Test conditions No longer current but cited in Building Regulations guidance. The data used in the calculations are based on results from a number of test points derived from capacity and efficiency testing in accordance with ENEN and EN and some additional test point. This test method is replaced by the standard EN For reverse cycle units, the heating capacity and the efficiency class shall be determined from one of the standard rating conditions indicated in Table 5 depending of the heat source: The Amber document status indicator indicates that some caution is needed when using this document – it is either: For reverse cycle air-cooled multisplit units, the heating capacity and the efficiency class shall be determined from the standard rating conditions indicated in Table The testing includes capacity testing, sound power level measurements and to a certain extent safety control tests.
The data used in the calculations are based on results from a number of test points derived from EN Air leakage, thermal insulation and standby power requirement are also tested.
