1 SCOPE This Standard provides performance and safety requirements for ball-peen hammers. Ball-peen ham- mers have a striking face on one end of the head for use in striking punches and chisels, and a ball peen on the opposite end for use in riveting, shaping, and straightening unhardened metals. This Standard is intended to serve as a guide in selecting, testing, and using the hand tools covered herein. It is not the purpose of this Standard to specify the details of manufacturing. This Standard is also intended to serve as a guide for thedevelopmentofmanualsandposters and fortraining personnel to work safely. This Standard may be used as a guide bystate authori- ties or other regulatory bodies in the formulation oflaws or regulations. It is also intended for voluntary use by establishments that use or manufacture the tools cov- ered. The methods employed to ensure compliance with this Standard shall be determined by the proper regula- tory or administrative authority. 2 DEFINITIONS (See Fig. 1 as applicable.) ball peen: the rounded portion of the hammerhead directly opposite the striking face. bell: the portion of the hammerhead directly behind the striking face. chamfer: the bevel or equivalent radius encircling the perimeter of the striking face. equivalent: indicating alternate designs or features that will provide an equal degree of performance and safety. eye: an opening or aperture located between the ball peen and striking face into which the handle is inserted, if the handle is separate. hammerhead: the portion of the hammer exclusive of the handle. handle: the portion that protrudes from the hammerhead and by which the tool is held. handle grip: material securely attached to the grip end of some styles of hammer handles. hardness: the condition of the hammerhead resulting from heat treatment. necks: the portions of the hammerhead located between the bell and the eye and the ball peen and the eye.
safety message: the information imprinted on or affixed to the hammer to promote safety. shall: indicates mandatory requirements of this Standard. should: indicates if a provision is of an advisory nature or is stated as a recommendation. sides (or cheeks): outside surfaces of the hammerhead on either side of the eye located between the two necks. spalling: chipping or separation of material. striking face: the portion of the hammerhead, exclusive of the neck, bell, and chamfer, located on the side of the eye opposite from the ball peen. striking face crown: the convex shape or radius of the striking face. top ofhammer: the portion of the hammer directly oppo- site the handle. wedged hammer: a hammer that has the handle secured to the hammerhead by inserting a device to expand the handle within the eye. 3 REFERENCES The following is a list of publications referenced in this Standard.

4 PERFORMANCE REQUIREMENTS 4.1 Design Ball-peen hammers shall have a striking face on one end of the head for use in striking punches and chisels, and a ball peen on the opposite end for use in riveting, shaping, and straightening unhardened metals. (a) The striking face shall have a convex shape. (b) The ball peen shall have a smoothly contoured shape that is approximately hemispherical. (c) The striking face shall have a chamfer of approxi- mately 45 deg (or equivalent radius) around the perime- ter with a width equal to approximately one-tenth the diameter of the bell as measured across the chamfer angle. For example, if the bell diameter equals 1.0 in., then the chamfer width equals approximately 0.1 in. (d) Hammers shall pass the tests specified in section5. (e) The head and handle shall be free ofnonfunctional sharp edges, points, and surface roughness that could inflict personal injury on the user when handling the hammer. 4.2 Materials The materials used in the manufacture of hammers shall be as such to produce hammers conforming to the requirements specified herein.
