New balls 2012?
Geplaatst: 05 aug 2011, 19:50
Op diverse buitenlandse fora word gesproken over de invoering van een nieuwe bal na de olympische spelen in 2012
Leek me leuk om daar hier een topic over op te starten dus als iemand wat weet.
dit is wat ik er van vond tot nu toe.
Finally some concrete details after the ITTF expressed the desire earlier this year to phase out the use of celluloid in the production of table tennis ball.

F - Proposed by the Executive Committee - PASSED
The ITTF Executive Committee and the Equipment Committee shall request from Ball Manufacturers to produce 40mm non-celluloid balls after the 2012 Olympic Games, in preparation for the total ban of celluloid production by national governments around the world, and the Equipment Committee shall adjust the Technical Leaflet in terms of description of the new material and tolerances.
Information regarding the material and playing characteristics is unclear, though PVC was once listed in earlier revision of the propositions that has since been removed. What is currently known is that the ball is made out of one single piece, thus eliminating the seam once and for all. Kudos to DHS and DFish for managing the feat. The new ball will also come with a slight increase in diameter between 40mm and 40.60mm as opposed to 39.50mm and 40.50mm.
22 - Proposed by the Equipment Committee - PASSED
To modify Technical Leaflet T3, The Ball (B.3 Size conformity); only
applying to balls not made of celluloid
The minimum diameter of every ball must be at least 39.50mm 40.00mm and its maximum diameter must not exceed 40.50mm 40.60mm. The sample mean average diameter, i.e. the mean of the average of the maximum and minimum diameters for each ball, must be in the range 39.60-40.40mm 40.00-40.50mm. Values below 39.25mm 39.70mm or above 40.75mm are considered in our calculations as outliers.
Hij schijnt dus harder te worden en zonder naad, er zijn al forumgebruikers die er mee geslagen hebben en die zeggen dat hij anders klinkt, en meer geschikt is voor hardhitters.
Ben benieuwd..

Ben benieuwd hoe ze dat gaan aanpakken, een bal zonder naad is nou niet bepaald makkelijk....
