Standard for Quality Management Systems
ISO 9001 is a voluntary standard for quality management systems, issued by ISO, the International Organization for Standardization.
ISO 9001 has been designed to help organizations ensure that they meet customers' needs and that quality is consistently improved. The quality management system showing the TÜV Rheinland mark is audited and certified by TÜV Rheinland.
Expert auditors analyze and evaluate the customers' organization. If all necessary requirements are fulfilled, the organization is certified according to ISO 9001. The quality management system of the organization is subject to periodic surveillance.
Certified organizations may use the test mark in their communications.
