2. The List of Authorised Racket Coverings
New authorisations are listed only twice per year. The publication /
printing of the List is normally 1. April, (valid from 1. July) and 1. October
(valid from 1. January). The authorised racket coverings at any time are
those in the valid version of the List, for the specified period. The Internet
version may be corrected for errors during the season. Information will be
given on the ITTF web site. It is not permitted to use racket covering
outside the valid periods given in the List.
It is recommended that new samples for testing should be submitted at
least two months ahead of the publication date...
