CLEANING means the removal of fluor waxes from not just skis, also from waxing equipment including irons, brushes, scrapers, profiles and even your ski bag.

test text

Ski Base: Check the effective of your wax remover, it must not contain fluor.

Hard Brushes including Roto Brushes: Clean using high air pressure, vacuum it, soak or spray the brushes in a wax remover, then blowing with air pressure and vacuum it when dry.

Soft brushes, corks, fleece, wool, including Roto: (used for powders and liquids) seem to be more difficult to be cleaned, cleaning of those has been non conclusive: best to replace them.

Wax tables, ski profiles, plexi-scrapers: Remove old wax, clean and wiped with wax remover.

Wax iron: Polish using Fibertex, Clean by melting Fluor free hot wax on the iron, then clean using paper.

Skis: First, clean your skis minimum 2 times by liquid wax remover, brushed using a metal brush in between, and let dry.
Second, clean your skis minimum 2 times by hot waxing then scraping off the wax. Pay attention to the fact you must use Fluor Free wax use and clean tools (brushes & scrapers).
Continue to wax your skis with Fluor Free wax when you are going to train on snow, make sure that all your skis are skied on.

Grinding or Regrinding: As a method to clean the base from fluor wax it is not 100% effective. After regrinding it is still recommended to hot wax the base several times with Fluor Free wax.

Ski Bag: Clean with care your ski bag by vacuuming it, blow it by compressed air and wipe inside with wax remover. If its not possible, or you are not sure about final effect then better to replace it!

Ski Straps, Ski band, Working clothes: Wash or replace them

Ski Stand/ Ski holder: Clean with care by vacuum, blow it and wipe with wax remover.

Wax boxes/drawers: Clean with care all boxes and drawers by vacuum, Blow it with compressed air and wipe with wax remover.


Fluor test procedure for IBU Events (World Cup, IBU Cup, WCH, OECH, OWG)

Implementation of the full Fluor ban: 
The International Biathlon Union (IBU) decided to implement a full ban of ski preparation products containing fluorocarbons at all its event series from the 2023/2024 season onwards. For the IBU WC, WCH, IBU Cup, OECCH and OWG the fluor ban is implemented by testing all the skis for the use of banned products. It is the responsibility of competitors and team staff to participate at an IBU event only with material in compliance with the pertinent IBU rules (ECR 1.5.2).

Testing procedure before Start

Procedure – Main change !!!

  • 45-30 min before the individual Start time
  • skis must be delivered to the test station by Athlete, Technician or Team Member
  • We will care for the skis from that moment until 2 min before the start when the Athlete collects the skis


  • 60 min before the Start – Opening of SKI/FLUOR Test Station
  • 45 min before the Start – Test Station Open beginning of the Test Operators and devices ready for control before start
  • 30 min before the Start –latest time for delivering the ski before the dedicated Start time (individual Athlete start time)

SKI Marking

  • Skis need to be delivered, marked by a sticker with the bib number of the athlete
  • Stickers will be handed out before the race in a separate envelope.
  • Technicians are responsible for attaching the appropriate sticker to the skis on a vertical position in the area behind the binding.
  • Ski surface needs to be cleaned from all sides to reduce contamination risk.

Test and results

  • At least one ski from each pair will be tested by FTIR methods to exclude unauthorized material containing fluorocarbons.
  • Ski will be tested in 3 randomly chosen points on the ski base according test procedure.
  • The results of the tests are final and not subject to protest
  • If the ski passes the control successfully, skis will be carefully transported by volunteers in ski holders or directly placed in a dedicated ski stand close to start area, depending on the location of the test station (ECR Skis must be in the “Start” ski stand at least 10 minutes before the start of the respective competitor.
  • If the ski fails the control, the assigned IBU referee for Ski Control will test the ski one more time with a second device to confirm the result. After confirmation of failing the test, information about it, will be provided to the affected team member and TD/RD for appropriate disciplinary action according to the rules. The skis will not be placed in the ski stand or ski holder but marked and returned to the team.

Measuring procedure

  •  0-1 GREEN, move to next point, up to three points
  • 1.01-1.8 YELLOW but remeasure without moving the instrument if <1 GREEN, if >1.81 RED, Green means green point, red means red point.
  • >1.81 RED continues to next point and remeasure in second device by IBU responsible person.

Threshold zones

They are based on the current IBU/FIS calibration model for Alpha II and may change after it is updated. Information about changes will be officially announced before the intended implementation.

Cards system: Card system will be assigned to the Athlete name and NF/Team

  • 1st Red Card – Possibility to change the ski – only one time for each athlete/only once for the 2023/2024 season
  • 2nd Red card: start prohibition according to ECR 11.2.b
  • 1st Yellow Card – official warning for athlete and team
  • 2nd Yellow Card means Red Card


Single Mixed Relay  

In Single Mixed Relay Competitions, Athletes can only use one pair of skis. Rewaxing in between changes is not allowed.


  • Ski Marking- Stickers with start no. (to be delivered together with start bib) – Technicians are responsible for attaching the appropriate sticker to the skis
  • Delivering the skis to the test station and leaving in the ski rack
  • Athlete will take the skis before entering START corridor (around 2 minutes before event start)

Procedure in Test Station:

  • Test Coordinator (from IBU)
  • 4 devices
  • 6 operators , 2 Volunteers receiving skis
  • 2-4 Volunteers for transporting the skis to the Start Area
  • 1 Volunteer in the start area for controlling when the athletes pick up the skis
  • File name: National Code and start no., e.g.: NOR 24, SWE 45, SLO 52…

Test of the ski and ski transport must be conducted in such way that no contamination occurs by the operators, volunteers or OC side.

Ski Test after the race:

All or as many as possible skis will be tested by FTIR methods after each race according to ECR 4.2.3. The skis will be taken by the IBU official and/or the designated volunteers in the finish area and brought to the test station.

  • Careful Ski Transport
  • Cover/ Secure skis in the Start Area
  • Ski pick up time after race test
  • Exclude contamination risk in each step of the procedure
  • Set up Test station places in each IBU event


COMMON WAXING means the same ski preparation for all athletes (already practiced in many NFs).


  • Reduce the difference between Teams (budget, knowledge, competitive, staff,
  • Results according to real indicator (important for NFs’ Teams Coaches)
  • Reduce the participation cost (less wax, cheaper waxes, maybe skis, technicians)
  • More time for Athletes
  • Possible ski test before the race (in similar conditions)
  • Social-Good atmosphere (cooperation between Teams during waxing)


  • Simple Ski preparation – sometimes cannot guarantee the best gliding
  • Complaints about ski gliding will be addressed to the IBU/OCs
  • OCs need to organise an extra place and follow the procedure


Full Ski/Fluor Control

  •  World Cup
  •  World Championship
  •  IBU Cup
  •  Open European Championship
  •  Winter Olympic Games

Common Waxing with random Ski control

  •  Junior Cup
  •  Junior Open European Championship
  •  Youth/Junior World Championship
  •  Youth Olympic Games
  •  Regional cup/event
  •  Education for future



  • Skis must be delivered to the wax station 1 h 15 min before the RACE START
  • Skis will be marked with the Athlete‘s start number

Spot checks:
Randomly chosen skis might be tested by FTIR methods to exclude unauthorized material containing fluor
(one ski from each pair will be tested in 3 randomly chosen points on the ski base according to the IBU
test protocol).
When the skis pass the control successfully, they will be placed back in the ski stand and wait for next
cleaning. If the ski fail at the check, they will not be placed in the ski stand or ski holder but marked and
returned to the team.
It will be possible to replace “fail skis” one time for each Athlete during competition week (or after
appropriate cleaning by team technician).


  • Skis will be brushed by a dedicated brush
  • Cleaned with liquid wax cleaner and wiped with paper


  • Dedicated liquid wax will be applied to skis
  • Skis will wait until the wax dries (according to the producer’s recommendation)


  • Skis will be polished by a dedicated roto brush and wiped


  • Skis will be transported to the Start area by Volunteers in ski holders
  • Skis will be stored in the dedicated Tent close to the Start corridor entrance


  • Skis will be handed over to the Athlete directly before the Start at the entrance to the
    starting corridor

In cooperation with Suppliers, the IBU/OC will provide:

  • Ski Waxes for different conditions
  • Dedicated Roto brushes
  • Liquid wax cleaner
  • Aku drills with an additional battery
  • Ski racks

In cooperation with NFs’ Teams:

  • 6-8 Technicians (every Competition day)
  • 4 Wax tables with double ski profile
  • Experience and cooperation


  • Collect the ski after Official Training
  • More time to prepare skis (possible hot waxing)
  • No stress before the race – just bring skis to the Start area

It is also possible to organize common waxing on the day before the competition. In that
case all skis can be checked by FTIR methods before final common preparation. Liquid wax
application can be replaced by dedicated hot waxing. After polishing all skis need to be
stored in a safe place with limited access. On the race day, skis need to be transported
and placed in a dedicated place close to the start area.


Single Mixed Relay
In Single Mixed Relay Competitions athletes can only use one pair of skis. Rewaxing in
between changes is not allowed.

Ski preparation before Common waxing:

Allowed to be used:

  • Only Fluor Free waxes
  • Manual structure

Not allowed to be used:

  • Any kind of products containing fluorocarbons
