The requirements of this standard apply to those mechanically, hydraulically or direct drive machines that are designed, modified, or converted for the purpose of compressing metallic or nonmetallic powders. These machines are commonly referred to as metal powder presses, powder metal presses, compacting presses, pill presses, rotary PM presses, PM briquetting presses, powder metal forging presses, metal powder sizing presses or metal powder coining presses. For the purpose of this standard, they shall be referred to as ""PM presses."" PM press axes can be of a direct driven type. Excluded from this standard are: mechanical and hydraulic power press brakes; mechanical and hydraulic power presses; bulldozers; conventional hot bending and hot metal presses; conventional forging presses; hammers; riveting machines and similar types of fastener applications; isostatic and hydrostatic presses; high energy rate presses.
