ISO/IEC 17043 Proficiency Testing Providers (PTP)

ISO/IEC 17043 provides the specific requirements for the development, operation and competent operations of Proficiency Testing Providers (PTP).

From March 2024, assessments will be conducted to the requirements of the revised ISO/IEC 17043:2023 Standard.  You can find key resources and information on the Standard revisions as well as documents to help prepare you for your next assessment.


What is ISO/IEC 17043?

The ISO/IEC 17043 Standard is applicable for all types of PTPs.

Testing and calibration organisations who rely on proficiency testing to gauge their own performance can have confidence in the competence of NATA accredited PTPs

ISO/IEC 17043 accreditation

Accreditation to ISO/IEC 17043 demonstrates an independently proven competence in the planning, development and execution of proficiency testing providers. 

A PTP accredited to ISO/IEC 17043 highlights its compliance to an international standard, facilitates efficiencies through continuous improvement processes, reduces potential costs to the provider and allows for a competitive edge in the market.

PT providers operate by providing participating facilities with items based on experimental observation, including measurement, testing, calibration, examination, sampling and inspection. Facilities analyse the items, preferably as part of their normal routine, and report the results to the PT providers.

They are then provided with a report showing how closely their results agree with the accepted values.

Regular participation in a proficiency-testing:

  • Provides staff with an insight into their laboratory’s performance
  • Benchmarks performance with that of other participant facilities
  • Demonstrates to end users of analytical data, regulatory and accreditation bodies that there is a commitment to measurement quality
