Gives square head industrial fluid power cylinders and provides requirements for: Design parameters for the determination of the theoretical static failure rating of pressure containing components; Properties of materials; Method of marking; Assembly and workmanship. Mountings, rod buckling, etc. are pertinent to proper cylinder application, but are considered beyond the scope of this document. It is intended to establish a basic method for calculating and assigning the static failure pressure rating to a cylinder which will be consistent and understandable to both the manufacturer and the user, but not intended to imply the maximum operating pressure of the cylinder.
