4.5.1 Lot definition of bare solid electrodes.
18.104.22.168 Lot. For the purpose of sampling and inspection, unless otherwise
specified in the detail specification, a lot of electrodes or rods shall be the
quantity of one type alloy produced as specified in either 22.214.171.124.1 or 126.96.36.199.2.
188.8.131.52.1 Lot identification by heat of metal. were manufacturing
processes are such that wire is identified by a heat of metal, the lot in
addition to 184.108.40.206 shall be the quantity produced from a single heat of metal.
220.127.116.11.2 Lot identification by controlled wire chemical composition.
Where manufacturing processes are such that wire is identified by controlled
chemical composition of each MIL-type (see 18.104.22.168), in addition to 22.214.171.124, a
lot of electrodes shall be the quantity produced from one or more chemically
tested mill coils from one or more heats of metal conforming to the approved
chemistry control limits for that type electrode. The following additional
conditions shall apply:
(a) Each continuously rolled mill-coiled rod furnished by mill
prohibiting spliced-coil practice, shall be chemically analyzed
by approved methods (see 126.96.36.199). Mill-coiled rod furnished
by mills permitting spliced-coil practice, shall have no more
than one splice per coil, and both ends of every coil received
from such mills shall be chemically analyzed before processing.
Chemical analyses shall be certified by the laboratory and made
available to the Government representative.
(c) Mill coils conforming to established wire chemistry control for
a specific MIL-type electrode shall be appropriately identified
and segregated to avoid mix-ups.
4.5.2 Lot definition of alloyed cored electrodes.
188.8.131.52 Lot. A lot of electrodes shall be the quantity of any size and
type produced from the following:
(a) One dry batch (see 184.108.40.206) or one dry blend (see 220.127.116.11) and
one heat of metal (see 18.104.22.168) not to exceed 25,000 pounds of
(b) Chemically controlled dry batches of alloy material (see 22.214.171.124)
and chemically controlled mill coils (see 126.96.36.199) not to exceed
100,000 pounds of electrodes.
188.8.131.52 Dry batch. A dry batch of alloy mixture shall be the quantity of
dry alloy ingredients mixed at one time in one mixing vessel. The dry batch
may be used singly or subsequently subdivided.
184.108.40.206 Dry blend. A dry blend shall be one or more dry batches mixed
in a mixing vessel and combined proportionately to produce a uniformity of
mixed ingredients equal to that obtained by mixing the same total amount of dry
ingredients at one time in one mixing vessel.
