The European Rankings are extracts from the ITTF World Rankings. They include all players who have been active in competions and events counting for the World Rankings during the last 8 months. The rankings are updated every month, usually at the end of the first week of the month.
The European Rankings are used for qualification and seeding for ETTU events:

ITTF Europe Top 16
Europe Youth Top 10
