The equipment that will check that the skis are fluorine-free would actually be available for testing at the end of September, but now the national team has been told that it will be in October.

The season begins on November 27 in Ruka, Finland.

- I'm a little worried that it's a hasty decision.

You want to be 110 percent sure that the control machine works and that you can really ensure that everyone has equal conditions.

Otherwise, I think it's stupid to take it so hastily, says Frida Karlsson.

If the control machine is not completely reliable, the possibility of cheating arises.

SVT Sports expert Anders Blomquist has expressed concern about this.

- If there is no working test device, we will unfortunately see very unfair competitions.

Then it benefits countries that are prepared to cheat to achieve success, he said on Sunday.

Frida Karlsson agrees with the SVT expert.

- If it is possible to get away, there are many who try it.

You have seen that, she says.

In the past, the Finnish federation, among others, has advocated that the ban be postponed by one year, but Sweden has so far trusted the international ski federation Fis.
