    23、SO (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 member body interested in a subject for which a technical c

    24、ommittee 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 Electrotechnical Commission (IEC) on all matters of electr

    25、otechnical 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 Standards. Draft International Standards adopted by the technical committees are circulated to the m

    26、ember 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 document may be the subject of patent rights. ISO shall not be held responsible for identi

    27、fying any or all such patent rights. ISO 5667-1 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 6, Sampling (general methods), and by Technical Committee CEN/TC 230, Water analysis, in collaboration. Within ISO, this second edition cancels and replaces the first editio

    28、n of ISO 5667-1:1980, ISO 5667-1:1980/Cor.1:1996 and the second edition of ISO 5667-2:1991, which have been technically revised. Within CEN, this document supersedes EN 25667-1:1993 and EN 25667-2:1993. ISO 5667 consists of the following parts, under the general title Water quality Sampling: Part 1:

    35、n of sampling programmes and sampling techniques for all aspects of sampling of water (including waste waters, sludges, effluents and bottom deposits). It does not include detailed instructions for specific sampling situations, which are covered in the various other parts of ISO 5667. Also, it does

    36、not include microbiological sampling, which is covered in ISO 19458 23. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced

    37、 document (including any amendments) applies.

    40、 safety precautions The enormously wide range of conditions encountered in sampling water bodies and bottom deposits can subject sampling personnel to a variety of safety and health risks. Precautions should be taken to avoid inhalation of toxic gases and ingestion of toxic materials through the nos

    41、e, mouth and skin. Personnel responsible for the design of sampling programmes and for carrying out sampling operations should ensure that sampling personnel are informed of the necessary precautions to be taken in sampling operations. Attention is drawn to the requirements of national and/or region

    42、al health and safety regulations. NOTE Precautions against accidents might need to be taken. More specific situations are discussed in 5.3. Weather conditions should be taken into account in order to ensure the safety of personnel and equipment and it is essential that life jackets and lifelines sho

    43、uld be worn when sampling large masses of water. Before sampling from ice-covered waters, the location and extent of weak ice should be carefully checked. If self-contained underwater breathing apparatus or other diving equipment is used, it should always be checked and maintained in accordance with

    44、 relevant ISO or national standards to ensure reliability. Boats or platforms used for sampling purposes should be capable of being maintained in a stable condition. In all waters, precautions should be taken in relation to commercial ships and fishing vessels; for example, the correct signal flags

    45、should be flown to indicate the nature of the work being undertaken. Sampling from unsafe sites, such as unstable river banks, should be avoided wherever possible. If this is not possible, the operation should be conducted by a team using appropriate precautions rather than by a single operator. Whe

    46、rever possible, sampling from bridges should be used as a substitute for bank sampling unless bank conditions are the specific subject of the sampling study. Safe access to sampling sites in all weather is essential for frequent routine sampling. Where relevant, precautions should be taken where add

    47、itional natural hazards are present, such as fauna or flora, that can endanger the health or safety of personnel. Hazardous materials (e.g. bottles containing concentrated acids) should be properly labelled. If instruments or other items of equipment are to be installed on a river bank for sampling

    48、purposes, locations that are susceptible to flooding or vandalism should be avoided or appropriate precautions taken. Many other situations arise during the sampling of water when special precautions should be taken to avoid accidents. For example, some industrial effluents can be corrosive or can c

    49、ontain toxic or flammable materials. The potential dangers associated with contact with sewage should also not be overlooked; these can be gaseous, microbiological, virological or zoological, such as from amoebae or helminthes. Gas protection equipment, breathing apparatus, resuscitation apparatus and other safety equipment should be available when sampling personnel need to enter sampling locations containing hazardous atmospheres. In addition, the concentration of oxygen and of any
