From USBC on Storm issues
The manual states: “It is the manufacturers responsibility to ensure that all USBC approved balls comply with all specifications at time of manufacture.†The manual also states that spot-checking balls will be purchased from distribution.
Manufacturers know balls will be tested out of the box. The manufacturer is solely responsible for the surface finishing process and any influence surface finishing may have on specification measurement.
If a manufacturer believes its finishing process will cause variance in specification measurement, then it’s the manufacturer’s responsibility to account for the variance.
Even if surface finish alone caused a ball to measure out of specification, per the manual, the ball is out of specification and subject to removal.
USBC testing does confirm that removing the surface finish polish by sanding will cause the balls to measure harder. However, even if the manual called for sanding balls for hardness testing, (which it does not) the hardness measurement does not increase enough to bring all samples to within specification.
Sorry.
It’s fine to check for as a spot check at box.
To ban them, you should have to return them to the surface that you approved them at.
It’s in the 11th Frame article, polish doesn’t change the actual hardness of the coverstock, it just causes the reading to be soft, since you’re reading polish, not bowling ball.
It probably hasn’t come up to really define the manual on a fair and proper procedure to follow to ban balls since it hasn’t happened much.
Motiv’s issue wasn’t coverstock related.
The Purples, well I believe those were very very soft. And getting softer.
Some use of common sense would be nice here.
Yes, the rules are the rules. As written. But somehow, I don’t think anyone foresaw the perms-ban one one ball and the exclusion from national tournaments of 6 others (more probably, but they stopped testing) as a thing when writing them.
For all testing to be hidden. No datasets to be provided to the manufacturer. Or public. No recourse but to fight it in court if they want, but face bankruptcy if they dared to upset the USBC any further.
See the threat to permanently ban the 6 if the USBC didn’t get what they wanted, even though Storm was abiding by their “agreementâ€.
