The equipment and devi

40、ces to be used should be checked at random for the presence of emission, absorption and adsorption of substances or influence of properties that are to be determined in the samples to be taken. Examples of 2 ISO 2016 All rights reservedBS ISO 5667-4:2016ISO 5667-4:2016(E)common sampling equipment ar

41、e summarized in Annex A. Advantages and disadvantages of sampling equipment are provided in Annex B. If a boat, marine vessel or any floatation device is used, care shall be taken so that it does not result in contamination of the samples. Additional details regarding sampling from a vessel are summ

42、arized in Annex C. A winch with steel rope and counter is advisable for deeper lakes. This ensures the required sinking and resurfacing velocity of the sampling devices. Any solvents, chemicals or fuels should be stored in sealed non-permeable containers. For example, the use of electric motors on s

43、mall boats can be of value in eliminating the risk of contamination by combustion exhaust and engine lubricants. ISO 5667-14 provides guidance for checking the uptake and emission of the substances to be measured by equipment and devices that are used for sampling.4.2 CleaningA proper quality assura

44、nce and quality control (QA/QC) system should be in place to prevent contamination and detect any contamination that could affect analytical results. All equipment and devices should be regularly mechanically and, if appropriate, chemically cleaned, both internally and externally, to prevent contami

45、nation of water samples.4.3 MaintenanceWhere equipment uses mechanical or other triggering devices, these mechanisms should be regularly tested. Electronic devices and probes should be tested and calibrated according to the manufacturers recommendations. A log of testing and calibration dates and re

46、sults should be maintained.5 Design of the sampling programmeProper sampling is critical to ensure the quality of the investigation and resulting data. Developing a detailed sampling strategy prior to collecting samples will minimize any sampling errors and will provide the most representative sampl

47、e for analysis. General aspects that should be considered in a sampling programme are summarized in ISO 5667-1. These include, but are not limited to, the following:a) purpose of the investigation;b) parameters to be analysed for each sampling point;c) measurements to be carried out at the sampling

48、point as specified in the analytical method, e.g. temperature, dissolved oxygen, pH, turbidity, conductivity;d) frequency and times of sampling and type of sample;e) sampling site and the number and locations of sampling points;f) sampling equipment;g) quality assurance procedures to be followed;h)

49、transport preservation and storage of samples;i) hydrodynamic and morphologic characteristics of the water sampled;j) local circumstances such as water depth, vegetation, accessibility of location and other potential obstacles such as floating layers or sludge layers present;k) sampling depth(s);l) composition and quantity of the water to be sampled;m) safety considerations.
