AMO has a new light arrow standard now, in addition to the old 540/60/30 standard.

360 grain arrow, 60 pounds, 30" draw.

None of the manufacturers use it though because it's an ASTM specification and they can't cheat like they do with the IBO 'thing'. I don't know what else to call the IBO speed rating, because it is not, and never has been a standard.
