1 scoPE
This Standard provides performance and safetyrequirements for ball peen hammers.Ball pecn 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 selectirg, 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 gutide 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 reguJatory bodies in the formulation of lawsor regulations. It is also intended for voluntary use byestablistments that use or manufacture the tools cov-ered. The methods ernployed to ensure compliance withthis Standard shall be determined by the proper regula-tory or administrative authority.

Pammernead: the portion of the hammer exchusive of thehandle.
handte: the portion that protrudes from the hamner headand by which the tool is held.
handle grip: material securely attached to the grip endof some styles of harrrner handles.
ha rdness: the condition of the hammer head resultingfrom heat treatment.
ecks: the portions of the hammer head located betweenthe bell arid the eye, and the ball peen and the eye.safety message: the information inprinted on or affixedto the hanmer to prornote safety.
shall: indicates mandatory requirements of thisStandard.
hozfat: indicates if a provision is of an advisory natureor is stated as a recorninendation.
sides for cheeks): outside surfaces of the hammer headon either side of the eye located between the two necks.spalling: chipping or separation of material.
striking face: the portion of the hammer head, exclusiveof the neck, bell, and chamfer. lo:ated on the side of theeye opposite fron the ball peen.
striking face croin: the convex shape or radius of thestriking face.
top of hanmer: the portion of the hanrmer directly oppo-site the handle.
wedged hanimer : a hammer that has the handle securedto the hammerhead by inserting a device to expand thehandle within the eye.
REQUIREMENTS4.1 Design
Ball peen harnners shall have a striking face on oneend of the head for use in staking punches and chisels,and a ball pcen on the opposite end for use in riveting.shaping and straightenirg unhardened metals.
iThe stnking face shall have a convex shapc.(b)The ball peen shall have a stroathly contouredshape that is approximatcly hemispherical.
() The striking face shall have a chamfcr of approxi-mately 15 deg (or equivalent radius) around the perime-ter with a width equal to appIoximately one-tenth thediarneter of the bell as measured across the chamferangle. For example, if the bell diameter equals ] in., thenthe chamfer width equals approximately 0.10 in.
(d)Hammers shall pass the tests specified in para. 5.(e Thc hcad and handle shall be free of nonfunctionalsharp edges,points, and surface roughness that couidinflict personal injury on the user when handling theharnmer.
4.2 Materials
The materials used in the manufacture of hamnersshall be as such to produce hammers conforming to therequirements specified herein.
4.3 Mechanical Properties
ta) The striking face shail be hardened and temperedto 45 HRC to 60 HRC or equivalent.
b) The ball pcen shall be hardened and tempered to45 HRC to 60 HRC or equivalent.
s TESTS
Many tcsts required herein are inherently hazardousand adequate safeguards for personnel and propertyshall be employed in conducting such tests.
Samplc hamners shall be tested and shall corforrto the requinments of all applicable tests specificd inparas. 5.1 through 5.5. Separate (new) sarmples shali beused for each of the tests. Failure to meet the require-ments of any one of the tests indicatcs the hamners donot comply with this Standard.
