1 Certificate No. This certificate is issued to for the wind turbine wind turbine class (class, standard, year) Vestas Wind Systems A/S Hedeager Aarhus N Denmark Vestas V MW / V MW S (IEC IB)*, :2005 *S (IEC IB) - IEC wind turbine class IB expect for the temperature range. This certificate attests compliance with IEC Series as specified in subsequent pages. It is based on the following reference documents: Design basis evaluation conformity statement Design evaluation conformity statement test conformity statement Manufacturing conformity statement Characteristic Measurements conformity statement Final evaluation report DB-DNVGL-SE (DB-DNV-DSS ) DE-DNVGL-SE (DE-DNV-DSS ) TT-DNVGL-SE (TT-DNV-DSS ) ME-DNVGL-SE (ME-DNV-DSS ) TCM-DNVGL-SE (TCM-DNV-DSS ) FER-TC-DNVGL-SE The conformity evaluation was carried out in accordance with the rules and procedures of the IECRE System The wind turbine type specification begins on page 2 of this certificate. Outstanding issues are listed on page 8 of this certificate. Changes in the system design or the manufacturer s quality system are to be approved by the DNV GL. Without approval, the certificate loses its validity.
