# Commission Regulation (EU) No 814/2013 of 2 August 2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for water heaters and hot water storage tanks (Text with EEA relevance), Annex V: Product compliance verification by market surveillance authorities Extent: E+W+S+N.I. The verification tolerances defined in this Annex relate only to the verification of the measured parameters by Great Britain authorities and shall not be used by the manufacturer or importer as an allowed tolerance to establish the values in the technical documentation or in interpreting these values with a view to achieving compliance or to communicate better performance by any means. When verifying the compliance of a product model with the requirements laid down in this Regulation, for the requirements referred to in this Annex the authorities of Great Britain must apply the following procedure— (1)The Great Britain authorities shall verify one single unit of the model. (2)The model shall be considered to comply with the applicable requirements if: (a)the values given in the technical documentation pursuant to paragraph 1(2) of Part 1 of Schedule 1A to the Ecodesign for Energy-Related Products Regulations 2010, and, where applicable, the values used to calculate these values, are not more favourable for the manufacturer or importer than the results of the corresponding measurements carried out pursuant to paragraph 1(2)(b)(vii) of Part 1 of Schedule 1A to those Regulations; and (b)the declared values meet any requirements laid down in this Regulation, and any required product information published by the manufacturer or importer does not contain values that are more favourable for the manufacturer or importer than the declared values; and (c)when the Great Britain authorities test the unit of the model, the determined values (the values of the relevant parameters as measured in testing and the values calculated from these measurements) comply with the respective verification tolerances as given in Table 7. (3)If the results referred to in point 2(a) or (b) are not achieved, the model and all models that have been listed as equivalent water heater models or hot water storage tanks models in the manufacturer's or importer's technical documentation shall be considered not to comply with this Regulation. (4)If the result referred to in point 2(c) is not achieved, the Great Britain authorities shall select three additional units of the same model for testing. As an alternative, the three additional units selected may be of one or more different models that have been listed as equivalent models in the manufacturer's or importer's technical documentation. (5)The model shall be considered to comply with the applicable requirements if, for these three units, the arithmetical mean of the determined values complies with the respective verification tolerances given in Table 7. (6)If the result referred to in point 5 is not achieved, the model and all models that have been listed as equivalent water heater models or hot water storage tanks models in the manufacturer's or importer's technical documentation shall be considered not to comply with this Regulation. (7)... The Great Britain authorities shall use the measurement and calculation methods set out in Annex III and Annex IV. The Great Britain authorities shall only apply the verification tolerances that are set out in Table 7 and shall only use the procedure described in points 1 to 6 for the requirements referred to in this Annex. No other tolerances, such as those set out in designated standards or in any other measurement method, shall be applied.
