Soil quality - Determination of unsaturated hydraulic conductivity and water retention characteristic - Wind's evaporation method

ISO 11275:2004 specifies a laboratory method for the simultaneous determination in soils of the unsaturated hydraulic conductivity and of the soil water-retention characteristic. It is applicable only to measurement of the drying or desorption curve. Application of the method is restricted to soil samples which are, as far as possible, homogeneous. The method is not applicable to soils which shrink in the range of matric head 0 cm to -800 cm. The range of the determination of the conductivity depends on the soil type. It lies between matric heads of approximately -50 cm and -700 cm. The range of the determination of the water-retention characteristic lies between matric heads of approximately 0 cm and -800 cm.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
