Permeability: Material(s) used must have at any point a permeability value of more than 80 l/m2/second. Permeability values are measured on material with a standard multidirectional stretch of 25 %. However, measure on material which cannot be significantly stretched will be effected on unstreched flattened material.
Construction: No zippers or other fastening system is allowed. Seams shall be limited to functional systems and shall not create outside shapes.
External stimulation or influence: Swimsuits which include any system providing external stimulation or influence of any type, including pain reduction, chemical/medical substance release, electro-stimulation etc. are prohibited.
Consistency: Swimsuits effectively manufactured and used shall correspond to and be fully consistent with submitted samples. Any modification before use (including impregnation) is prohibited.
Customisation: There shall be no variation/modification for individual swimmers from the models corresponding to the samples submitted for approval.
The new requirements for swimwear approval will be enforced from January 1, 2010. The list of approved swimsuits by FINA Executive on June 19, 2009 and published on the FINA website, is valid until December 31, 2009.
Approval of swimwear in the future will be done at least 12 months before the next FINA World Championships (50m) or Olympic Games. Moreover, the manufacturers will have the responsibility of making those models available on the market (available on sale to Federations and competitors) at least six months prior to the next coming FINA World Championships or Olympic Games.
As announced by FINA President Dr Julio Maglione, the Bureau appointed a Commission led by Prof. Jan-Anders Manson (from EPFL in Lausanne, SUI) and formed by scientific experts and an athlete's representative to control the swimwear approval process and to monitor the development of the swimsuit industry based on the rules established by the FINA Bureau and the measurable scientific tests on buoyancy and permeability.
