scope:

General. This standard applies to machines constructed with a plate- or cast-type ram, or both, bed, table, hold-down, and housings, utilizing one fIXed and one moving nonrotary blade for the shearing action, and having a constant rake for anyone shearing stroke. The standard applies to shears designed primarily for metal shearing. It also applies to shears designed for shearing other types of material and having the basic . configuration just described.
