and size of the item and no matter how small the quantity. Lots shall simply be numbered UVW97F001S001, UVW97F001S002, etc. When UVW98D001S999 is reached the producing facility shall continue numbering by merely changing the interfix to 002. The next "special lot" of these types would then be UVW98E002S001, etc. The following exemplifies this type of lot numbering.
Example:
A quantity of grenade bodies is diverted from an assembly line and is loaded with an inert filler in lieu of an explosive bursting charge. A standard line fuze is then assembled to the inert loaded grenade bodies. This special lot is being assembled for use in special tests. Lot number UVW97K001S001 will be assigned. At the same plant a special lot of a completely different item is prepared. Despite the different item and because it is a special lot, this lot number will keep the same interfix and be UVW97L001S002. (No national stock number shall be assigned/used for these special lots. The sole identification for these lots shall be the complete nomenclature and the lot number.)
The authority for creation of the special lot, how it is to be used, where to be used, the test project designation, and all other information pertinent thereto shall be cited in the remarks block of the ADC. Ammunition designated as special lots shall not be issued for field use nor flow into the regular supply stream without special and specific authorization.
4.7.9 Regrouped lots (includes blended propellant lots). (The "G" lots). The "G"
lots shall be identified by replacing the hyphen between the lot interfix number and the lot sequence number with a capital letter "G." Regrouping is when two (2) or more complete round lots are combined to form one (1) lot. Regrouping shall only be authorized (see 6.13.c) and occur when the items do not, or no longer, follow the principles of homogenous lotting. Examples of this include: purchases of commercial items for which the lotting practices are unknown; items affected by actions, such as rework or maintenance, to the extent that the original lotting concepts are destroyed; and when there has been a loss of lot visibility. Regrouping can occur, provided the above requirement is met, regardless of type of operations which may or may not be performed in conjunction with the assemblage of these lots. The regrouping action may or may not include modification, conversion, overhaul, propellant blending, or extensive maintenance. Work may be performed at LAP facilities, depots, bases, etc.
4.7.9.1 Regrouped lots - documentation. When regrouping is performed, a completely new lot number shall be assigned, and a new ADC created. In all such actions, detailed comments shall be inserted in the remarks portion of the data card including a listing of the former lot(s) when available and the actions being performed.
4.7.9.2 Regrouped lots - lot number assignment. New lots shall be formed in accordance with the requirements of the regrouping directive. Lot numbers shall be assigned in the normal manner with the interfix numbering beginning at "001" and
