Full Description

This method describes the wet preparation of soil samples, as received from the field, for mechanical analysis and the determination of soil constants.

Method B provides that the field sample shall be kept at a moisture content equal to or greater than the natural moisture content. Samples of such soil should be shipped to the laboratory in sealed containers and not allowed to dry out before testing. If no procedure is specified, Method A shall govern.

This standard was formerly designated as test method T 146.
