1 sCOPE
This Standard provides performance and safetyrequirements for ball peen hammers.Ball peen hammershave a striking face on one end of the head for use instriking punches and chisels,and a ball peen on theopposite end for use in riveting, shaping. and straight-ening unhardened metals. This Standard is intended toserve as a guide in selecting, testing, and using thehand tools covered herein. It is not the purpose of thisStandard to specify the details of manufacturing.
This Standard is also intended to serve as a guide forthe development of manuals and posters and for trainingpersonnel to work safely.
This Standard may be used as a guide by state authori-ties or other regulatory bodies in the formulation of lawsor regulations. It is also intended for voluntary use byestablishments that use or manufacture the tools cov-ered.
