Our company is in accordance with DIN EN ISO 9001 since 2007. Our balls were checked before delivery to the customers according to the relevant quality criteria, such as surface, size, hardness and other criteria. Detailed information regarding the different qualities you can find in the below-mentioned files as well as in our ball selection.

For non-standard specifications we assign particular authorized institutions to accomplish relevant material analysis and tests. We allocate the written test results of these institutions for the customers.
