The work of preparing International Standards is normally carried o

24、ut through ISO technical committees. Each member bodyinterested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO col

25、laborates closelywith the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Sta

26、ndards. Draft International Standardsadopted by the technical committees are ci rculated to the member bodies for voting. Public ation as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements

27、of this document may be the subject of patent rights. ISO shall not be held responsible for identifying an y or all such patent rights. ISO 15194 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 140, In vitro diagnostic medical devices, in collaboration wit

28、h Technical Committee ISO/TC 212,Clinical laboratory testing and in vitro diagnostic test systems, in accordance with the Agreement on technicalcooperation between ISO and CEN (Vienna Agreement).This second edition cancels and replaces the first edition (ISO 15194:2002),which has been technicallyrev

29、ised.BS EN ISO 15194:2009ISO 15194:2009(E) ISO 2009 All rights reservedIntroduction Reference measurement systems are needed to produce useful and reliable measur ement results,whether in science, technology or routine service, so asto be comparable and ultimately metrologically traceable tomeasurem

30、ent standards and/or measurement procedures of the highest metrological level. Substances ordevices that are used to obtain this metrological traceability, through time, distances and different measurement procedures, are reference materials. Certified reference materials are needed at thehigher met

31、rological levels of a calibration hierarchy.A given certified reference m aterial is supported by documentation containing sources of material, descriptions, measurement results, metrological traceability, instructions for use, stability data and storage conditions, as well as health and safety warn

32、ings. This International Standard specifies the qualityrequirements for such materials and the content of their supporting documentation.Reference materials are used for one of three main purposes: a) calibration of quantityvalues indicated by a measuring sys tem or assigned to another reference mat

33、erial; b) validation or control of trueness of measured values in a given labora tory, orin agroup of laboratories;NOTE In ISO terminology “trueness” is related to “bias”, “systematic effect” and “systematic error”, whereas“accuracy” is related both to “trueness” (with its relations) and “precision”

34、, where the latter is related to “standard deviation”,“coefficient of variation ”, “random effect” and “random error”.c) evaluation of the performance of a new measurement procedure. The maximum acceptable measurement uncertaintyof the assigned value ofa reference material depends onthe requirements

35、 of the measured quantity values obtained by a measurement procedure involving the reference material. As the proper use of a reference material depends on its description, it is important to apply rul es for the documentation of reference materials.The advantages of having standards available are l

37、n Requirements for certified reference materials and the content of supporting documentation1 Scope This International Standard specifies re quirements for certified referenc e materials and the content of theirsupporting documentation, in order for them to be considered of higher metrological order

38、 in accordance withISO 17511. It isapplicable to certified reference materials classifiable as primary measurement s tandards,secondary measurement standards and international conventional calibrators that function either ascalibrators or trueness control materials. This International Standard also

39、provides requirements on how tocollectdata for value determination and how to present the assigned value and itsmeasurement uncertainty. This International Standard applies to certified reference materials with assigned values of differential orrational quantities.Annex A provides information on nom

40、inal properties and ordinal quantities.This International Standard does not apply to reference material s that are parts of an in vitro diagnosticmeasuring system, although it is possible that many elements are helpful. 2 NormativereferencesThe following referenced documents are indispensable for th
