原文恕刪...

前一篇原po摘錄好棒網站長的文章，其實已經是好幾年前寫的了...
ISF的球棒驗證方式其實有做修改了...(ASA也有稍微修正)
不過還是可以當作參考...

如果各位有去比較新舊球棒上的ISF標誌就會發現有不一樣...

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.

Bat manufacturers that have certified their bats to-date are: Combat Softball,
DeMarini, Easton, Hillerich & Bradsby (Louisville Slugger), Miken, Mizuno,
Nike, Rawlings, and Worth.
