18.104.22.168 Forms 3a and 3b. The specification number, MIL-type, size, date
of processing and lot control number shall appear on the flange of the spool so
as to be visible when the spool is positioned on the machine for welding. Such
identification shall be placed in a manner that Is not readily removable.
22.214.171.124 Forms 3c, 3d, 3e and 4. Tags made of material suitable for
resisting effacement or destruction and bearing the specification number,
MIL-type, size, date of processing and lot control number shall be firmly
attached at inner end of the coiled filler metal. Coils wound on supports shall
be identified with the above information placed directly on the support member
in such a manner as not to be readily removable. Filler metal wound in drums
shall be identified with the above information placed directly on the drum in
such a manner as not to be readily removable.
3.7 Form 6 (cut-length rods).
3.7.1 Tolerance (diameter size). Rods shall not vary from the nominal
diameter by more than plus 0.002 inch, minus 0.003 inch.
3.7.2 Length. The length of rods shall be 12, 18, or 36 inches plus O,
minus 1/2 inch except that for 36-inch length rods up to 10 percent of rods in
any container may be shorter than 36 inches, but not shorter than 24 inches.
Unless otherwise specified (see 6.2.1), the 36-inch length shall be furnished.
3.7.3 Identification. Cut-length rods shall be identified by positive
and legible methods such as imprinting or indenting the applicable type desig-
nation number (see detail specification) at one or more locations on the rod
surface approximately 1 inch from rod end, or shall be identified by pressure-
sensitive , plastic-coated tape imprinted with applicable type number at one or
more locations and attached to the rod approximately 1 inch from its end.
Imprints on rods or on tape shall be with fade-proof ink and shall be resistant
to oils, solvents, all atmospheric conditions, and to normal wear and tear
encountered in shipping and handling.
3.7.4 Production equipment. When a change is made in a production run of
one MIL-type rod to another, inspection shall be performed prior to starting the
new run to assure that equipment and process lines are purged of material needed
to be changed from the previous production run. This inspection shall be per-
formed for all equipment used in manufacturing operations where the material is
not segregated and positively identified (for example, cutting to length).
