ISO 17025 and HLS

ISO 17025 is not required to be consistent with the ISO High Level Structure (HLS), as the standard is not classified by ISO as an ISO Management System Standard (MSS). The scope of an ISO management system standard is to specify requirements (repeatable steps) for a quality management system, whereas ISO 17025 is an ISO standard providing general requirements for the competency of laboratories; prepared by CASCO, the ISO Committee on conformity assessment. Laboratories use the guidelines and incorporate them into their overall management system.

ISO 9001, along with other ISO Management System standards, such as ISO 14001, are applicable to a wide range of businesses. They are therefore required to have a common framework, the ISO High Level Structure (HLS). This facilitates easier integration between systems of different disciplines.
