Assessment and verification: Testing shall be performed in accordance to EN 14 511:2004. The test shall be performed at the full capacity of the heat pump in question, at the conditions specified in the table. An independent test laboratory accredited for the stated testing shall verify the given values. Heat pumps which are certified in the Eurovent certification programme or DACH certification programme or another programme approved by the competent body do not require additional testing by an independent laboratory for the given values. The test reports shall be submitted with the application.
