Let's see, I believe it goes something like this....The bow being tested should not exceed 60 pounds in draw weight, and the arrow used for the test should weigh 9 grains for every pound of pull. Meaning most arrows are in the neighborhood of 540 grains and are 30 inches long. A chronograph is placed at point blank range to measure the velocity of the arrow.
Honestly, I never knew the exact procedure until you asked that question Art. I didn't want to take the easy way out and look it up on the net, so I called Jennings Archery and talked to a very knowledgeable man there who explained in great detail how the testing was done and then told me the differences between AMO and IBO ratings. Good question.
