IEC 61400-22 pdf download.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.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply, together with the relevant definitions contained in ISO/IEC Guide 2 and IEC 60050-415. 3.1 accreditation procedure by which an authoritative body gives formal recognition that a body is impartial and technically competent to carry out specific tasks such as certification, tests, specific types of tests etc. NOTE Accreditation is awarded following successful assessment and is followed by appropriate surveillance. 3.2 applicant entity applying for certification 3.3 certificate holder entity holding a certificate after the certificate is issued NOTE This entity may not be the original applicant but nevertheless is responsible for maintenance of the certificate. 3.4 certification procedure by which a third party gives written assurance that a product, process or service conforms to specified requirements, also known as conformity assessment 3.5 certification body body that conducts certification of conformity 3.6 certification system system that has specific rules for procedure and management to carry out certification of conformity 3.7 commissioning process that encompasses functional safety checks, connecting the wind turbine to the grid and putting it into operation 3.8 conformity statement document issued upon successful completion of evaluation of a certification module The statement includes identification of the receiver, the object, the main normative standards, evaluation and measurement reference reports, validity and certification body. 3.9 evaluation for conformity systematic examination of the extent to which a product, process or service fulfils specified requirements 3.10 final evaluation report report containing the results of conformity evaluations relating to type certification the basis for the decision to issue the type certificate 3.11 inspection systematic examination of the extent to which a product, process or service fulfils specified requirements by means of measuring, observing, testing or gauging the relevant characteristics 3.12 installation process that encompasses site fabrication, assembly and erection 3.13 manufacture process that encompasses fabrication and assembly in a factory or workshop 3.14 manufacturer entity manufacturing the wind turbine or, where relevant, main components of the wind turbine 3.15 modification a new installation or changes to an existing installation, which changes the original design/specification 3.16 operating body body that conducts certification of conformity, testing or inspection
