The ISF Playing Rules Commission adopted bat certification standards effective January 1, 2002. Currently, the (ASTM F2219) 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.

August 31, 2008 marked the end of the period during which bats that complied with the previous ISF bat performance standard (1.20 BPF) were permitted to be used in ISF play.

Manufacturers that currently participate in the bat certification program are: Combat Softball, DeMarini, Easton, Hillerich & Bradsby (Louisville Slugger), Miken, Mizuno, and Worth.

The following companies are listed in the drop-down menu below, however, they have dropped out of the program, so their bats will expire five years from the date that is listed (model-by-model) as when it was added as certified: Baden Sports and Rawlings.

Any Albin, Anderson Bat Company, Nike, Rip-It or Schutt bat previously ISF certified has expired, so, no bats from either of those companies are permitted in ISF play.

Click on one of the company names in the drop-down menu below to view a complete list of that manufacturer's models that have been deemed "approved" and meet ISF Bat Certification standards as provided by the ISF Equipment Standards Commission. [NOTE: These bats may have their approval withdrawn if the ISF finds in additional testing that the bat(s) does(do) not meet the bat performance standard.]


Inquiries into bats or any other softball equipment may be addressed to the chairman, ISF Equipment Standards Commission, 1900 So. Park Road, Plant City, Florida 33563 USA.
