Normally IBO specs are;

30" draw
70 #
5 grains per pound of pull or in other words a 350 grain arrow shoot with the above specs.

There are a few exceptions in the industry, for example some of the Darton bows are shot at 60# instead of seventy.

AMO Specs:

60 #
9 grains per pound or in other words a 540 grain arrow shot through the bow at the above specs.
