ANSI/B11 B11.17-2004 (R2009)
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.
