Scope: What is ISO 11274 - Soil water retention determination about? ISO 11274 discusses soil quality with a focus on determining its water-retention characteristic. ISO 11274 specifies laboratory methods for the determination of the soil water-retention characteristic. ISO 11274 applies only to measurements of the drying or desorption curve. Four methods are described to cover the complete range of soil water pressures as follows: Method using sand, kaolin, or ceramic suction tables for the determination of matric pressures from 0 kPa to −50 kPa Method using a porous plate and burette apparatus for determination of matric pressures from 0 kPa to −20 kPa Method using a pressurized gas and a pressure plate extractor for determination of matric pressures from −5 kPa to −1 500 kPa Method using a pressurized gas and pressure membrane cells for determination of matric pressures from −33 kPa to −1 500 kPa Guidelines are given to select the most suitable method in a particular case. Who is ISO 11274 - Soil water retention determination for ? ISO 11274 on soil water retention determination is u...
