ISO 17025 accreditation in Australia: NATA, your scope and international recognition

Why Australian laboratories seek ISO/IEC 17025 accreditation

In Australia the request often arrives as a line in a specification: results from a NATA-accredited laboratory, or from one accredited for the specific test. It can sit in a supply contract, a project specification or a customer's requirements for the data it relies on. Read that line closely. Some specifications name NATA; others accept any accreditation body with recognised status. The wording decides which body you apply to and how you word your scope.

Exporters and laboratories serving overseas groups have a second reason. The Global ACI arrangement, which replaced the ILAC and IAF arrangements on 1 January 2026, exists to help accredited results be accepted internationally, except where regulation or law says otherwise. An Australian calibration certificate or test report carries that weight only when the accreditation behind it is recognised for the tests or calibrations concerned. For the wider case, see the ISO/IEC 17025 benefits guide.

NATA, Global ACI and the application route

NATA accredits testing and calibration laboratories to ISO/IEC 17025 in Australia. It grants accreditation for a defined scope: the tests or calibrations, methods, ranges and sites your laboratory lists and demonstrates. Anything outside that scope is not accredited, even if it is run on the same bench by the same analyst.

NATA publishes its own application steps, and you should work from those. The sequence accreditation bodies generally follow is an application with your documents, a document review, an optional pre-assessment, an on-site assessment by a lead assessor and technical assessors who witness work being performed, the closure of findings by the body's deadline and a decision. The ISO/IEC 17025 accreditation process guide walks through each stage; this page covers only what changes in Australia.

On recognition, NATA's own site describes it as a partner of Global ACI and APAC. The Global ACI list of recognised accreditation bodies, as rendered when we checked it in September 2026, did not show NATA. That may be a limitation of the list rather than a gap in recognition, but a laboratory whose customers are abroad should confirm the position for its scope before relying on it.

Local practice that changes the laboratory project

Choosing the right standard under one body

Because NATA accredits across several standards, Australian groups often run more than one kind of activity under one roof. NATA accredits human pathology laboratories to ISO 15189, not ISO/IEC 17025, and reference material producers and proficiency testing providers to their own standards. A group with a pathology arm, a testing laboratory and a reference material line needs each activity mapped to its standard before the application, so each scope is written once and assessed against the right requirements.

Laboratories that also inspect

Some testing businesses, in construction and engineering for example, issue inspection results beside test reports. ISO/IEC 17020:2026 was published on 27 March 2026. NATA's notice sets a three-year transition ending around March 2029, with assessments to the new edition starting six months after Standards Australia publishes its adoption. Plan the 17020 transition and your ISO/IEC 17025 work together so one set of impartiality and competence records serves both.

An ISO 9001 certificate already on the wall

Many Australian laboratories sit inside businesses certified to ISO 9001 by a JASANZ-accredited certification body. That system can serve as Option B for the management system requirements of ISO/IEC 17025, but NATA will still assess the technical clauses: competence, traceability, method validation, uncertainty and the validity of results. The ISO 9001 vs ISO/IEC 17025 guide sets out what accreditation adds.
