisional certificate or conformity statement may be issued for a limited period of validity that permits evaluation and verification of the outstanding issues. A certificate or conformity statement shall identify the scope of evaluation, the wind turbine, the supplier, the design assumptions and the set of normative documents, standards and other technical requirements. Examples, showing a suitable format and the minimum information, are given in Annex B. 6.4 Security of relevant documentation The certification body shall keep a file of all received material that is relevant to the certificate or conformity statement. This file shall be kept in a place with restricted access for at least 5 years plus the design lifetime of the object, for certification after the later date of receipt of the material or expiry of the last certificate issued. Subsequently the material
