Well, it was the year 2008 that all the pimpled rubbers held in the ITTF depository (to be reserved for 10 years) were taken out and then re-tested in a German engineering lab. Those rubbers with low-friction pimples CoF <0.5 had got excluded from the LARC, 43 items in total.
☛ Shown below is the @UST laboratory testing complex to make friction measurements with a scrupulous accuracy to 0.001 N.

Be happy.
@Knowledge is power, money and mental satisfaction on the topmost.
