soil sample preparation use of stainless steel

Undisturbed Sampling of Cohesionless Soil for Evaluation ...

10 In practice, samples of cohesionless soils are obtained using drive samplers. These samples are far from undisturbed. Their use is generally limited to laboratory index and classification tests, such as gradation and moisture content that are not sensitive to soil structure.

At the end of the equilibration period, a subsample of the soil is placed in a sample cup and its water potential is determined with the WP4C. If the stainless steel cups are used in the WP4C, this same sample on which water potential was determined can be weighed, oven dried at 105 °C, and reweighed to determine the water content on the sample.
