The flow properties of a powder or bulk solid determine how it behaves during handling. A motor moves the shear cell relative to the lid in order to apply shear to the sample. For compaction (pre-shearing) the sample is subjected to a large normal force. In a ring shear tester, a bulk sample is contained in a ring-shaped shear cell. A normal force is exerted on the sample by way of a lid. A hanger from which a variable weight is suspended generates this normal force. For example, material may flow irregularly out of silos, or the flow of bulk solid may come to a stop. In order to avoid these problems in practice, soils can be designed on the basis of measurements using shear testers, such as the Jenike shear tester or a ring shear tester. From the shear force characteristics, properties such as the compressive strength and internal friction of the bulk solid can be determined. An electronically amplified force transducer measures the shear forces which are then recorded by data acquisition software over time. To determine the density of the bulk solid, the volume of the bulk sample is ascertained by recording the lowering of the lid using a vernier caliper gauge. After pre-shearing, shearing to failure is executed with a reduced normal force (strength measurement) and likewise recorded by the software.

Greener Choice Claims
Environmental benefits include:
Recyclable.
Made of breathable SMS fabric, the coveralls feature a high-neck collar, a zipper flap, thumb loops and bound seams
Coveralls feature a polypropylene breathable SMS fabric with a cloth-like feel.
In addition, this protective apparel is recyclable through the RightCycle program (by Professional).
This personal protective apparel is triple-bagged and vacuum packaged, suitable for cleanrooms. It is not made with natural rubber latex, silicone, or the BHT preservative and is designed for single-use (disposable PPE).
Cleanroom Coveralls are made of 100% polypropylene breathable SMS fabric, which gives the wearer cloth-like comfort. While other coveralls for cleanroom environments may look similar, the ones from Pure have distinct advantages including tightly bound seams to strengthen the barrier, a high neck collar to reduce contamination, thumb loops to keep the sleeves from rolling back and a zipper flap to cover the zipper area.
