ANNEX IIISupplementary provisions
ANNEX III Verification procedure When performing the market surveillance checks referred to in Article 3(2) of Directive 2009/125/EC, the authorities of the Member States shall apply the following verification procedure for the requirements set out in Annex I. (1) Member States authorities shall test one single unit per model; (2) The model shall be considered to comply with the applicable requirements set out in Annex I of this Regulation if the values in the technical documentation comply with the requirements set out in Annex I, and if the measured parameters meet the requirements set out in Annex I within the verification tolerances indicated in the Table of this Annex; (3) If the results referred to in point 2 are not achieved, the model shall be considered not to comply with this Regulation. The Member States authorities shall provide all relevant information, including the test results if applicable, to the authorities of the other Member States and the Commission within one month of the decision being taken on the non-compliance of the model. Member States authorities shall use the measurement methods and calculation methods set out in Annex II. Given the weight and size limitations in the transportation of medium and large power transformers, Member States authorities may decide to undertake the verification procedure at the premises of manufacturers, before they are put into service in their final destination. The verification tolerances set out in this Annex relate only to the verification of the measured parameters by Member States authorities and shall not be used by the manufacturer or importer as an allowed tolerance to establish the values in the technical documentation. Table Measured parameter Verification tolerances Load losses The measured value shall not be greater than the declared value by more than 5 %. No load losses The measured value shall not be greater than the declared value by more than 5 %. The electrical power required by the cooling system for no load operation The measured value shall not be greater than the declared value by more than 5 %.
