4.4.4.2 Wet mix test. The manufacturer shall perform sufficient tests
before and after application of the covering to assure that all wet mixes of
covering mixture in the lot are equivalent. The test procedures and results of
tests shall be recorded, These test procedures shall be made available to the
Government representative and to the consignee on request (see 6.3). Wet mix
identity shall be maintained as required by 4.4.6.
4.4.5
Inspection level D.
4.4.5.1 Lot.
For the purpose of selecting samples for quality conformance
inspection, a lot of electrodes is defined as the quantity of any one size and
type produced from core wire specified in 4.4.1.3 or 4.4.1.4.2, or during a 24-
hour working period (or three consecutive normal work shifts).
4.4.6 Lot identification. Lot identification shall be accomplished by
marking each unit and shipping container with a unique manufacturer's control
number. If these control numbers are encoded, the manufacturer shall furnish the
interpretive key to the consignee. This control number shall be in a position
which permits ready location by the consignee and shall contain the following
information for each inspection level/lot classification:
4.4.6.1 Inspection levels A, B and C. When identification is by heat of
core wire as defined in 4.4.1.3 and wet mix as defined in 4.4.1.1.3, each heat of
core wire and each wet mix shall be identified.
4.4.6.2 Inspection levels A and B. When lot identification is by
controlled core wire chemical composition as defined in 4.4.1.4.2 and controlled
covering mixture chemical composition as defined in 4.4.1.2.2, each continuous
4-hour working period shall be identified.
4.4.6.3 Inspection level C. Where lot identification is by controlled core
wire chemical composition as defined in 4.4.1.4.2 and controlled covering mixture
chemical composition as defined in 4.4.1.2.2, each continuous 8-hour shift shall
be identified.
4.4.7 Sampling and inspection ofcontainers. Unit packages, sealed cans,
and shipping containers shall be sampled and inspected in accordance with
MIL-W-10430.
4.4.8 Sampling for quality conformance inspection. Sample electrodes shall
be selected either from filled unit packages or from the production line after
the backing operation except where otherwise specified (see 3.1). The unit pack-
ages required for this examination may be selected from the sample of packages
used for 4.4.7. If sample electrodes are selected from filled unit packages or
cans, the total sample shall be in accordance with Schedule A of the following
table for electrode sizes l/8-inch and larger and Schedule B for electrode sizes
3/32-inch and smaller for single sampling, and approximately the same number of
electrodes shall be selected from each of the unit packages or groups of cans
(6 cans per group). Lot size shall be expressed in pounds.
Sample size shall be
the number of electrodes to be examined, A minimum number of unit packages shall
be selected to permit sampling of ten electrodes maximum from each 50-pound
package or from each 10-pound package. If the sample electrodes are selected
from the production line, the total sample shall be equivalent to the above and
