Organisations can be recognised for their adherence to international standards by achieving accreditation or certification. This involves an external body auditing the systems for compliance against standards.
Laboratory accreditation

Can be achieved by meeting the requirements of ISO Guide 25 or ISO 17025 which review the laboratory’s technical competence. The auditing process is a ‘peer review’ which involves the use of a technical auditor with technical experience in the area to be audited.
