CORRECT ANSWERS 2026
What is the maximum mass that can be retained on a 4. 75mm number 4 sieve with a 12 inch
diameter? - CORRECT ANSWER -Shouldn't exceed 7 KG Dash M2) (4g/in2) of sieving surface
Describe how seives should be cleaned - CORRECT ANSWER -
For 600 (no .30) and larger use a course wire brush to clean. 600 and smaller use a soft bristle
brush.
What should be done to protect the 75 (no. 200) sieve during washing. - CORRECT ANSWER -
Use care not to overflow or overload
Once a washed sample is placed in the oven and dried to a constant mass, what is the next ste
p? - CORRECT ANSWER -Place sieves in mechanical shaker.
For how long should material be sieved on the shaker? - CORRECT ANSWER -10 mins
For how long must samples be submerged prior to determine the immersed weight for metho
d A - CORRECT ANSWER -4+-1 min
In determining the mass of a SSD specimen, how must a sample be dried? -
CORRECT ANSWER -
The sample must be removed quickly and dried with a damp towel within five seconds
At what temperature and for how long should or samples be dried? - CORRECT ANSWER -
125+-5 degrees over night than 2 hour intervals after
Standardization procedure for bowl - CORRECT ANSWER -
Fill the water bath to overflow level, water temperature at 77°+-
, 2°F allow it to stabilize, zero/tear, suspend the bowl for 10+-
1 minute determine and record the submerged weight of the bowl and sample to the nearest
0.1 G
Standardization procedure for pycnometer/volumetric flask - CORRECT ANSWER -
Immediately fill the pycnometer/volumetric FlaskHwith water without air, stabilized temp to 77
+ -2°, finish filling flask when at temp, please glass plate over the top to eliminate air.
What temperature should the sample be for testing - CORRECT ANSWER -
Cool sample to room temperature
Removing entrapped air from the container and sample by a partial vacuum is done for how lo
ng? - CORRECT ANSWER -15+ -
2 minutes, agitate sample by vigorously shaking with 2 minute intervals
How and why is he container and sample agitated? - CORRECT ANSWER -
Vigorously shaking at two minute intervals, this releases remaining air bubbles

CORRECT ANSWER -1000 G
The sample shall be initially dried for blank minutes - CORRECT ANSWER -90+-5
Further drying shall be in blank minutes intervals - CORRECT ANSWER -30+-5
How is constant mass defined for this procedure? - CORRECT ANSWER -
After further drying is done and the mass hasn't changed more that 0.05% final mass is determ
