The following machines are included in the scope of this standard:

a) Single-spindle automatic bar machines of the tool turret-indexing type;
b) Single-spindle automatic machines of the sliding-headstock type, or those with a fixed headstock and a sliding guide bushing (Swiss-type);
c) Single-spindle automatic machines of the tool- rotating type;
d) Single-spindle automatic chucking machines of the collet and chuck types;
e) Multiple-spindle automatic bar machines;
f) Multiple-spindle automatic chucking machines of the collet and chuck types.

Excluded from the scope of this standard are machines that are manually controlled, such as, but not limited to: lathes, engine lathes, tool room lathes, vertical-shaft lathes, copy/tracer lathes, gap and sliding-gap lathes, and combination lathes.

The purpose of this standard is to establish safety requirements with respect to the design, construction, safeguarding, and use of single-spindle or multiple-spindle automatic bar and chucking machines. An additional purpose of this standard is to assign safety and risk reduction responsibilities for both the supplier and user.
