1. I thought, (from what I was taught years ago), that hardness tests were done at 3 different locations on the ball. Not sure if this still holds true or It was just done in that region at the time.

    1. From what I’ve read they take multiple readings from all over the ball. They also make sure that they check the hardness of each color in the ball. Then they add it all together to get an overall reading

  2. Check multiple spots to see if any are below spec and then average out all of the numbers to see what you get

  3. I think they test about 10 different spots on the ball (dont know how they determine the spots or if they are at random) and I also believe they test every color on the ball. Correct me if I am wrong. Sweet video though Chris

  4. I hear ya mate reminds me of when I went in for a physical the dr said I was 152lbs I told him he was so wrong, and after I got home I weighed myself an sent him the picture from my $20 home scale 141lbs.

  5. USBC has the procedures and setup on testing the hardest of bowling ball. They take 10 measures and find the average with a certain aperatus. CtD clarified on there video.

  6. I own a spectre and I love it. I guess I’ll just sit and wait to see what storm does about a replacement!

  7. You’re not following the protocol USBC published on their site. A hand-held durometer isn’t going to produce reliable results because the pressure you apply with your hand isn’t repeatable accurately.

  8. I seen another post that talked about the testing, a hand held device is not an approved method to test- they use one that uses a weighted system to verify accuracy. I have no idea if this is true or not. Also, storm’s email I received today said they ran new tests and all tested balls passed. Again another YouTube video said Storm would have 30 days to appeal. So from what I’ve been seeing so far is, we Spectre owners are dead in the water for a while. Who knows, glad I have other options. Good luck to us all!

  9. Everyone wants to see a video where you do this for the Purple Hammer… as someone who owns both the Spectre and the Purple it’s be interesting to see… hopefully they get a replacement because I really love the Spectre

  10. The minimum hardness is 73d. When usbc did their test sample they indicated that with their sampling the estimation is that %98.6 of spectres would fail the hardness test. Look up the article and I suggest watching the CTD ban video for a better understanding

  11. Ball needs to be tested in a controlled environment (68-78 degrees F, which you did try). Just because the Ball has sat in that environment doesn’t mean the actual Ball is that temp. I believe usbc officials would use a laser temperature gage for that.

    Ball must be tested at several points around the coverstock instead of just one place as this is how the spot check is done. I believe it’s 10 different spots. The spot check must include a test from each color of the ball.

    The average of all of the tests are taken and that is the result.

  12. Correct me if i am wrong, but isn’t USBC procedure to hit the cover with 500 grit surace prior to testing?

  13. Handheld devices do not give an accurate reading which is why neither the USBC or PBA use this method for official testing.

  14. I have tried a durometer on a ball, handheld like yours. If you fiddle around with it a lot, you will probably see that the values fluctuate very easily with the slightest difference in angle and pressure. Proper hardness must be tested on a desktop big durometer with a handle that comes down and presses with the same force and same angle every time.

    Also i think that the 68 you mentioned, is for individual spot reading. They take many readings in different spots (and all colors) and they average it all out and it should be not below 73. So a spot could have 68 but another could have 78.

  15. although there will be some differences in the environment and in the durometer calibration, a reading of 69 would concern me for any ball that has not yet been subjected to any lane oil or any environmental elements, considering the min limit for a new ball is 73 in a lab setting with the right tools and calibration.

    it’s worth noting that each color should be checked independently, and spots should be checked at the pin, equator, and sprue.


  16. Without a fixture and mechanical arm the handheld test is worthless. Ever have your ball checked nationals?
