Class 086
AMMUNITION AND EXPLOSIVE- CHARGE MAKING
Class Definition:
Instruments and processes peculiarly adapted for making fixed
ammunition, including percussion caps, cartridges, or other
explosive charges for firearms or ordnance, pyrotechnic
devices, blasting charges, etc.
(1) Note. This class also takes subject matter closely
related to ammunition and explosive-charge making, when not
elsewhere provided for, including ammunition shell unloading
and bomb disposal (see Subclass References to the Current
Class, below).
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Such single operations as rolling, turning, milling, boring,
forging, casting, molding, coating, die-shaping, drawing,
extruding, even though applied to manufacture of ammunition,
are classified in appropriate functional classes. Making
projectiles or other metal parts of ammunition by general
metal-working operations is in appropriate metal-working
classes. An operation of making a paper tube or paper body
generally is in Class 493, particularly subclasses 269+ even
though applicable to manufacture of cartridge cases.
SEE OR SEARCH THIS CLASS, SUBCLASS:
49 for ammunition shell unloading.
50 for bomb disposal.
