The work of preparing International Standards is normally carried out thr
15、ough 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.

16、rates 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. The main task of technical committees is to prepare International Stand
17、ards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication 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 of

26、 ISO 5667-5:2006(E) vi ISO 2006 All rights reserved Introduction ISO 5667 is a group of standards dealing with the general aspects of sampling (Parts 1 to 3) and with the sampling of specific types of water (from Part 4 onwards). ISO 5667-5 covers the sampling of drinking water within a piped distri
27、bution system and should be read in conjunction with ISO 5667-1 and ISO 5667-3. Effective monitoring of drinking water requires collaboration between sampling programme designers, water treatment plant and distribution system operators, sample collectors, laboratory analysts and data users. ISO 5667
28、-5 gives guidance on the selection of sampling locations and the collection of samples when monitoring drinking water from treatment plants and from piped distribution systems. Understanding of the purposes for monitoring drinking water and of the principles behind the methods of analysis is importa
29、nt, since specific sampling protocols can vary widely in accordance with different purposes and different analytical methods. Examples of sampling purposes include: a) checking of drinking water to ensure compliance with national and/or international regulations (e.g. WHO Guidelines for Drinking Wat
30、er Quality 1 and the EU Drinking Water Directive 2); b) determination of the efficiency of a drinking water treatment plant or components thereof (for example, disinfection); c) quality monitoring of the water leaving the treatment plant; d) quality monitoring of the water within the distribution sy
31、stem (including distribution within large buildings); e) search for the cause of contamination of the distribution system (for example, in response to customer complaints); f) monitoring of the corrosive potential of drinking water to plumbing; g) assessment of the effects of materials in contact wi
32、th water on the water quality (chemical and biological); h) monitoring of the influent water and the various processing stages in a food or beverage processing plant, including necessary treatment steps.

34、from treatment works and piped distribution systems 1 Scope This part of ISO 5667 establishes principles to be applied to the techniques of sampling water intended for human consumption. For the purposes of this part of ISO 5667, water intended for human consumption comprises: a) all water either in
35、 its original state or after treatment, intended for drinking, cooking, food preparation, or other domestic purposes, regardless of its origin, plus b) all water used in any production undertaking for the manufacture, processing, preservation or marketing of products or substances intended for human
36、 consumption unless the competent national authorities are satisfied that the quality of the water cannot affect the wholesomeness of the foodstuff in its finished form. The guidance given in this part of ISO 5667 is confined to those circumstances where water is drawn from municipal or similar dist
37、ribution systems (including individual systems) where prior treatment and/or quality assessment has resulted in the water being classified as suitable for drinking or potable process purposes. Specifically, this part of ISO 5667 is applicable to water that is in continuous supply relative to any sta
38、ge of use up to and including the point of consumption in a distribution system. This includes distribution within large buildings in which additional water quality management might be applicable. This part of ISO 5667 is also applicable to sampling situations that can arise relative to the investig
39、ation of system defects or emergency situations where the safety of sampling operatives is not compromised. This part of ISO 5667 does not provide guidance for water sources or for products generated by using drinking water. The followings items are examples of cases not addressed by the present doc
40、ument: the sampling of source water, for example groundwater and surface water impoundments; sampling of drinking water supplies derived from non-continuous sources (for example, from road tankers); sampling of bulk storage of water on airplanes, trains and ships; the sampling of beverage products (
41、including bottled waters) or food containing potable water used in its preparation; sampling of drink vending machines that dispense unsealed cups of drinks.

43、ion drinking water or potable process water 2.2 drinking water all water either in its original state or after treatment, intended for drinking, cooking, food preparation, or other domestic purposes, regardless of its origin 2.3 potable process water all water used in any food-production undertaking
44、 for the manufacture, processing, preservation or marketing of products or substances intended for human consumption. 3 Design of sampling programmes Programmes for the sampling of drinking water, including statistical considerations, should be designed in accordance with ISO 5667-1. Microbiological
45、 investigations of drinking water should be designed and implemented in accordance with ISO 19458. 4 Sampling equipment The general recommendations for sampling equipment given in ISO 5667-1 should be followed and sample containers should be prepared in accordance with ISO 5667-3. On-line sensors/an
46、alysing equipment for water should conform to ISO 15839. Equipment and bottles for sampling for microbiological analysis should conform to ISO 19458. 5 Sample collection locations 5.1 General Sample collection locations should be selected according to the following criteria. a) The chosen collection
47、 locations should yield samples that are representative of the system as a whole, or representative of its main components. b) For each treatment plant, there should be at least one sample collection location on the water intake and at least one sample collection location immediately after the proce
48、ssed water outlet. c) In systems with more than one water source, sample collection locations should reflect the output of each source, the demand on each source and the relative population using each source. d) Sample collection locations should be widely distributed throughout a piped distribution system, the number being proportional to the number of links or branches in the system. e) Sample collection locations should include locations representative of the most unfavo
