18.104.22.168 Sampling for visual examination or rods and electrodes. Sample rods
and electrodes shall be selected either from the production line immediately prior
to packaging or from filled unit packages. If selected from the production line,
the total sample shall be in accordance with table V and the electrodes or rods
shall be selected throughout the run so that all parts of the run are represented.
If selection is made after the packaging operation, the total sample shall be in
accordance with table V and approximately the same number of electrodes or rods
shall be selected from each of the sample unit packages (five cut-lengths (rods)
of each package) and sufficient electrode to form one complete circle shall be
taken from each sample spool, coil and drum.
Sampling for visual examination.
22.214.171.124 Any sample coil, spool, drum or box which contains any nonconforming
material snail be counted as defective. If in any sample the number of coils,
spools, drums or boxes which do not conform to this specification exceeds the accep-
tance number specified in table V, this shall be cause for rejection of the lot.
126.96.36.199 Sampling for cast and helix tests. Specimens shall be cut from
spools and coils selected in accordance with 188.8.131.52 and table V and shall be
tested and evaluated as specified in 3.6.4. If any specimen fails the tests,
the tests shall be performed on every spool or coil of the lot (see 184.108.40.206 as
applicable), and all failures shall be rejected.
220.127.116.11 Sampling for chemical analysis. One specimen shall be selected
from the lot (see 4.5.1 or 4.5.2) and chemically analyzed to verify conformance
to the required chemical composition specified in the detail specification.
When more than one production line is being used to deposit copper coating on a
single lot of electrodes, the following procedure shall be conducted in addition
to the usual chemical composition conformance test:
Sample the product of each line at least once each shift.
Analyze for copper coating and record each result.
Identify the product of each line.
Purge nonconforming material prior to shipment.
