The requirements of this standard apply to those horizontal hydraulically 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. Included are horizontal hydraulically powered presses that produce extruded shapes by the extrusion process, either direct or indirect.

Excluded from the requirements for this standard are: hydrostatic extrusion presses, vertical extrusion presses, laboratory presses used to develop extrusion techniques for new materials and products, and extruding machines of unconventional design.
