Overview
This worksheet allows for data entry per ASTM D1140 using method A or method B.
Embedded Tests
This worksheet uses an embedded test:
The general functionality of embedded tests is described in the article Associated Test Results.
Data Entry
Preparation Section
Procedure
Selection | Action |
|---|---|
A - Non-cohesive soils | Default Sets reported value of Procedure to “A” Sets minimum soaking time to 10 minutes |
B - Cohesive soils | Sets reported value of Procedure to “B” Sets minimum soaking time to 120 minutes |
Nominal Particle Size
Selecting a nominal particle size determines the minimum required test specimen mass from Table 1 of the test method.
This is used, once the Initial Dry Mass of the test specimen is measured, to check that the test method mass requirements are met.
Selecting Nominal Particle Size as N/A indicates that the actual nominal particle size is unknown. In this case the Table 1 check is not carried out.
Measurements Section
Initial Dry Mass
The two methods allowed by the test method for determining the Initial Dry Mass of the test sample are:
Dry the test specimen in an oven and weigh it.
Determine a water content on another sub-sample and calculate the equivalent dry mass from the wet mass of the test specimen.
The worksheet provides this choice by using the following set of radio buttons.
Selection | Action |
|---|---|
Oven Drying | Default Tare and Dry Mass field is available for data entry. Dry Mass calculation is available. The Auxiliary Water Content section is hidden. |
Wet mass and water content | Replaces Tare and Dry Mass field with Tare and Material Wet Mass, Replaces Dry Mass calculation with Material Wet Mass calculation Displays the Auxiliary Water Content section. Displays Initial Material Dry Mass result after Auxiliary Water Content |
Auxiliary Water Content
There are three methods for obtaining the Water Content of the test sample.
Selection | Action |
|---|---|
Measured as part of this test | Default The dry masses in the embedded water contents in the grid will be available for dry mass data entry in the Dry Mass Entry grid. |
Import from another test | Provides for the import of the result of an individual ASTM D2216 test located on the same or a different sample. Results of embedded tests cannot be imported from other worksheets. |
External source (final result only) | Allows the direct entry of a water content result. |
For more information about these options, see Associated Test Results
Mass Check
Once an Initial Dry Mass value is present, a mass check is carried out against the required minimum test specimen mass based on the Nominal Particle Size of the sample.
A test specimen that fails this check will:
still calculate a result
display an error message
enable the Insufficient sample available checkbox
The simplest remedy for this situation is to increase the size of the test specimen until the mass requirement is met.
However, in cases where no further material is available, the test can still be carried out. This exception to the test method requirements needs to be reported by ticking the Insufficient sample available checkbox.
Washing
Soaking Period
Entered as: |  |
|---|---|
Displayed as: |  |
The worksheet will accept soaking period times to the nearest minute and store this value.
Values > 10 minutes are displayed and reported to the nearest 10 minute interval.
To review the entered value, click in the value field.
Washed Portion Dry Mass
This calculation assumes that the same Tare Mass applies here as for the Initial Dry Mass calculation.
The expectation is that, if the Tare Mass is non-zero, the same weighing container is used in both places.
Equipment
For equipment to be available for selection in equipment drop down boxes, the equipment item must first be created in QESTLab's Equipment list. Refer to article Creating Equipment.
The following equipment can be selected on the worksheet:
Equipment label | QESTID | Notes |
|---|---|---|
Balance | 30005 |
|
Oven | 30004 |
|
Guard Sieve | 30137 |
|
Wash Sieve | 30137 |
|
Reporting
The Report checkbox at the end of the Results section allows the selection of optional reportable results.
Tick this checkbox to report that insufficient sample was available to meet the testing requirements.
The results from this worksheet can be reported on the following test reports.

Work Progress and Complete Status
The work progress rules noted below are the default set of rules for this test, these may be overwritten by system administrators and therefore behave differently on each QEST Platform instance.
Progress (%) | Criteria |
|---|---|
0% | The test has been registered in QESTLab. |
50% | The sample initial dry mass has been determined. |
100% | The washing result has been calculated. |
