Aug. 28, 2013 HJ Men's 70 481 posts | Technical Questions 1. When a bat is certified are all weights and loads separately tested and certified? 2. Assuming the same batspeed and a ball hit on the sweet spot will a 26 oz maxload hit the ball the same distance as a 30 oz maxload? Theoretically the 30 0z should hit hit farther because of more mass, but if in the certification process permits the 26 to be hotter to meet the standard then perhaps the 26 will generate the same distance. Only Kevin, Alan or Mike can answer this since they understand the the testing process. I have no idea what the answer is? |

Aug. 28, 2013 CallaVett Men's 50 61 posts | Only, one bat needs to be tested for a model to receive its certification. So, the answer is no; not all weights and loads need to be tested. |
Aug. 28, 2013 SSUSA Staff 3466 posts | That is incorrect CallaVett. The Yellow Rip-It bat, one of the very few bats on the not-approved list, failed because some, but not all, weights were non-compliant with the BPF specification. |
Aug. 28, 2013 taits Men's 65 4548 posts | With this in mind, only one bat needs it, it would be interesting to read somewhere which weights were actually presented to be tested and passed the test for certification for all bat companies popular models at least. |
Aug. 29, 2013 Fred S Men's 85 297 posts | I believe each weight is tested. I remember when the PST98Z came out there was no 30 oz as it couldn't pass the ASA test. |
Aug. 29, 2013 CallaVett Men's 50 61 posts | I got my answer directly from the ASA website "ASA Bat Certification Program FAQ". Q: How many bats are tested before a particular model qualifies for the ASA certification mark? A: The standard contract with participating bat manufacturers requires only a single sample bat to be tested at the ASA approved testing facility for certification purposes. Under that contract, the bat manufacturer agrees that every single bat of that model will actually comply with the ASA Bat Performance Standard. |
Aug. 29, 2013 swing for the fences Men's 50 1224 posts | CallaVett, I would think that every size of a particular model bat would be considered a different bat as far as testing.. however, at the end of the day, does it really matter? The Bat Manufacturers have to comply to keep all the sizes of that particular model bat within the requirements as you have pointed out! |
Aug. 29, 2013 CallaVett Men's 50 61 posts | I believe that the bat weight shouldn't have any bearing on determining model for certification; but end-load vs. balanced would change the bat performance by changing the MOI and should be considered for certification. |
Aug. 29, 2013 taits Men's 65 4548 posts | One bat or all weights of that model ... still leaves it open for 'mistakes' to be caught later. Though I doubt they would not like being caught with a mistake have been made like a few have. Last one beings I think was the V73 where the left out a metal cylinder, forget maker & name. Either way it seems to leaves some room for errors between the Bal and El's amongst the different weights. |
Aug. 29, 2013 tattooball 774 posts | It is real simple one bat needs to pass the first test. The moi of the bat is recorded, all of the bats need to have the same moi as the one tested or other weights need to be tested. |
Aug. 30, 2013 CallaVett Men's 50 61 posts | Tatooball, is it the norm for endload and balance to have separate certification tests? I would think the MOI of the bat changes because of weight positioning to achieve the endload or balance feel. |
Aug. 30, 2013 taits Men's 65 4548 posts | This info might interest a few. http://www.acs.psu.edu/drussell/bats/bat-moi.html |
Aug. 30, 2013 tattooball 774 posts | If you have the same bat and balance it the bat will pass. End loads are the hardest to pass and 29 oz is the hardest of all to pass. |
Aug. 30, 2013 taits Men's 65 4548 posts | Point I was going to is that with the different weights, el's or bal, and not all are exact or some even close it, gives a lot off leeway for 'constructive' manufacturing. If your email is same as before when I got the helmet from ya haven't used either, I'm going to sent ya an email on another subject. |
Aug. 30, 2013 HJ Men's 70 481 posts | Tattooball, just started using your ball for league play and thus far well received. Neither tattooball nor anyone else has commented on question 2 above. I can't determine the answer for 2 from comments thus far. It would seem that if a 26 endloaded in a model was as hot as the 30 then the speed off the bat should be the same if the batspeed is the same but I know there is more to it than that. HELP? Mike?? Alan??? |
Aug. 30, 2013 crusher Men's 75 524 posts | HJ (jmo) I have used 26 and 30oz for years. For me a 30oz will send ball farther if swing speeds are the same because I feel my 30oz is traveling faster after the ball strike which means the bat did not absorb very much momentum as it was mostly all transferrd to the ball. The prof for me is the ball is farther away from me with the 30oz. |
Aug. 30, 2013 HJ Men's 70 481 posts | Tatooball, I have been thinking about your post. Are you saying the barrels of the bat in various weights is the same and that as additional weight is added it is done to keep the moi the same or are the barrels in fact different? If the 30 oz barrel is bigger then I think my question may be answered. ????? |
Aug. 30, 2013 taits Men's 65 4548 posts | Tri18, The game playing life is the real test lab. IMO Though I know it (the 'lab') is what it is and needed for it is consistent unless they change or move something. But what surprises me is the one bat any weight or type that passes, 'stamps' them all. Just doesn't seem kosher. (justified) But do see the time factor too. Can't help but wonder haw many don't cut the mustard on the 1st try... |
