This tab is used to specify the sieve data of the test.

 

 

Sample Mass

 

Wet Sample & Pan Mass: This is the mass of the wet sample and the pan before splitting. This mass is also used to calculate the hydroscopic moisture in the Hydrometer tab.

.

Dry Sample & Pan Mass: This is the mass of the oven dried sample and the pan before splitting. This mass is also used to calculate the hydroscopic moisture in the Hydrometer tab.

 

Mass of Pan: This is the mass of the pan.

 

Dry Sample Mass: The calculated mass of the dry sample obtained by subtracting the pan mass from the dry sample and pan mass. This mass is used to calculate the Percentage Passing.

 

Sieve Information

 

Sample Split for Washing: Check this box if the sample was split to do a hydrometer and/or a washed sieve analysis. If checked the Washed Sieve Data tab will be displayed.

 

Sieve Used for Split: If the Sample Split for Washing box is checked this is the sieve that was used for the split. According to the ASTM D-422 standard the #10 sieve is normally used.

 

Hydrometer: Check this box is a hydrometer analysis was part of this test. If checked the Hydrometer tab will be displayed.

 

Units

 

Mass Units: This is used to select the units for mass, normally grams (g).

 

Sieve Data

 

The sieve data consists of the standard sieves up to and including the sieve used for the split. These standard sieves are from a predefined list of sieve sizes. The data for each sieve size consists of the following:

 

Use: Check this box if this sieve was used in the test.

 

Sieve No.: This is the standard sieve number and is automatically filled in by the program.

 

Sieve Size: The size of the sieve corresponding to the sieve number.

 

Mass Retained: This is the individual mass retained by the sieve. Either the mass retained can be entered or the cumulative mass retained can be entered, it is not necessary to enter both.

 

Cumulative Mass Retained: This is the cumulative mass retained by this sieve and the preceding sieves. The cumulative mass retained can be entered or the individual mass retained can be entered, it is not necessary

to enter both.

 

Cumulative % Passing: This is the calculated cumulative percentage of mass that passes this sieve. This percentage is calculated using the Cumulative Weight Retained and Dry Sample Weight.
