What is bulk analysis testing?
Definition and purpose
Bulk analysis testing assesses the mechanical properties of particulate materials as a collective whole, rather than analysing individual particles. This includes powders, granules, pellets and similar materials.

What is torque testing?
Torque testing measures the rotational force required to turn or twist an object. In packaging, it is most often applied to closures such as caps, lids and twist-top mechanisms to ensure they open and close within defined performance limits.
