Overview

This article is a subset of ASTM D6913 Particle-Size Distribution (Gradation) of Soils Using Sieve Analysis and covers those parts that change as a result of adding separations to the testing process. In this case, the article describes the state of these parts when no separations are implemented.

Together, these articles provide information on how the various choices available within the QEST Web App version of this test method provide the required pathways to deal with the variations within the test.

Sieve Portion Mass

Dry Mass Determined By

Selection	Action

Selection	Action
Open Default	The appropriate fields are available to record the oven drying process and, ultimately, calculate the dry mass of the test portion.
Open	The available fields are reduced to those needed to record the wet mass of the test portion and a choice is offered for the method of obtaining the water content of the test portion, see below. Once all the information is available, the dry mass of the test portion is calculated from the wet mass using the water content (w). Open

Portion Water Content Determined By

Selection	Action

Selection	Action
Open Default	An embedded water content test (ASTM D2216) is made available to determine the moisture content.
Open	The fields necessary to import a water content result from an ASTM D2216 test are made available. See Associated Test Results for more details on this process.
