1 Scope and Field of Application
This standard presents detailed principles to be applied to the design of sampling programmes, to sampling techniques and the handling and preservation of samples of water from natural and man-made lakes.
Sampling for microbiological examination is not included.
This standard is applicable to natural and man-made lakes; the main objectives are specified in 1.1 to 1.3
1.1 Quality characterization measurement
Measurement of water quality over a long period of time for investigating the quality and development tendency of water of natural and man-made lakes.
1.2 Quality control measurement
Measurement of water quality over a long period of time at one or several defined places in a body of water.
1.3 Measurement for specific reasons
Identification and measurement of pollution, for example some species mortality, or other unusual phenomena (water bloom or color).
