Softball Canada has adopted the ISF bat certification standards for 2013 and the league will adhere to these as well.
- Any bat that appears on the ISF approved bat list and has an ISF certification stamp will be accepted for play at a Softball Canada event. Some bats may also have the 2000 or 2004 ASA certification mark which would also be acceptable for Fast Pitch.
- The bat must meet the compression standards outlined by the ISF and can be tested to ensure that they are in the proper range.
- The bat must still pass a visual inspection per the current Softball Canada rulebook
In general, if a bat has a clearly visible ASA or ISF stamp, it will be deemed legal for league play in 2013.
