Prioritizing implementation of ISO 9001 over ISO 17025 in laboratory

ISO 17025 is the applicable standard for a testing or calibration laboratory to claim technical competency for methods on their scope of work. That said, as ISO 17025 is often a voluntarily adopted standard; if it is not a mandatory requirement for a laboratory, they could start with ISO 9001 implementation and achieve ISO 9001 certification whilst implementing the technical aspects of ISO 17025. Once they are working in accordance with ISO 17025, the laboratory can apply for accreditation, if that is a quality objective.
