The requirements of this standard apply only to those horizontal powered presses that extrude metals by means of applying sufficient pressure to an individual metal billet, confined within a container, to force the metal to be extruded through the configured openings of a die, and includes any other equipment and system(s) used in the press production operation.

The horizontal extrusion press system, hereafter referred to as a press system, is a system that functions to extrude metals horizontally either by the direct or indirect process. It includes components necessary to handle and process metals from the loading mechanism through the platen exit or external butt shear through the process of cooling.
