For the purposes of assessing the conformity with the requirements laid down in Articles 3 and 4, Member State authorities shall test a single water heater, hot water storage tank, solar device or package of water heater and solar device and provide the information on the test results to the authorities of the other Member States. If the measured parameters do not meet the values declared by the supplier within the ranges set out in Table 9, the measurement shall be carried out on three additional water heaters, hot water storage tanks, solar devices or packages of water heater and solar device and the information on the test results shall be provided to the authorities of the other Member States and to the Commission within one month of testing. The arithmetic mean of the measured values of these three water heaters, hot water storage tanks, solar devices or packages of water heater and solar device shall meet the values declared by the supplier within the range set out in Table 9.
Otherwise, 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.
