Three-point vs four-point bend testing
In a three-point bend test, force is applied at a single midpoint. In a four-point bend test, two loading noses distribute the load over a larger section of the specimen.

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.

What is fastening torque
Fastening torque refers to the rotational force applied to tighten a fastener, typically measured in Newton-metres (N·m) or pound-force inches (lbf·in). The correct torque value ensures adequate clamping without overstressing components.
