Definition of Lotting
Lot:
A product of one run of production
Definition of Batch
Batch:
A group of components put together ie. 105mm
Cart case, primer, projectile, fuze, propellant
*Purposes of Lotting:
Ensure consistent performance under similar conditions Identify defective rounds ID and withdraw unserviceable components ID a definite QTY To facilitate maintenance of records
Current system of batching:
1969 Batching system
Ammunition can be formed into local lots, providing the ammunition is serviceable, what else must be assured:
Each local lot is confined to
nature, type and mark or model
Quantity is not to exceed normal production lot QTY
Marking categories:
Operational Practice Blank Dummy Instructional Experimental
*Why are markings applied to ammunition:
Provide all necessary manufacturing and filling details
Facilitate the issue of the correct nature and type of ammunition
Enable user to clearly ID under all conditions
Provide sufficient info for storage and transport
Provide a means of protection against corrosion
*Methods of identification:
Permanent markings (embossed) Overall body colour Wide band or discs identifying primary role Narrow band identifying hazard Non permanent markings Symbols ID labels, plates and tags
Overall body colour:
Coloured smk and WP:
Eau de nil
Incendiary:
Signal Red
Drill:
Oxford blue
Anti armour:
Black
*Items that do not require colour codes:
Charge/propelling bags Experimental ammo Sporting ammo Commercial ammo Display models Liquid propellant Dem stores
How are hazard codes indicated on projectiles:
Indicated by a narrow band or bands
Role coding colours:
Where a non significant overall body colour is used, the role band width is not to exceed one half the calibre, max width 50mm
