It does not say "I know they did not." Now why do I say "Probably Not". I have this opinion because I doubt that the testing protocol requires the summission of a statistically significant number of samples for each type of rubber. I doubt they submitted 30 sample sheets per model number. I doubt they submitted 10 or 5 each.
I would assume that they were only required to submit 1 per model. If the number of samples is low, my point was to ask if sample sheet(s) were representative of the production variation? Did the friction of the sample accurately reflect the friction of production sheets. If it did not, then if subsequent testing of production sheets failed the friction test, a rubber which originally was approved could later end up being banned (or vice versa).
Now your contention that the friction measurement machine may not be accurate or repeatable. This could also be true. Ideally you want a test apparatus to have an accuracy that is 10 times better than the parameter you are measuring.
