14、ntroduction This Japanese Industrial Standard has been prepared based on the second edition of IS0 Guide 31 2000 Reference materials- Gontents of certificates and labels published in 2000 without modifying the technical contents. Portions underlined with dots in this Standard are the matters not sta
15、ted in the origi- nal International Standard. The certificate which accompanies a certified reference material (CRM) should contain all the information which is essential to its use. Without the certificate, the material, however costly its production, is valueless. It follows, therefore, that produ
16、cers of CRMs should pay very careful attention to the preparation of certificates. The IS0 Committee on Reference Materials (ISO/REMCO) published the first edition of IS0 Guide 31 in 1981. During the past sixteen years there has been considerable growth in the number and variety of reference materia
17、ls produced, and in their use. The increasing demand for reli- ability in the results obtained by analytical and metrological techniques, which has arisen especially from growing concern about pollution of the environment, has led to the demand for a widening range of CRMs of increasingly high quali
18、ty for use in validation of measurement methods and as calibrants. The definition of a CRM in JIS Q 0030 (see clause 2) requires all certified property values to be accompanied by an uncertainty at stated level of confidence and for trace- ability to “an accurate realization of the unit in which the
19、 property value is expressed” to be demonstrated. These additional requirements must therefore be met in the Certificate. The Guide to the expression of uncertainty in measurement, published by IS0 (see Bibliography), summarizes more recent international consideration of the subject of un- certainty
20、 in measurement and will require some modification of the definition of a CRM quoted above. Uncertainty should now be expressed as combined (type A + type B) stan- dard uncertainty or as expanded uncertainty (with a coverage factor to be applied to the combined standard uncertainty). The concept of
21、probability or level of confidence is now no longer central. The first edition of this Standard discussed the difference between the information provided on the label, the certificate, and the certification report, and stressed the brief synoptic nature of the certificate. The past sixteen years, ho
22、wever, have seen a general decline in the issuing of certification reports and an increase in the information provided in certificates. This decline in the publication of certification reports is not necessarily to be condemned, provided all the information appropriate to a full certification report
23、 can always be obtained on application to the producers of the CRM. Production of certification reports is expensive and it is clearly unnecessary for one to be supplied to the same user every time a fresh sample from the same batch of material is purchased. At the same time, the information require
24、d from a certificate is usually more than the certified property value. Details concerning the way in which the container should be opened, the minimum sample size that should be taken for a measurement, the stability of the material, the way in which it should be stored, and, in the case of CRMs wh

Information provided on the label or marked on t
33、he material should serve only to identify the CRM and should be confined to the name of the producer, the name of the material, the producers code for the material, the batch number, and relevant health and safety warnings. It is recommended that the certified property value(s) not be included, in o
34、rder to prevent use of the material without the information in the Certificate having been studied. 5 Certificate headings 5.1 General The various categories of information to be considered in the preparation of a certificate are indicated below. An explanation is given under each heading, together
35、with examples where clarification is considered necessary. The headings are intended to cover the required information on the widest possible range of CRMs which may include reference materials certified for physical properties, amount concentrations of chemical species, isotopic composition (expres
36、sed in SI units) 1 and for conventional and biological properties (defined in internationally agreed measurement scales based on internation- ally agreed measurement procedures, if not defineable in terms of the SI). Some informa- tion is considered obligatory and shall always be provided, even thou
37、gh it may not be important in every case, e.q. the stability of a metal alloy or of the isotopic composition of natural compounds will rarely be questioned, but.j;t.-s.onsi_redtob.mandat.orpand shall .always. be- Pr4Yidfib, A summary of the information which it is essential to include in a certifica
38、te is given in order to assist those organizations, e.g. accreditation bodies, which may wish to include some parts of this Standard in their requirements documents. Other details are optional and may be provided if they would enhance the usefulness of the CRM, e.g. the origin of materials prepared
39、from natural sources. The headings are given in a logical order for presentation of the information, which may be summarized as : - the general particulars of the certifying body and the reference material (5.2 to 5 3 , - a description of the material and its intended use (5.6 to 5.10), the certifie
40、d values, - their traceability and the period of validity of the certificate (5.11 to 5.16), - other information (5.17 and 5.18), and a summary of the essential contents of a certifi- cate (clause 6). This Standard, however, is concerned only with the information contained in certifi- cates, and the
41、 order or titles of the headings may be changed to suit the preference of the producer. 5.2 Name and address of the c e m g body The name (usually given in prominent type at the head of the certificate) should be that of the body or organization that accepts responsibility for the information in the
42、 certificate, i.e. the certifying body. The name should always be accompanied by the full postal address, telephone and fax numbers, and, where available, e-mail address.

The occasional prac
44、tice of issuing provisional certifi- cates can lead to confusion, with the existence of more than one certificate for the same batch of material, and is to be discouraged. 5.4 Name of material As far as possible, the name should describe the type of refer- ence material in sufficient detail to disti
45、nguish it from other similar materials. Thus the name of the rock or ore, followed by its locality or a compositional characteristic, gives more individuality to geological materials for example, “ Syenite (Phalaborwa) ” or For trace analysis of pollutants in natural matrices it is impor- tant to st
46、ate the nature of the matrix and, if several similar reference materials are available, the level of contamination, for example, “Aflatoxin M1 in whole milk powder (medium level)” . (It may, however, be advisable to avoid a detailed description on docu- mentation supplied to carriers and customs aut
47、horities where the naming of toxic pollut- ants may introduce unnecessary problems with dispatch). For metallurgical samples, it is appropriate to indicate the concentration of the important elements, for example “6A1-4V titanium alloy” . “Nepheline syenite”. 5.5 Reference material code and batch nu
48、mber Every CRM should have a unique al- phanumeric code by which it is distinguishable from any other CRM issued by the same or any other producer, e.g. BCR CRM 186, LGC 7016, NIST SRM 41. In addition, the batch number should be stated, even when it is the first batch of a particular CRM. This is to avoid confusion which may arise when a user laboratory has material from more than one batch in use at the same time. Some producers incorporate the batch number in the alphanumeric code for the material, for example NIST SRM 41c. 5.6 Description of the CRM T
