25、ents PageBS EN ISO 56673:2018ISO 5667-3:2018(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each mem

26、ber 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 the work. ISO collaborates closely with the International El

27、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different type

28、s of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).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

29、 held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www .iso .org/patents).Any trade name used in this document is infor

30、mation given for the convenience of users and does not constitute an endorsement. For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (

31、WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www .iso .org/iso/foreword .html.This document was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 6, Sampling (general methods).This fifth edition cancels and replaces the fourth edition (ISO

32、5667-3:2012), of which it constitutes a minor revision. The changes compared to the previous edition are as follows: updated references in Table A.1; clarification in the Introduction concerning use of the preservation times and conditions set out in Table A.1.A list of all parts in the ISO 5667 ser

33、ies can be found on the ISO website.iv ISO 2018 All rights reservedBS EN ISO 56673:2018ISO 5667-3:2018(E)IntroductionThis document is intended to be used in conjunction with ISO 5667-1, which deals with the design of sampling programmes and sampling techniques.Where possible this document has been b

34、rought into line with current standards. Where new research or validation results have provided new insights, the latest knowledge has been used.Guidance on validation protocols can be found in ISO 17034.ISO 5667-3 provides in Table A.1 validated preservation times and/or conditions as well as descr

35、iptions of best practice. Table A.1 also refers, for each analyte, to those ISO standards available at the date of publication of this ISO 5667-3. This is however not an exhaustive list. Other methods may be used when they have been validated. However, it is strongly recommended that where a method

36、validation is not available, the preservation times for the analyte as listed in Table A.1 for ISO test methods be followed.The preservation and storage conditions and maximum storage times per analyte as listed in Table A.1 should be regarded as default conditions to be applied in the absence of an

37、y other information.However, if validation of preservation techniques and holding times has been carried out, relative to specific circumstances and matrices, by a laboratory, then, provided that it can produce evidence of this validation where they differ from those set out in Table A.1 of this sta

38、ndard, these validated preservation and storage conditions and maximum storage times are deemed acceptable for use by the validating laboratories.Attention is drawn to the proposed development of a new part in the ISO 5667 series, which further elaborates on ISO 5667-3:2018, Annex C, and which will

39、contain guidelines and the elaboration of the required techniques of how to validate new storage times or preservative methods and details of the techniques described. ISO 2018 All rights reserved vBS EN ISO 56673:2018Water quality Sampling Part 3: Preservation and handling of water samplesNOTICE Th

40、is document and the analytical International Standards listed in Annex A are complementary. Where no analytical International Standard is applicable, the technique(s) described in Tables A.1 to A.3 take(s) normative status.When new or revised analytical standards are developed with storage times or

41、preservative techniques differing from those in Tables A.1 to A.3, then the storage times or preservative techniques should be validated and presented to ISO/TC 147/SC 6/WG 3 for incorporation into the next revision of this document.1 ScopeThis document specifies general requirements for sampling, p

42、reservation, handling, transport and storage of all water samples including those for biological analyses. It is not applicable to water samples intended for microbiological analyses as specified in ISO 19458, ecotoxicological assays, biological assays and passive sampling as specified in the scope

43、of ISO 5667-23.This document is particularly appropriate when spot or composite samples cannot be analysed on site and have to be transported to a laboratory for analysis.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constit
