4.2 Support of Test piece
The heavy workpiece do not need support
The Mid-heavy workpiece must be placed on a flat, sturdy surface, and
absolutely smooth placement, without any shaking.
Light workpiece must be tightly coupled with the solid support body, the
coupling surface must be smooth, and Coupled dosages don’t too much,
Test direction must be perpendicular to the coupling surface.
When the workpiece is a large area of Sheet, Pole and Bending Parts,
Even if a large weight and thickness may still cause deformation, so
reinforcement and support in the rear surface of the test point is necessary.
