Quality standards


Quality within KONI is based on customer requirements, the combination of research, development and modern manufacturing techniques. We’re committed to Total Quality Management and operate within compliance of quality standard ISO 9001, as well as the environmental code ISO 14001 and the health and safety standard OHSAS18001.
All new product developments follow international automotive industry standard IATF 16949, which ensures that all products meet their determined objectives in every way. 
Specifically for our Railway business, we are also International Railways Industry Standard (IRIS) certified.
This allows KONI to lead the way in achieving the balance between damper performance, quality and cost.

Apart form these quality certificates, KONI is in full compliance with the European REACH regulations concerning the production and use of chemical substances, and their potential impacts on both human health and the environment, in both Oud-Beijerland (NL) as well as Ostrava (CZ).

In addition to our quality certificates, KONI has earned many awards and approvals from the Industry for maintaining a high standard of quality control and product specification.

The Quality requirements are transferred to our suppliers through the Supplier Quality Manual, continuously updated to include the most advanced standards and best practices.

Each new damper type will undergo a first article inspection test. During this test our engineers measure the dimensions and the force-speed characteristic of the damper to assure that the damper complies with the specifications. In addition to our first article inspection test, every production damper is performance tested before leaving the factory. Our test machines are connected to a central system, which contain all of the necessary test data for each type of damper. By entering the damper type the test machine knows the exact test data with the applicable tolerance band. All test diagrams are recorded and available upon request.
