ISO 9001 is an international standard that gives requirements for organization’s quality management system (QMS). It is part of a family of standards published by the International Organization for Standardization (ISO) often referred to collectively as the “ISO 9000 series” or “ISO 9000 family”.

For this reason, you may sometimes hear your suppliers refer to being “ISO 9000 certified”, or having an “ISO 9000-compliant QMS”. This will normally mean that they are claiming to have a QMS meeting the requirement s of ISO 9001, the only standard in the ISO 9000 family that can be used for the purpose of conformity assessment.P[
