Not entirely correct:
CAT.POL.A.225 Landing — destination and alternate aerodromes
(a) The landing mass of the aeroplane determined in accordance with CAT.POL.A.105(a) shall not exceed the maximum landing mass specified for the altitude and the ambient temperature expected for the estimated time of landing at the destination aerodrome and alternate aerodrome.
For decision heights not less than 200 ft, the maximum landing mass specified in the AFM for the altitude and temperature is determined in accordance with the certification requirements of CS-25.119 (3.2% AEO) and CS-25.121(d). CS-25.121(d) requires a climb gradient of 2.1% OEI for twins at a speed not greater than 1.4 Vsr (typically minimum drag speed).
For decision heights less than 200 ft, the maximum landing mass must additionally comply with the certification requirement of CS-AWO 243.
CS-AWO 243 requires a climb gradient of 2.5% at VREF, typically 1.12 Vsr in the approach climb configuration.
P.S. Like all WAT-limit reqirements, the limiting gradient is a momentary gradient, for the quoted requirements at the pressure and temperature at airport level. That momentary gradient does not define the flight path to another altitude.
