ASME B107.47M:1998 pdf free download METAL CHISELS: SAFETY REQUIREMENTS
1 GENERAL
1. Scope
This Standard provides safety requirements for thedesign,construction,testing.and use of hand-held andhandled metal chisels that are intended specifically foruse in cutting and shaping metal objects.Some typesof chisels included are cape.cold,concave, splitting,diamond point,and half-round. Power-driven chiselsare excluded.
1.2 Purpose
This Standard is intended to serve as a guide inselecting.testing. and using the hand tools covered.Details of design,testing, and use of the tools coveredare specified only as they relate to safety. it is not thepurpose of this Standard to specify the details ofnanufacturing.
This Standard is also meant to serve as a guide indeveloping manuals and posters and for training person-nel in safe practices.
1.3 Application
This Standard may be used as a guide by stateauthorities or other regulatory bodies in the formulationof laws or regulations. It is also intended for voluntaryuse by establishments that use or manufacture the toolscovered.

3 DEFINITIONS (See Figs. 1 and 2 asApplicable)
For the purpose of this American National Standard,the following definitions apply.
bevel:the angular portion of the chiscl adjacent tothe cutting edge extending to the taper.
body: the straight portion of the chisel between thechamfer and the taper.
chamnfer: the angled flat surface or equivalent radiusbetween the “struck face and the body of the chiselencircling the perimeter of the struck face.
cutting edge: the edge formed by the bevel directlyopposite the struck face.
eye: an opening or aperture located in the body ofthe chisel into which a handle is inserted (in thosechisels designed for handles).
hand-held chisel: a chisel intended to be held byits body.
handle: the portion protruding from the chisel bodyby which the tool is held (in those chisels designedfor handles).
hardness: the condition of the chisel resulting fromheat treatment.
rourded head:an equivalent design for the struckface and chamfer portion of the chisel.
safety message: the information imprinted on or af-fixed to the chisel that is intended to promote safety.struck face: the portion of the chisel exclusive of thechamfer and body， directly opposite the cutting edge.taper: the portion of the chisel between the body andthe bevel with a gradually reducing cross-sectional area.upse head: the portion of the chisel body having anenlarged cross-sectional area at the struck end of thetool. including and underlying the struck face.
