## Quality and environment control 

We have an uncompromising approach to quality assurance in every area of our operations and goal of zero failures of our products in the field. Active employee participation in error prevention approaches has enabled us to win the approval of our major customers and to beat their parts per million (ppm) failure rate expectations. The overall objective of our quality management system is to provide all our customers with the assurance that our products and services not only fulfil their current contractual requirements, but will also meet their future needs. 

We are committed to minimising our impact on the environment by developing and promoting environmentally compatible products, and operate in accordance with the ISO 14001 international environmental quality standard. We continuously promote awareness and knowledge of environmental and social responsibility throughout the organisation to ensure that they become a natural part of the decision-making process. As we demand the same standards from our suppliers we only form supply partnerships with those who are accredited to the same international standards. For more detailed information on specific products, please see our website: www.dialog-semiconductor.com.
