ISO 19443:2018

Quality management systems — Specific requirements for the application of ISO 9001:2015 by organizations in the supply chain of the nuclear energy sector supplying products and services important to nuclear safety (ITNS). 


ISO creates management system standards that provide requirements to ensure that materials, products, processes and services are fit for their purpose. ISO 9001, first issued in 1987, is internationally recognized as a standard for quality management systems. Over one million organizations in over 170 countries are certified to ISO 9001.

Purpose / Aim

With respect to management systems for the nuclear industry, which produces equipment, systems and services for nuclear operators and for NPP or NR vendors, there is a need for enhanced requirements with respect to ISO 9000 with the main objective of conformity assessment guaranties in coherence with the safety importance / classification.



ISO 19443 applies to organizations supplying ITNS products or services. Application of this standard to organizations performing activities on a licensed nuclear site is subject to prior agreement by the Licensee. All the requirements are generic and are intended to be applicable to any organization, regardless of its type or size, or the products and ISO 19443:2018 services it provides.
