, Performance Checklist:
Sampling of Aggregates:
Flowing Aggregate Stream (Bins or Belt Discharge)
5 steps - CORRECT ANSWERS-1. Use a device that will hold the required amount of
material without overflowing.
2. Take each increment from the entire cross section of the material discharge stream
3. Obtain a minimum of three approximately equal increments.
4. Combine the increments to form a field sample.
5. Ensure that the size of the field sample equals or exceeds the approximate minimum
mass needed or stated in Table 1.
Performance Checklist:
Sampling of Aggregates:
Conveyor Belt
7 Steps - CORRECT ANSWERS-1. Stop the conveyor belt and insert two templates
conforming to the shape of the belt into the aggregate steam.
2. Space the templates so the material between will yield an increment of the required
mass.
3. Carefully scoop the material between the templates into a suitable container.
4. Collect the fines with a brush and dust pan and add to the container.
5. Obtain a minimum of three approximately equal increments.
6. Combine the increments to form a field sample.
7. Ensure that the size of the field sample equals or exceeds the approximate minimum
mass needed or stated in Table 1.
