Introduction
Proficiency testing based on interlaboratory comparisons are widely used for a number of purposes and
their use is increasing internationally. Typical purposes for proficiency testing can include:
— evaluation of the performance of laboratories for specific tests or measurements and monitoring
laboratories' continuing performance;
— identification of problems in laboratories and initiation of actions for improvement which, for
example, may be related to inadequate test or measurement procedures, effectiveness of staff
training and supervision, or calibration of equipment;
— establishment of the effectiveness and comparability of test or measurement methods;
— provision of additional confidence to laboratory customers;
— identification of interlaboratory differences;
— education of participating laboratories based on the outcomes of such comparisons;
— validation of uncertainty claims.
The need for ongoing confidence in laboratory performance is not only essential for laboratories and
their customers but also for other interested parties, such as regulators, laboratory accreditation bodies
and other organizations that specify requirements for laboratories. EN ISO/IEC 17011 requires
accreditation bodies to take account of laboratories' participation and performance in proficiency testing.
The European Accreditation Organization (EA) recommends including such activities and their results
more strongly in the demonstration of competence.
EN ISO/IEC 17043 specifies general requirements on the competence of proficiency testing providers.
Their competence covers the design, the performance and the evaluation of proficiency tests.
EN ISO/IEC 17043 explicitly states that this document can be used as a basis for the specification of
specific technical requirements in specific fields of application.
This document is based on EN ISO/IEC 17043 and is designed such that it can be generally applied in
combination with the most current version of EN ISO/IEC 17043. The structure of this document is
aligned with the general structure of standards elaborated by ISO/CASCO.
NOTE ISO/CASCO has specified the following “Terms of Reference” for the revision of ISO/IEC 17043:2010:
Revise ISO/IEC 17043:2010 to insert new CASCO common elements and to make editorial changes to informational
Annex B. Possibly make minor editorial clarifications in technical requirements to clarify PT for inspection and
sampling. Align with other CASCO standards (e.g., ISO/IEC 17025 and ISO 17034 and related standards, e.g. ISO 13528
and ISO Guide 35). Help solve an outdated structure and requirements for management system, also confusion in
symbols for statistical calculations. Bring harmony in structure and management system requirements for users who
also operate testing and calibration laboratories and/or production of reference materials. Finally, bring consistency
in requirements for 3rd party accreditation bodies.
This document supplements EN ISO/IEC 17043 by providing clarification and additional information for
proficiency testing schemes in the field of emission measurements. However, it will not re-state all the
provisions of EN ISO/IEC 17043 and users are reminded of the need to comply with all the relevant
criteria detailed in EN ISO/IEC 17043.
1 Scope
This document supplements the requirements of EN ISO/IEC 17043 by providing clarification and
additional information for proficiency testing schemes for emission measurements. It gives specific
requirements for:
— competence of proficiency testing providers;
— proficiency testing facility characteristics; and
— design, operation and evaluation of proficiency testing schemes by means of interlaboratory
comparisons.
All these aspects are necessary in order to organize and conduct proficiency testing on emission
measurements.
Requirements on the competence of proficiency testing providers cover personnel, organisation,
equipment and environment.
Requirements on the proficiency testing facility characteristics cover measurement sections,
measurements ports and working area for the participants.
Requirements on the proficiency testing schemes cover:
— design, including planning, preparations, homogeneity and stability of test atmospheres and
statistical design;
— operation, including handling and instruction of participants;
— calculation and use of assigned values; and
— testing results evaluation, including statistical data.
This document supports the application of proficiency testing schemes for checking the performance of
testing laboratories in the context of qualification, accreditation and related quality checks in relation to
the application of standardized measurement methods such as standard reference methods (SRM) or
alternative methods (AM).
This document is applicable in combination with EN ISO/IEC 17043 only.
