When test at bivalent temperature cnditin has been cmpleted, the ther selected part lads shall be tested. b) Test at ther part lad cnditins At each part lad cnditin, measured COP shall nt be lwer than -8% cmpared t the declared COP. If each measured COP is within the tlerance, SCOP is calculated using the declared COP fr each part lad cnditins and declared auxiliary mdes cnsumptin. If the calculated SCOP is nt lwer than -8% cmpared t the declared SCOP, then the test is ver and nr SCOP nr η are rerated. If the calculated SCOP is lwer than -8% cmpared t the declared SCOP, the declared SCOP and η shall be rerated. The rerated SCOP and η shall be equalled t the calculated nes. SCOP and η fr each mdels f the sub-type fr each declared applicatins and each declared climates shall be calculated accrding the declared part lad data and auxiliary mdes cnsumptin. Each SCOP being lwer than the calculated value -8% shall be replaced by the calculated SCOP and η shall be recalculated accrdingly If at least ne f the measured COP is lwer than -8% cmpared t the declared COP then, all the nn-tested EN 14825 part lad cnditins and ne auxiliary mde cnditin (chsen by the certificatin bdy) shall be tested. SCOP is calculated using the declared COP when they are within the 8% tlerance, therwise using the measured COP.

Heating test is passed if nne f the P designh and η fr all tested applicatins have been rerated. 4.2.2.2 Space cling a) Cnditin A test Cnditin A is tested. If heating capacity measured under cnditin A des nt deviate frm P designc frm mre than -8% then the test cntinues. If nt, the test is interrupted. The certificate hlder shall prvide a new cmplete set f declared values t the certificatin bdy and the chsen recgnised labratry within tw weeks f the interrupted test. The tests may then be restarted frm the beginning and the P designc shall be rerated as fllw: Fr the tested mdel: rerated P designc = P dc (35) Equatin 7 Fr the ther mdels f the sub-type, same deviatin in between declared and rerated P designc f the tested mdel shall be applied. When test at A temperature cnditin is cmpleted, the ther selected part lad shall be tested. b) Test at ther part lad cnditins At each part lad cnditins, measured EER shall nt be lwer than -8% cmpared t the declared EER. If every measured EER are within the tlerance, SEER is calculated using the declared EER fr each part lad cnditins and declared auxiliary mdes cnsumptin. If the calculated SEER is nt lwer than -8% cmpared t the declared SEER, then the test is ver and SEER is nt rerated. If the calculated SEER is lwer frm declared SEER by mre than -8%; then SEER shall be rerated and the rerated SEER shall be equal t the calculated SEER. SEER fr every mdel f the sub-type shall be recalculated and rerated if calculated SEER are lwer than -8% cmpared t the declared SEER If at least ne f the measured EER is lwer than -8% cmpared t the declared EER then, every nn-tested EN 14825 part lad cnditins and ne auxiliary mde cnditin (chsen by the certificatin bdy) shall be tested. SEER is then calculated using the declared EER when they are within the 8% tlerance, therwise using the

In case the test is failed and in case several heat surces are declared, all heat surces shall be rerated unless the certificate hlder asks fr a full perfrmance test n the nntested heat surce. If the test cannt fulfil the requirements f EN 16147 in term f water temperature; the certificate hlder shall prvide a new cmplete set f declared values: lad prfile; η DHW and V 40 (nly fr DHW heat pumps) t the certificatin bdy and the chsen recgnised labratry within tw weeks f the interrupted test. The tests may then be restarted frm the beginning. DHW test is passed if fr each declared climate the test has been perfrmed fr the declared lad prfile and if neither η DHW nr V 40 has been rerated, therwise the test is failed. 4.3.1 η DHW If an bserved deviatin between declared and measured η DHW exceeds -8 %, then η dhw shall be rerated. Rerating f tested mdel rerated η DHW = measured η DHW (1 + 0. 08) Equatin 9 Rerating f the ther mdels f the sub-type and f the ther heat surce when relevant
