CSA N299 is a Canadian standard that outlines Quality assurance (QA) program requirements for the supply of items and services important to nuclear safety. It is part of the CSA (Canadian Standards Association) nuclear series and is often used by suppliers working within Canada’s nuclear industry, including organizations that serve CANDU reactor facilities.
The N299 series ensures that organizations have robust quality management systems in place to consistently deliver products and services that are safe, reliable, and meet regulatory requirements. The series includes several different classifications based on the safety significance of the product or service being supplied.
CSA N299 has four levels, each with increasing rigor depending on how critical the product or service is to nuclear safety:
CSA N299.1 – Highest QA level for items/services that are critical to nuclear safety.
CSA N299.2 – Medium-high QA level for significant items/services.
CSA N299.3 – Moderate QA level for items/services of less safety impact.
CSA N299.4 – Applies to commercial-grade items/services with lower safety significance.
