Accrediting PT/EQA providers to ISO/IEC 17043

After many years and having several different attempts for the accreditation of proficiency testing provider (PT provider), there is finally one stand-alone standard defining the requirements for the competence of PT providers and therefore an internationally harmonised basis for the accreditation of proficiency test providers. Since February 2010, the ISO/IEC 17043:2010 has replaced ISO/IEC Guide 43:1997 and ILAC G 13:2007. The philosophy of the standard about subcontracting work is different to this of the standards mostly used for accreditation like ISO/IEC 17025:2005 or ISO/IEC 17020:2004, etc. Besides the planning of the proficiency tests (PT), the performance evaluation and the authorisation of the PT reports the ISO/IEC 17043:2010 allows subcontracting for the rest of the work when providing PTs. This is a challenge for the assessors to judge about the competence of a PT provider. In numerous paragraphs, the standard sets very detailed requirements. Nevertheless, there is room for interpretation. For these cases, for example, contracts for subcontractors, procedure for the advisory board, minimum requirements for PT certificates, etc., some proposals are given to enable harmonised approach for the assessment of PT providers.     

ISO/IEC 17043: the new International Standard for proficiency testing

The revision of ISO/IEC Guide 43 is well underway by CASCO Working Group 28, with the author as Convener. The ballot on the committee draft was successfully completed in June 2008. The Working Group met in September to resolve the CD comments and to recommend that the document should advance as an ISO/IEC DIS. The document is in harmony with ISO/IEC 17025 (2005), ILAC G13 (2007), and the IUPAC Harmonized Protocol (2006) for proficiency testing. Major changes from Guide 43 include considerations for inspection bodies, requirements for metrological traceability of assigned values for calibration schemes, limitations on subcontracting, requirements for reporting the uncertainty of assigned values, and for including method information and technical commentary in scheme reports. Minor changes include requirements for equipment used in the manufacture and testing of proficiency test items, considerations for handling laboratories’ reported uncertainties, and the issuance of certificates of participation. These changes have not generated any substantial objections from the CASCO membership and liaisons.     

Experience of implementing of ISO/IEC 17025: conclusions and recommendations of a workshop

The first experiences of implementing of ISO/IEC 17025 have been obtained by the accreditation bodies and laboratories following the standard, and a workshop to discuss the experiences was arranged. This presentation gives the conclusions and recommendations from the workshop based on the lectures and discussions. In general, the adoption of ISO/IEC 17025 has been a smooth process.

Some national characteristics of the implementation of the ISO/IEC 17025 Standard in Russia are considered. The elucidation of some ISO/IEC 17025 Standard prepositions is presented to facilitate implementation of the Standard by accreditation bodies and analytical laboratories claiming accreditation.     

Revision of ISO guide 25

 ISO/IEC guide 25 is the internationally recognised base document for the accreditation of laboratories. Laboratory accreditation is a system of peer assessment and a formal recognition that a laboratory is competent to perform specific tests or types of tests ISO/IEC guide 25 plays a fundamental role in the life of the analytical chemist and is pivotal to the acceptance of the philosophy "once tested everywhere accepted" and to ensuring the mutual acceptance of test data. Within the EU, the attainment of accreditation to ISO/IEC guide 25 has become a way of life and it is now mandatory for laboratories engaged in certain regulatory work areas. Guide 25 is currently under revision and over the past 2 years or so it has been the subject of much debate among the calibration and testing community and it has engendered a considerable amount of written and oral comments. The latest revision entitled "Draft International Standard ISO/IEC DIS 17025: General Requirements for the Competence of Testing and Calibration Laboratories" was circulated to national standard organisations for their "comment and approval" in mid 1998. Voting on this document commenced on 9 July and terminates on 9 December 1998. It is anticipated that a final draft could be circulated in 1999. In accordance with the Vienna agreement this is a parallel ISO/CEN enquiry. This paper will discuss the implications of the technical requirements of the current document for analytical chemistry with particular emphasis on, the strengths, weaknesses and deficits inherent in the draft circulated in July 1998.

ISO compliant laboratory quality systems and incident monitoring improve the implementation of laboratory information systems

Quality systems can provide a means of measuring the rate of occurrence of defined incidents and non-conformities. We have studied the application of laboratory quality systems to monitoring the implementation of laboratory information systems (LIS) in two similar size tertiary hospital pathology laboratories in Australia. At one site, one department implemented a quality system accredited to ISO 9001–1987 and ISO 9001–1994 while the rest of the organisation did not have a formal quality system; this site implemented the Cerner PathNet LIS. At the other site, the organisation was in the process of implementing ISO/IEC Guide 25–1990 and ISO/IEC 17025–1999; this site implemented the PJACC AUSLAB LIS. The rate of quality system incidents and non-conformities was used to track the progress of implementation of the LIS. We found that different quality systems appeared equally useful in monitoring the rate of occurrence of incidents. However, the presence of a formal quality system greatly improved the proportion of incidents that could be investigated and resolved at root cause level. Incident monitoring, as part of a formal quality system, proved to be a useful tool in monitoring and managing the implementation of these LIS. Received: 4 August 2001 Accepted: 21 March 2002

Management review checklist for ISO/IEC 17025 and ISO 15189 quality-management systems

Management reviews are key processes in many quality-management systems, including laboratory-management systems, in accordance with ISO/IEC 17025 and ISO 15189. These reviews are fine opportunities to understand and manage all the inputs and outputs of a quality-management system. Laboratories often meet some difficulties fully exploiting the management-review process because either they do not realize the importance of this process or they do not have the experience to run this process in a way producing the intended results. This work presents a management review checklist which helps laboratories carry out an effective management review going through all the important aspects of the quality-management system.
