p3 (x1, x2) Fractions p3 (x1, x2) (volume fractions in the individual sieve
classes)
Q3 (x) Cumulative distribution of Q3 (x), volume-related
1-Q3 (x) Cumulative residue distribution of 1-Q3 (x), volume-related
q3 (x) Distribution density q3 (x), volume-related
The following characteristics can be determined with EasySieve:
x (Q3)
x, where Q3 has a given value
Span Span value
U Unevenness, volume-related
Also available in EasySieve Comfort:
Sv
specific surface Sv, volume-related
Sm specific interface Sm, mass-related
Sauter diameter Sauter diameter x
R
St
R
AFS no. AFS Particle Fineness Number (calculable only if the
selected sieves permit the calculation)
RRSB values:
(The RRSB characteristics can be calculated only if the Q3 values of at least 2
sieve fractions are between 5% and 95%)
n
Rise in the RRSB line
d' x value at which Q3(x)=0.632
Correlation Correlation between the RRSB lines and Q3 (x)
The characteristics are explained in more detail in the characteristics section.

When password protection is activated , the program controlled by the input of a
password can be used in measuring mode or in task mode as desired.
In the EasySieve software the measuring mode is intended for the execution of
measurements and for routine evaluations with preset parameters. In the task
mode it is also possible to change all sieving task parameters.
When password protection is activated, EasySieve is in the measuring mode after
start. The task mode is enabled once a password is inputted. The password
protection can be deactivated by the user in the task mode. The program is always
in task mode then.
The following menu items in the main window are in the task mode in addition:
“Options” “Sieving parameters”
“Options” “Edit sieve stack file”
“Sieve analysis” “Save sieving task”
“Extras” “Language”
