Purpose

This procedure determines the angle at which a bottle will tip and fall once the center of gravity has been overcome on tilting.

Description

A tilt test device is fitted with the appropriate surface. The test device is then tipped until a test bottle breaks the plane of contact because the center of gravity of the bottle has been overcome. The angle at which this tipping occurs is considered the tilt angle. Typically, twelve bottles are tested and the average tilt angle is determined for the set of bottles.
