31、gy or routine service, so as to be comparable and ultimately metrologically traceable to measurement standards and/or measurement procedures of the highest metrological level. Substances or devices that are used to obtain this metrological traceability, through time, distances and different measurem
32、ent procedures, are reference materials. Certified reference materials are needed at the higher metrological levels of a calibration hierarchy. A given certified reference material is supported by documentation containing sources of material, descriptions, measurement results, metrological traceabil
33、ity, instructions for use, stability data and storage conditions, as well as health and safety warnings. This International Standard specifies the quality requirements for such materials and the content of their supporting documentation. Reference materials are used for one of three main purposes: a
34、) calibration of quantity values indicated by a measuring system or assigned to another reference material; b) validation or control of trueness of measured values in a given laboratory, or in a group of laboratories; NOTE In ISO terminology “trueness” is related to “bias”, “systematic effect” and “
35、systematic error”, whereas “accuracy” is related both to “trueness” (with its relations) and “precision”, 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
36、 acceptable measurement uncertainty of the assigned value of a reference material depends on the requirements 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
37、 apply rules for the documentation of reference materials. The advantages of having standards available are listed in ISO/IEC Guide 15. In Clause 3 of this International Standard, concepts are indicated by italicized text. 4 DIN EN ISO 15194:2009-10 EN ISO 15194:2009 (E) 1 Scope This International S
38、tandard specifies requirements for certified reference materials and the content of their supporting documentation, in order for them to be considered of higher metrological order in accordance with ISO 17511. It is applicable to certified reference materials classifiable as primary measurement stan
39、dards, secondary measurement standards and international conventional calibrators that function either as calibrators or trueness control materials. This International Standard also provides requirements on how to collect data for value determination and how to present the assigned value and its mea
40、surement uncertainty. This International Standard applies to certified reference materials with assigned values of differential or rational quantities. Annex A provides information on nominal properties and ordinal quantities. This International Standard does not apply to reference materials that ar
41、e parts of an in vitro diagnostic measuring system, although it is possible that many elements are helpful. 2 Normative references The following referenced documents are indispensable for the application of this document.

47、 standard measurement standard whose quantity value and measurement uncertainty are established using a primary measurement procedure EXAMPLE Primary measurement standard of amount-of-substance concentration prepared by dissolving a known amount of substance of a chemical component to a known volume
48、 of solution. NOTE 1 Adapted from ISO/IEC Guide 99:2007, 5.4. NOTE 2 The concept of “primary measurement standard” is equally valid for base quantities and derived quantities. NOTE 3 Further explanation of the role of primary measurement standards within a calibration hierarchy can be found in ISO 1
49、7511 and ISO 18153. 3.2 secondary measurement standard secondary standard measurement standard whose quantity value and measurement uncertainty are assigned through calibration with respect to a primary measurement standard for a quantity of the same kind NOTE 1 The relation can be obtained directly between the primary measurement standard and the secondary measurement standard, or involve an intermediate measuring system calibrated by the primary standard and assigning a measurement result to the secondary standard.
