Impeller Trimming is done upto 70% of full impeller size?

Impeller Trimming is done upto 70% of full impeller size? Is this correct? if no what is limit?
My Question:
In a performance curve, Impeller size given for particular model is 10" to 7.5" inch. My impeller is 7.5" inch at duty point on these performance curve. Is it Technically correct, to trim the impeller for this model with above limit percentage?
