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

 

 

Oven Dried Mass

 

Before Wash Sample & Pan Mass: This is the mass of the sample and pan before the wash.

 

After Wash Sample & Pan Mass: This is the mass of the sample and pan after the wash.

 

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

 

Before Wash Sample Mass: This is the calculated mass of the sample before the wash.

 

After Wash Sample Mass: This is the calculated mass of the sample after the wash.

 

Mass after Sieving: This is the calculated mass of the sample from the sieve results. It is calculated from the adding all of the mass retained and is the same as the last cumulative mass retained.

 

% Accuracy: This is the calculated accuracy of the sieving and is obtained by taking the percentage difference between the After Wash Sample Mass and the Mass after Sieving. It should be less than 5%.

 

Hydrometer Accuracy: This is the calculated accuracy of the hydrometer and is obtained using the Before Wash Sample Mass, Corrected Oven Dried Mass, and the Cumulative Percent Passing before the split sieve.

 

Washed Sieve Data

 

The washed sieve data consists of the standard sieves after 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 Before Wash Sample Weight or Corrected Oven Dried Weight (if there is hydrometer data).
