Rule 3, Sec. 1m

Rule Clarification
Issued – 10 June 2008

WBSC – SD – CERTIFIED BATS
A reminder to all National Federations and your coaches, players and umpires that the current WBSC bat certification standard (adopted at the 2005 Congress) is the ASTM high-speed batted ball test (100mph). This pertains to bats allowed for use in WBSC competitions or WBSC-sanctioned tournaments, such as World Championships, Olympic Qualifiers, the Olympics, and others. August 31, 2008 will mark the end of the period during which bats that complied with the previous WBSC bat performance standard (1.20 BPF) shall be permitted to be used in WBSC play.

WBSC – SD ADU Comments
The new approved bats will be identified with ISF 100MPH BBS labelling. A list of currently approved bats (whether from the old 1.20 BPF standard or the current ASTM high-speed batted ball test standard) may be viewed here.

Rule Reference – Rule 7 Sec 1 f Effect and Rule 8 Sec 2 k

There is a possibility of a misunderstanding when reading the aforementioned rules together. Unfortunately it will take a rule change to totally clear up, however we cannot do a rule change this year. Until the rules change, we will have separate rulings under Rule 7 Sec 1 f Effect and Rule 8 Sec 2 k. Exception. Rule 8 Sec 2 k Exception will not apply to the on-deck batter who is covered under Rule 7 Sec 1 f Effect.
