18、e 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 technical activity. ISO and IEC techn

19、ical 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 (CASCO) is responsible for the de

20、velopment 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 Standard requires approval by at

21、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 prepared by the ISO Committee on

22、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 been technically revised. SANS 1704

Typical p

24、urposes for interlaboratory comparisons include: a) evaluation of 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

25、related to inadequate test or measurement procedures, effectiveness 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

26、 of interlaboratory differences; f) education of participating laboratories 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 mater

27、ials and assessment of their suitability for use in specific test 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 We

28、ights and Measurement (BIPM) and associated regional metrology organizations. 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 laborator

29、y competence is assumed in these applications, but these applications 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 fo

30、r 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. ISO/IEC 17011 requires accreditatio

31、n bodies to take account of laboratories participation and performance 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 tho

32、se evolving areas, especially regarding management, planning and 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 organization

33、s that provide proficiency testing. In doing so it replaces both 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 descriptio

34、ns of typical types of proficiency testing. This International Standard 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 appropri

35、ate statistical methods, selection and use of proficiency testing schemes by laboratories, accreditation bodies, regulatory bodies, and other interested parties.

37、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 as a basis for specific technical require

38、ments 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 the referenced document (including any ame

44、rovider NOTE In some cases, the participant can be an inspection 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 take

45、n in its widest sense and includes, but is not limited 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)

46、sequential scheme where one or more proficiency test items 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

47、 time period; e) single occasion exercise where proficiency 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 wh

48、ere sets of data or other information are furnished and 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

49、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 set or other information used for proficiency testing 3.9 proficiency testing provider organization which takes responsibility for all tasks in the development and operation of a proficiency testing scheme 3.10 proficiency testing roun
