ANNEX IX
Verification procedure for market surveillance purposes
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.
Member State authorities shall use the procedures set out in Annexes VII and VIII.
