Ich hab den originalen Text gefunden. Der bezieht sich jedoch auf Noppenbeläge und hat den Sinn, dass Noppenbeläge nicht nachbehandelt werden dürfen.

2.4.3.1 Ordinary pimpled rubber is a single layer of non-cellular homogeneous rubber, natural or synthetic, with pimples evenly distributed over its surface at a density of not less than 10 per sq. cm and not more than 30 per sq. cm.
Explanation:
The racket covering should be used as it has been authorised without any physical, chemical or other treatment (except normal wear) – changing or modifying playing properties, friction, outlook, colour, structure, surface, etc.
