11、S -,-,- ISO 5667-17:2000(E) iv ISO 2000 All rights reserved Foreword ISO (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 com- m
12、ittees. 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 liai- son with ISO, also take part in the work. ISO collaborates closely with th
13、e 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 3. Draft International Standards adopted by the technical committees are circulated to the memb
14、er 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 this part of ISO 5667 may be the subject of patent rights. ISO shall not be held responsible for i
15、dentifying any or all such patent rights. International Standard ISO 5667-17 was prepared by Technical Committee ISO/TC 147,Water quality, Subcommit- tee SC 6,Sampling (general methods). ISO 5667 consists of the following parts, under the general titleWater quality Sampling: Part 1: Guidance on the
16、design of sampling programmes Part 2: Guidance on sampling techniques Part 3: Guidance on the preservation and handling of samples Part 4: Guidance on sampling from lakes, natural and man-made Part 5: Guidance on sampling of drinking water and water used for food and beverage processing Part 6: Guid

21、wing water, especially of the siltclay () component and associated carbon, as a transport medium for nutrients (especially phosphorus), trace metals, and certain classes of organic compounds (see A.1). Although analysis of suspended solids has been carried out for many years, there are no standard m
22、ethods for field sampling of suspended solids for water quality purposes. While standard methods exist for sampling of suspended mineral sediment for sedimentological purposes these are often not appropriate for the chemical analysis of sus- pended solids. Because of the lack of standards for sampli
23、ng of suspended solids for water quality purposes and the improbability of achieving complete standardization because of differences in the objectives of water quality pro- grammes and the lack of standard apparatus, this part of ISO 5667 provides guidance to the various sampling pro- cedures, their
24、 biases, and alternatives. This part of ISO 5667 excludes sampling protocols that apply to conventional water sampling. Field and laboratory filtration procedures that are conventionally used to measure the quantity of suspended solids are also excluded. Any reference to these methods is solely for
