ISO 9001 certification is an internationally recognised standard for quality management and certifies compliance with quality standards for products and services.

The abbreviation «ISO» stands for the international organisation for standardisation with the idea of raising the quality management of companies to a higher level. The aim is to fulfill customer requirements with the help of defined quality and specified business processes. With the continuous improvement process, ISO 9001 also provides the basis for optimising existing processes and quality regulations in a targeted manner.

From 5 to 7 March 2024, KELLER underwent a recertification audit, which takes place every three years. The aim of this audit is to extend the validity of the ISO 9001:2015 certificate.

We are very pleased to have passed the recertification and would like to thank all those involved who contributed to achieving this.
