Testing Procedures of TT-TCP20 Crown Caps Tumbling Tester
1) Clean and weigh 25 pieces of caps. The weight should be accurate to 0.1mg.
2) Put the caps into the tanks of TT-TCP20 and tumble them for 50 minutes at the speed of 20 rpm per minute.
3) Take the caps out, clean the wearing film on the caps and then weigh the caps. The weight should be accurate to 0.1mg.
4) Do the above steps for a parallel sample. Please take the average of the deviations between values of the two groups as the abrasion values of the caps. Please refer to the following table for qualification range of the results:
Unit Value of Qualification Value of High Quality
- One color mg ≤20 ≤18
- Two colors mg ≤25 ≤22
- Three colors mg ≤35 ≤28
- Four colors mg ≤40 ≤33
