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.
No Little League bat has a bpf of 1.2. As of Jan 2009, a LL bat cannot exceed bpf 1.15.
Is BPF 15 little league bat rating the same as 1.15
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
BPF is the Bat Performance Factor of a bat. During testing, a bat is locked into a stationary position and a baseball is shot towards the barrel at a high velocity. The BPF is how fast the ball goes after it bounces off of the bat. For instance, if the ball goes 10% faster after it comes off the bat, then the BPF is 1.10. Most leagues will not allow a bat with a BPF higher than 1.20 (or 20% higher velocity after it is struck)
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.

No. BBCOR is a certification for a baseball bat to be used on the 90-foot base field. I don't even know what BPF is.
The -8 is a Senior League (big barrel) bat. that category has no governing rules (yet), so no one measures their BPF.

is it illegal to use a bpf 1.15 in the state of babe ruth
it doesn't really matter what you use. the only difference is that in a glove for softball the glove is made smaller because a women's hand is usually smaller than a man's hand. Both bats and gloves are governed by certain rules which apply to both games. First, remember when it comes to rules for equipment there is little to no distinction between fastpitch softball and slowpitch softball. In baseball there are three basic levels of amateur play - youth (Little League, Dixie, Babe Ruth, etc.), senior baseball (ages 13 through 15), and adult (high school and college). For this question we will not discuss t-ball, professional or post college adult recreational leagues. Let's talk about bats first. In youth baseball Little League Inc. is king, and they spend money more on testing equipment and safety than the other youth leagues, so most of the other youth leagues follow Little League, Inc.'s lead. The bat rule in Little League requires, among other things, the bat be no more than 2 1/4" in diameter at the widest point in the barrel. It also stipulates the bat cannot perform better than a 1.15 BPF (Bat Performance Factor). Without getting into what that is, suffice it to say that bats must be sent in by the manufacturers and Little League tests them in a certain way and makes sure they are within the 1.15 BPF. In "big barrel" or travel ball leagues there are little to no bat restrictions. In high school and NCAA play the bat must meet BESR (Ball Exit Speed Ration) standards to prevent the ball coming off the bat any faster than desired by the rules committee. The bat must also be 2 5/8" in diameter in the barrel. Softball has a completely different set of governing bodies which dictate bat rules by a different set of standards. The ASA (Amateur Softball Association) is right now one of the largest softball organizations and their rules govern high school and NCAA softball as well. Why different rules for baseball and softball? Because the balls are completely different. Softball is actually an oxymoron because the ball is much harder than a baseball. It's compression value is greater than a baseball, so it comes off of the bat faster than a baseball. Therefore the 2 games need different rules to keep the games safe. The glove... Although most fastpitch softball gloves are made with smaller finger stalls and wrist openings, they can actually be bigger than a baseball glove by the rules. In the Rules of Baseball no glove on the field can be bigger than 12 1/2" from heel to the top of the forefinger, except the first baseman's and catcher's mitt. In softball the ASA requires no glove be bigger than 14". Some other leagues in softball have no specific glove rule. Regardless of the rules, I have never seen or heard of any umpire ejecting a glove based on size. The pocket is generally deeper in a softball specific glove as well, so using it in baseball one may find that digging the baseball out of the deep pocket is a bit more difficult. When shopping for a softball glove be sure to see if it is made for slowpitch or fastpitch. Slowpitch gloves are made for men and fastpitch gloves are made for girls and women.
CAL RIPKEN BASEBALL DIVISIONThe bat may not exceed 33"in length, and the bat barrel may not exceed 2 ¼" in diameter. Only 2 ¼" barrel non-wood bats marked BPF 1.15 will be allowed. Wood 2 ¼" barrel bats are allowed.
Performance standards on non-wood bats have been tightened as they are governed by the BESR (Ball Exit Speed Ratio) standard. In layman's terms, the speed of the batted balls off metal/non-wood bats is comparable to that of the best major league wood bat.This standard has been adopted by the NCAA and the National Federation of State High School Associations.Bats used at the Little League level are governed by the BPF Standard which dictates that the rebound effect of the batted ball off non-wood bats cannot exceed the rebound effect of the batted ball off a wood bat. These standards (both BESR and BPF) are presented to bat makers which they must follow.Mike May Don't Take My Bat Away (www.dtmba.com) 561-427-0657 (office)
ADP or apparatus dew point is the saturation temperature (Ts) of moist air in contact with a cooling coil. ADP or Ts is related to the coil by pass factor (BPF) by the relation: BPF = (Tc - Ts)/ (To - Ts) -------(1) Where Tc = cooling coil temperature Ts = ADP To = outside air dry bulb temperature Rearranging (1) yields Ts = (Tc - To . BPF)/(1-BPF) -----(2) In an ideal (adiabatic) system BPF =0, and Ts =Tc.
Yes, the British Pacific Fleet (BPF) known to the american command as task force 57 was entirely comprised of british ships but was manned by British, New Zealand, Canadian and Australian. The task of the BPF was to nuetralise japanese airfields and aircraft which with thier armourd flight decks they were well suited to. :D
I am looking for that info also. I looked in the rule book and it does not say much other than barrell diameter (2 1/4" and 2 5/8" jr ansd sr) and length. But it also has to be Little League approved. That is the unknown. I know for non-wood it has to be tested (BESR) and have a BPF less or equal to 1.15.

For the most part the CF3 is a non authorized bat. The CF3 by Demarini is not a BBCOR bat nor does it meet the BPF 1.15 standard that almost all organized baseball organizations demand. That means the -3 drop version of the bat is not approved for high school play and the -5 through -10 versions are not approved for use in Little League, Pony, USSSA or Cal Ripken. Most older bats are like this. Just about anything made prior to 2011 is now illegal to use in most organized leagues. This was due to the extremely high baseball exit speeds when these bats were used. The risk of injury to pitchers was dramatically increased with these bats.
BPF1.15 is a lab test for regulating small-barrel baseball bats used by 7-12 yr.-olds in Little League, Cal Ripken League, etc. The large-barrel youth bats used elsewhere in youth baseball are not regulated by BPF1.15, or by any other bat testing standard. BPF was originally invented to test slow-pitch softball bats in the mid-1990's. BPF1.15 places an upper limit on a bat's springiness ("trampoline effect") as compared to that of a rigid wall, which equals BPF 1.00. Wood bats are virtually inelastic, with values of slightly more than 1.00. Small barrel youth bats are not supposed to exceed 1.15. Validity of BPF1.15: Scientists consider BPF1.15 to be scientifically flawed as a test of a bat's springiness, and virtually useless at accurately predicting ball exit velocity, which is the prime metric of bat performance. BPF1.15 does NOT measure or predict "how fast the ball exits the bat when hit", as some claim. BPF1.15 test results do not correlate reliably with field batted-ball speed according to Dr. James Sherwood, the head of the top baseball research lab in the U.S. (NY Times, 10/18/08) Solid wood bats: Lacking a springy barrel, they generate batted-ball speed by clubbing the ball with their concentration of mass in the barrel (also called end-load, and scientifically described as a "higher MOI"). By contrast: Hollow non-wood bats compensate for less (overall) mass and end-load by gaining from: (a) their springiness, i.e., their barrels squish and rebound like a hand-held trampoline; and, (b) their engineered inertial qualities--their lighter overall weight as well as more evenly distributed weight (more balance, less end-load), which allow batters to swing hollow bats faster. To put a cap on small barrel bat performance, BPF1.15 measures one factor (a), the springiness of hollow bats. BPF1.15 does not, however, take into account the other key factor, (b) the inertial qualities of hollow bats that enable greater swing-speed. BPF1.15 "ignores" swing-speed, and assumes that all types of bats can be swung at the same speed. Further, in terms of predicting the (a) the springiness of small barrel bats under game conditions, BPF is defective. This is especially true for expensive high-end bats, for the following reasons: 1. BPF1.15 is conducted at an unrealistically low combined-ball-vs.-bat collision speed of 60 mph. High-end bats are designed to squish and spring-back optimally at realistic ball/bat collision speeds (for example, 50 mph pitch/50 mph swing = 100 mph) that occur in real games. 2. BPF1.15 is conducted on new bats that are not yet broken-in. Today's high-end bats--double-wall bats and carbon-fiber composite bats--have multiple walls and/or layers that do not propel the ball optimally until they are broken-in. (By contrast, the ASA softball bat test requires bats to be mechanically broken-in prior to testing.) 3. The BPF test protocol does not call for random compliance testing. There is no assurance that the performance of tested bats is representative of the performance of bats that are actually sold and used throughout the year. 4. The BPF1.15 lab test data has never been validated through field trials, which scientists consider to be a pre-requisite for legitimate scientific bat regulations. For the above reasons, the BPF1.15 test does not accurately capture the barrel-springiness of small barrel bats in game conditions. Until 2004, almost all small barrel baseball bats were relatively-inexpensive ($40-$150) single-wall aluminum bats. These are inherently limited in elasticity--bats get springier as wall-thickness is decreased, but thinner walls compromise durability. This limits single-wall bat designers. As a result, few single-wall bats can come close to testing at the BPF1.15 limit. But recently-introduced high-end ($150-$250) multi-wall bats--double-walls, and multi-layered carbon-fiber composite models--are significantly springier, test much closer to the limit, and for the reasons cited above can surpass their tested values for elasticity when used in real game conditions. To purchase a small barrel youth bat that has maximum springiness--and that very possibly will perform beyond the maximum allowable springiness--consumers should spring for an expensive double-wall or carbon-fiber composite bat. To summarize: BPF1.15 does NOT measure exit velocity in the lab, does not reliably predict field exit velocity, does not account for swing-speed, and is imperfect at measuring and predicting a major contributor to exit velocity: the trampoline effect of modern hollow youth small barrel bats being used in game conditions. However, in the absence of BPF1.15, it it probable that many multi-wall small-barrel bats would perform even better than they currently perform. By comparison, youth large barrel bats are not subject to any performance regulations.
the answer i think is yes, it may be a bit laggy depending on your area but my friend has a gmod server that he got for free by forwarding his ports, and if you dont have a router then you dont need to do anything apart from click "create multiplayer" i hope you find that answers your question you can add me to your steam friends if u like my name is ^[BPF]ISPYUDIE[BMA]^
The bpsk receiver requires a particular band of frequencies to be passed to generate the required carrier which is further divided and then given to the demodulator. So the basic use of the bpf is to bandlimit the signal generated by the square law device and attenuate any dc levels otherwise. Lpf would simply allow all low frequencies to pass, which is not desired.
