As of July 1, 2020, a ban on fluorine in ski wax will apply to all competition series of the International Ski Federation FIS.
However, as the necessary measuring devices are still under development, the Grand Prix of ski jumpers this summer can be regarded as a transitional phase. An effective control will only be available from the winter of 2020/2021. Then the wax is to be measured contactless on the athletes' skis with specially developed measuring devices - before the start.
If fluorine is detected in an athlete's wax during a check, this will automatically lead to disqualification.
The FIS ban is based on an EU decision that banned certain fluorine compounds from July 1. The International Ski Federation went one step further with its complete ban of all fluorine compounds.
Certain fluorine compounds are suspected of being carcinogenic and are not degradable in nature.
