MSE SOP:Density Measurements
Safety
A&D 2000 with the QCD-1 Specific Gravity & Porosity Measurement System
Located in the sand lab in the foundry
-Proper PPE must be worn
-Steel Toe Shoes
-Safety Glasses
-Greens Jacket
-Nital Gloves (recommended)
Procedure
1) Turn on the A$D 2000 using the ON/OFF button located on the right
2) Remove the hanging platform from the inside of the bowl so that the bowl can be removed (A larger bowl can be used if needed)
3) Fill the bowl halfway with distilled water,(distilled water is located in the investment lab on the North wall)
4) Place the bowl on the lower platform and place the hanging platform in the water so that it does not touch the sides of the bowl (the entire platform should be submerged)
5) Zero the scale using the red button in the bottom right corner
6) Place the sample on top of the arm that holds the suspended platform
7) Once the value stabilizes, press the button labeled "SAMPLE"
8) Remove the sample from the arm and place it in the water on the platform. (The entire sample should be submerged)
9) Once the value stabilizes, press the sample button and the density value will be displayed on the screen
10) Press "SAMPLE" button to clear density value to continue with further measurements
