Tournament bat testing

[AndyCouchman]

Hi all
I've been watching the Australia Open on ITTF TV .
Before each match, the umpire takes the players bats from envelopes and places on the table.
Im assuming they have been pre-match tested / checked for legality.
If so, what exactly are the umpires looking for?
Thanks
Andy

It's a real pain when they do this, if you want to practice between matches you have to resubmit your bat for testing again!

Players who use boost will pass the VOC test but may fall foul of the rubber thickness test. Recently a few have had to withdraw from matches because of this.
