The work of preparing International Standards is norm
14、ally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in t
15、he work. ISO collaborates closely with 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. Draft Guides adopted by the responsible Committee o
16、r Group are circulated to the member bodies for voting. Publication as a Guide requires approval by at least 75 % of the member 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 responsib
17、le for identifying any or all such patent rights. ISO Guide 34 was prepared by the ISO Reference Materials Committee (REMCO). This third edition cancels and replaces the second edition (ISO Guide 34:2000), which has been technically revised. It also incorporates the Technical Corrigendum ISO Guide 3

19、 the transfer of the values of measured or assigned properties between testing and measurement laboratories. Such materials are widely used, e.g. for the calibration of measuring equipment and for the evaluation or validation of measurement procedures. In certain cases, they enable properties to be
20、expressed conveniently in arbitrary units. NOTE The concept “reference material” is included in the concept “measurement standard”, both of which also include physical reference materials used for calibrating instruments in mechanical, non-destructive and construction type-testing facilities. There
21、are an increasing number of reference material producers, and a demonstration of their scientific and technical competence is nowadays a basic requirement for ensuring the quality of reference materials. The demand for new reference materials of higher quality is increasing as a consequence of both
22、the increased precision of measuring equipment and the requirement for more accurate and reliable data in the scientific and technological disciplines. Some previously acceptable reference materials may not meet these more stringent requirements anymore. It is, therefore, not only necessary for refe
23、rence material producers to provide information about their materials in the form of reports, certificates and statements, but also to demonstrate their competence in producing reference materials of appropriate quality. The first edition of ISO Guide 34 set out specific guidelines on the interpreta
24、tion of ISO/IEC Guide 25 and the International Standards prepared by ISO/TC 1761)in the context of reference material production. The more general requirements of these International Standards were omitted. Since the first edition of ISO Guide 34 was published in 1996, the assessment of the competen
25、ce of reference material producers has gained considerable impetus. The second edition of ISO Guide 34 set out all the general requirements in accordance with which a reference material producer has to demonstrate that it operates. The present edition makes these requirements mandatory and in line w
26、ith ISO/IEC 17025:2005/Cor.1:2006 in view of its use for the assessment of the competence of reference material producers applying for accreditation. For tests performed in the medical field, ISO 15189 may be used as the reference instead of ISO/IEC 17025. 1) Including ISO 9000, ISO 9001 and ISO 900

29、demonstrate that it operates, if it is to be recognized as competent to carry out the production of reference materials. 1.2 This Guide is intended for the use by reference material producers in the development and implementation of their management system for quality, administrative and technical o
30、perations. Reference material customers, regulatory authorities and accreditation bodies may also use it in confirming and recognizing the competence of reference material producers. NOTE This Guide is not intended to be used as the basis for conformity assessment by certification bodies. 1.3 This G
31、uide sets out the management system requirements in accordance with which reference materials shall be produced. It is intended to be used as part of a reference material producers general quality assurance (QA) procedures. 1.4 This Guide covers the production of certified and non-certified referenc
32、e materials. For non-certified reference materials, the production requirements are less stringent than for certified reference materials. The minimum requirements for the production of non-certified reference materials are specified throughout the Guide. 2 Normative references The following referen

38、/IEC Guide 99 and the following apply. NOTE The definition of (certified) reference materials in this Guide is referenced to ISO Guide 30 (not ISO/IEC Guide 99). Unless explicitly stated otherwise, the term “certification” is used for the certification of reference materials and shall not be confuse
39、d with product certification or certification of management systems. 3.1 reference material producer body (organization or company, public or private) that is fully responsible for project planning and management, assignment of and decision on property values and relevant uncertainties, authorizatio
40、n of property values and issue of the certificate or other statements for the reference materials it produces 3.2 subcontractor body (organization or company, public or private) that undertakes aspects of the processing, handling, homogeneity and stability assessment, characterization, storage or di
41、stribution of the reference material on behalf of the reference material producer, on a contractual basis, either paid or non-paid (see 5.3.1) NOTE 1 Key tasks/aspects of the reference material production process which cannot be performed by external parties are project planning, assignment and deci
42、sion on property values and relevant uncertainties, authorization of property values and issuing of certificates or other statements for the reference materials. NOTE 2 The concept “subcontractor” is equivalent to the concept “collaborator”. NOTE 3 Advisors, who could be asked for recommendations, b
43、ut who are not involved in decision making or the execution of any aspects mentioned in the definition above, are not considered as subcontractors. 3.3 production of a reference material all necessary activities and tasks leading to a reference material (certified or non-certified) supplied to custo
44、mers NOTE Production of a reference material includes production planning, production control, material handling and storage, material processing (also referred to as “manufacturing” or “preparation”), assessment of homogeneity and stability, issue of statements and post-distribution service of the
45、reference materials. It can include characterization, assignment of property values and their uncertainties, authorization and issue of certificates for certified reference materials. 3.4 reference material RM material, sufficiently homogeneous and stable with respect to one or more specified proper
46、ties, which has been established to be fit for its intended use in a measurement process NOTE 1 RM is a generic term. NOTE 2 Properties can be quantitative or qualitative (e.g. identity of substances or species). NOTE 3 Uses may include the calibration of a measurement system, assessment of a measur
47、ement procedure, assigning values to other materials, and quality control.

NOTE 5 VIM has an analogous definition (ISO/IEC Guide 99:2007, 5.13), but restricts the term “measurement” to apply to quantitative values and not to qualitative properties. Howev
