The golf ball standards in Appendix III of the Rules of Golf govern weight, size, spherical symmetry (the ball must be round, in other words), initial velocity and overall distance standard.
When looking at the List of Conforming Golf Balls, you'll be struck by just how many golf balls are out there (and how many brands you've never heard of).
The list of conforming balls is good for more than just verifying conformity. It also tells you whether the ball is low, medium or high spin for both drivers and irons; the number of dimples; and the method of construction (2-piece, 3-piece, etc.).
