# Commission Delegated Regulation (EU) No 812/2013 of 18 February 2013 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to the energy labelling of water heaters, hot water storage tanks and packages of water heater and solar device (Text with EEA relevance), Annex IX: Product compliance verification by market surveillance authorities Extent: E+W+S+N.I. The verification tolerances set out in this Annex relate only to the verification of the measured parameters by Great Britain authorities and shall not be used by the supplier as an allowed tolerance to establish the values in the technical documentation. The values and classes on the label or in the product fiche shall not be more favourable for the supplier than the values reported in the technical documentation. When verifying the compliance of a product model with the requirements laid down in this Delegated Regulation, for the requirements referred to in this Annex, the authorities of the Great Britain shall 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 Article 5(b) of Directive 2010/30/EU (declared values), and, where applicable, the values used to calculate these values, are not more favourable for the supplier than the corresponding values given in the test reports pursuant to point (iii) of the abovementioned Article; and (b)the values published on the label and in the product fiche are not more favourable for the supplier than the declared values, and the indicated energy efficiency class is not more favourable for the supplier than the class determined by 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 9. (3)If the results referred to in points 2(a) or (b) are not achieved, the model and all other equivalent water heater models, hot water storage tanks models, solar device models or package of water heater and solar device models shall be considered not to comply with this Delegated 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 equivalent models. (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 tolerances given in Table 9. (6)If the result referred to in point 5 is not achieved, the model and all other equivalent water heater models, hot water storage tanks models, solar device models or package of water heater and solar device models shall be considered not to comply with this Delegated Regulation. (7)... The Great Britain authorities shall use the measurement and calculation methods set out in Annex VII and Annex VIII. The Great Britain authorities shall only apply the verification tolerances that are set out in Table 9 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.
