Throughout the years, maintaining quality became a standard aspect of the daily work activities. The concept of quality is increasingly important and quality systems are more and more developing into fully-fledged and important company assets. The time when only product quality considered important is far behind us. Companies now also pay much attention to aspects such as; quality of the organization, environment and working conditions. 

Maintaining quality became an important topic within Twin Filter as early as the beginning of the nineties. There were signs from the national and international markets that indicated the necessity to have the organization function on the basis of specified rules and standards. As a supplier we were expected to be able to offer our customers a great extent of certainty that requirements and expectations were matched. Within Twin Filter this quality focus resulted in the implementation of the Twin Filter Quality System, based on the NEN-ISO 9001. At the end of 1997 this system awarded with the desired ISO-certificate.
