SCOPE

This method is intended to determine the force required to either bend or break a buckle in a direction at 90° to the plane of the buckle frame. The method is applicable to all types of buckle.

PRINCIPLE

A buckle is held horizontal by supporting both ends of its frame with straps attached to the upper jaw of a tensile testing machine while the central bar of the buckle is connected to the lower jaw. The jaws of the tensile testing machine are moved apart and the force required to either break or bend the buckle frame is measured.
