ANNEX V Verification procedure for market surveillance purposes For the purposes of checking conformity with the requirements laid down in Annex II, Member State authorities shall test a single water heater or hot water storage tank. The values declared by the manufacturer shall meet the requirements set out in Annex II. If the measured parameters do not meet the values declared by the manufacturer, in accordance with Article 4(2), within the ranges set out in Table 7, the measurement shall be carried out on three additional water heaters or hot water storage tanks. The arithmetic mean of the measured values of these three water heaters or hot water storage tanks shall meet the requirements laid down in Annex II within the ranges set out in Table 7. Otherwise, the model and all other equivalent water heater models or hot water storage tanks models shall be considered not to comply. The Member States authorities shall provide the test results and other relevant information to the authorities of the other Member States and to the Commission within one month of the decision being taken on the non-compliance of the model. Member State authorities shall use the procedures set out in Annexes III and IV.
