Belts Certification


General factory certificates are not sufficient for belts used in potentially explosive atmospheres.

If a test report according to ISO 1813 and ISO 9563 is required for the application, it is necessary to inform us of the request for delivery of belts including the certificate when ordering them (when ordering belts via Eshop, please write this request in the "Note" field before by sending the order). The certificate is issued by ContiTech after the test in the production plant.
