# 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), Division 6: Conditions for testing solar devices

Extent: E+W+S+N.I.

The solar collector, solar hot water storage tank and pump in the collector loop (if applicable) shall be tested separately. Where the solar collector and solar hot water storage tank cannot be tested separately, they shall be tested in combination.
The results shall be used for the calculations of Qnonsol for the load profiles M, L, XL and XXL under the average climate conditions set out in Tables 4 and 5 and Qaux .
