The ISF Playing Rules Commission adopted bat certification standards effective January 1, 2002. Currently, the (ASTM) high-speed batted ball test (100 mph) is used for determining bats allowed to be used in ISF World Championships, World Cups and the Olympic Games. Also included are the qualifying tournaments for both the World Championships and the Olympics.
Bat manufacturers that have certified their bats to-date are: Anderson Bat Company, Combat Softball, DeMarini, Easton, Hillerich & Bradsby (Louisville Slugger), Miken, Mizuno, Nike, Rawlings, Schutt, and Worth.

[NOTE: These bats may have their approval withdrawn if the ISF finds in additional testing that the bat(s) does(do) not meet the bat performance standard.]
