A procedure is provided for evaluating the score, snap and edge appearance of wallboard panels, and includes scoring a wallboard panel with a knife at a constant and known force using a benchtop board scoring device; snapping the scored panel in a Universal Board Testing Machine to measure the breaking force, forming a snapped panel edge; measuring a cleanliness of the snapped panel edge by placing a straight edge against the snapped panel edge and measuring gaps between the snapped panel edge and the straight edge in a plurality of locations on a face of the panel, and a plurality of locations on a back of the panel; and averaging all of the measured gaps to create an Index Score.

Wallboard score, snap and edge appearance test procedure

A golf club having shafts and club heads comprised of either: metals, composites, or ceramics which are gas permeable and possess the properties of hollows and cavities respectively. Whereas upon sealing the union of the shaft and the club head renders same air tight. Further, introducing a gas induction valve at the shafts upper end thereby enabling gas induction while also providing a check valve seal to prohibit gas loss after pressurization provides a hermetically sealed golf club. This art applies to any provider of golf club components meeting these generic requirements. Whereas the compilation of components aforementioned while inducing compressed gas dependent upon the type golf club, will enhance the performance of any golf club so modified.
