From next season, flourvallan is banned.

But time is running out as the nations have not yet seen the test equipment.

The International Biathlon Federation, IBU, and the International Ski Federation, Fis, have indefinitely postponed the September test days, ahead of the upcoming flour-free season.

The reason is that the measurement method is not yet reliable.

- I hope that a decision has not been made far too quickly.

And that there will be fair and clear rules, which are easy to follow, says the biathlon national team's Mona Brorsson.

"Unfortunately it is so"

Sebastian Samuelsson and Mona Brorsson are positive on the core issue.

To ban the unhealthy flour, which since the 90s has made skis slip.

But Samuelsson believes that the test methods must be 100 percent reliable.

- We have seen this not least with doping - that if you have a way of cheating where you think you will get away, then you will do it.

Unfortunately, that is the case, says Samuelsson. 

- There has always been doping, and people have always looked for ways to gain benefits.

I would not be surprised if someone cheated, says Brorsson.

- The test methods must be 100 percent reliable, otherwise it will be a wall cheat.

I am completely convinced of that, says Samuelsson.
