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 committee has been non-governmental, in liaison with isO, also take part in the work. iso collaborates closely with the InternationalElectrotechnicalCommission(iEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC 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 member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

The entry of water into soil, the movement of water to plant roots, the flow of water to drains and wells and the evaporation of water from the soil surface are but a few of the obvious situations in which the rate of rate of movement of soil water is of great importance to obtain knowledge about the spreading of pollutants The soil properties that determine the behaviour of soil water flow systems are the hydraulic conductivity and water-retention characteristics. The hydraulic conductivity of soil is a measure of its ability to tra
