20、ctrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of tech
21、nical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of conformity assessment, the ISO Committee on conformity assessment
22、(CASCO) is responsible for the development of International Standards and Guides. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. Draft International Standards are circulated to the national bodies for voting. Publication as an International
23、Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/IEC 17043 was
24、prepared by the ISO Committee on conformity assessment (CASCO). It was circulated for voting to the national bodies of both ISO and IEC, and was approved by both organizations. This first edition of ISO/IEC 17043 cancels and replaces ISO/IEC Guide 43-1:1997 and ISO/IEC Guide 43-2:1997, which have be
25、en technically revised. BS EN ISO/IEC 17043:2010ISO/IEC 17043:2010(E) ISO 2010 All rights reserved vIntroduction Interlaboratory comparisons are widely used for a number of purposes and their use is increasing internationally. Typical purposes for interlaboratory comparisons include: a) evaluation o
26、f the performance of laboratories for specific tests or measurements and monitoring laboratories continuing performance; b) identification of problems in laboratories and initiation of actions for improvement which, for example, may be related to inadequate test or measurement procedures, effectiven
27、ess of staff training and supervision, or calibration of equipment; c) establishment of the effectiveness and comparability of test or measurement methods; d) provision of additional confidence to laboratory customers; e) identification of interlaboratory differences; f) education of participating l
28、aboratories based on the outcomes of such comparisons; g) validation of uncertainty claims; h) evaluation of the performance characteristics of a method often described as collaborative trials; i) assignment of values to reference materials and assessment of their suitability for use in specific tes
29、t or measurement procedures; and j) support for statements of the equivalence of measurements of National Metrology Institutes through “key comparisons” and supplementary comparisons conducted on behalf of the International Bureau of Weights and Measurement (BIPM) and associated regional metrology o
30、rganizations. Proficiency testing involves the use of interlaboratory comparisons for the determination of laboratory performance, as listed in a) to g) above. Proficiency testing does not usually address h), i) and j) because laboratory competence is assumed in these applications, but these applica
31、tions can be used to provide independent demonstrations of laboratory competence. The requirements of this International Standard can be applied to many of the technical planning and operational activities for h), i) and j). The need for ongoing confidence in laboratory performance is not only essen
32、tial 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. ISO/IEC 17011 requires accreditation bodies to take account of laboratories participation and perfo
33、rmance in proficiency testing. There is a growing need for proficiency testing for other conformity assessment activities, such as inspection or product certification. Most of the requirements in this International Standard apply to those evolving areas, especially regarding management, planning and
34、 design, personnel, assuring quality, confidentiality, and other aspects, as appropriate. This International Standard has been prepared to provide a consistent basis for all interested parties to determine the competence of organizations that provide proficiency testing. In doing so it replaces both
35、 parts of ISO/IEC Guide 43:1997. ISO/IEC Guide 43 included not only guidance on development and operation of proficiency testing and selection and use of proficiency testing by laboratory accreditation bodies, but also useful descriptions of typical types of proficiency testing. This International S
36、tandard has preserved and updated the principles for the operation of proficiency testing described in ISO/IEC Guide 43 and has retained in Annexes A to C information on typical types of proficiency testing schemes, guidance on appropriate statistical methods, selection and use of proficiency testin
37、g schemes by laboratories, accreditation bodies, regulatory bodies, and other interested parties.

38、 International Standard specifies general requirements for the competence of providers of proficiency testing schemes and for the development and operation of proficiency testing schemes. These requirements are intended to be general for all types of proficiency testing schemes, and they can be used
39、 as a basis for specific technical requirements for particular fields of application. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of
40、the referenced document (including any amendments) applies.

41、document, the terms and definitions given in ISO/IEC 17000:2004, ISO/IEC Guide 99:2007 and the following apply. 3.1 assigned value value attributed to a particular property of a proficiency test item 3.2 coordinator one or more individuals with responsibility for organizing and managing all of the a
42、ctivities involved in the operation of a proficiency testing scheme 3.3 customer organization or individual for which a proficiency testing scheme is provided through a contractual arrangement 3.4 interlaboratory comparison organization, performance and evaluation of measurements or tests on the sam

44、 from a different population or be the result of an incorrect recording or other gross error. 3.6 participant laboratory, organization or individual that receives proficiency test items and submits results for review by the proficiency testing provider NOTE In some cases, the participant can be an i
45、nspection body. 3.7 proficiency testing evaluation of participant performance against pre-established criteria by means of interlaboratory comparisons NOTE 1 For the purposes of this International Standard, the term “proficiency testing” is taken in its widest sense and includes, but is not limited
46、to: a) quantitative scheme where the objective is to quantify one or more measurands of the proficiency test item; b) qualitative scheme where the objective is to identify or describe one or more characteristics of the proficiency test item; c) sequential scheme where one or more proficiency test it
47、ems are distributed sequentially for testing or measurement and returned to the proficiency testing provider at intervals; d) simultaneous scheme where proficiency test items are distributed for concurrent testing or measurement within a defined time period; e) single occasion exercise where profici
48、ency test items are provided on a single occasion; f) continuous scheme where proficiency test items are provided at regular intervals; g) sampling where samples are taken for subsequent analysis; and h) data transformation and interpretation where sets of data or other information are furnished and
49、 the information is processed to provide an interpretation (or other outcome). NOTE 2 Some providers of proficiency testing in the medical area use the term “External Quality Assessment (EQA)” for their proficiency testing schemes, or for their broader programmes, or both (see Annex A). The requirements of this International Standard cover only those EQA activities that meet the definition of proficiency testing. 3.8 proficiency test item sample, product, artefact, reference material, piece of equipment, measurement standard, data s
