35 years ago I managed a hardwood lumber business. Back then, the National Hardwood Lumber Assoc. defined rift as 45 - 75 deg off perpendicular to the board's face and quarter-sawn as 75-90 degrees.

I think that the definitions have become somewhat squishy as the assoc. doesn't have the authority it once did.
