CERTIFICATES
The BIOVAL BBB are very well tested and have passed an intense quality controle system. They are conform the EU EN13432 standard of degradability and the ISO standard 3290-2001 G3 which is the highest industry standard for precision rolling bearings. Find below a little more explanation on these terms and standards.
The European Standard EU EN13432
Conform to the Bioval certificate of conformity the BBB's are made by subcontractors under Bioval License and heavy quality control measures. The ingredients of the BBB consist of a hardening agent and a biodegradable resin that will degrade in the environment at a speed directly proportional to the local mix of carbon, nitrogen, oxygen and water in the ground. This means the biodegradability highly depends on the local circumstances. These BBB's are the only BB's conforming to European Union standard EN13432!
Pour les normes, l'ISO3290-2001 fait référence à la géométrie de la bille (Norme ISO donc internationale) et la EU EN 13432 a la biodégradation (90% en 6 mois) (Norme EU donc Européenne).
Impossible de trouver la toxicité de celles ci sur le net, seule l'analyse le permet et là je m'en remet à toi.
