Claussius-Clayperon equation gives accurate result, when the

Volume in the liquid state is negligible compared with that in the vapour state
Vapour obeys the ideal gas law and the latent heat of vaporisation is constant
Vapour pressure is relatively low and the temperature does not vary over wide limits
All of these
