A United States Specialty Sports Association (USSSA) 1.15 Bat Performance Factor (BPF) is a small barrel Baseball bat. The BPF standard is based on the laws of physics.
The "BPF" rating is stamped on the tapered part of the baseball bat, just above handle/grip. The way I understand it, if your bat doesn't have the new USSSA BPF stamp, its not legal to use in most leagues. Check your local league for clarification.
BPF Party was created in 1988.
USSSA Pride was created in 2009.
USSSA stands for United States Specialty Sports Association. Click on the 'USSSA' link on this page to go to their website.

BPF is the Bat Performance Factor. When a bat is tested, it is fixed in a stationery position. A ball is launched at a high speed towards the barrel of the bat. When the ball bounces off of the bat, the speed is recorded to find out how much faster it goes when it comes off of the bat. That is how the BPF is calculated. If the ball comes off of the bat at the same speed, the BPF is 1.00 If the ball comes off of the bat 20% faster, the BPF is 1.20
The -8 is a Senior League (big barrel) bat. that category has no governing rules (yet), so no one measures their BPF.
BPF is bat performance factor or the bounciness of the bat. The higher the number the more bounce a bat has which translates to the ball coming off the bat with more speed and inertia. Sanctioning bodies limit the BPF typically to a 1.20 or less.
