 Alternate marking methods are permissible provided such method is
an available option delineated by applicable specifications or
drawings.
(1) Markings shall be legible.
(2) Markings shall be so located as to not affect the
form, fit or function of the item.
(3) Markings will be permanent whenever the type, size
and condition of the material permits.
(4) Piping will be marked 1 inch from each end.
(5) Small uninstalled items whose type or condition
preclude the use of permanent markings shall be
identified as follows:
(a) Package in two "clean" clear bags (i.e., double
bag) and label the bag with the required
traceable I.D. number.
(b) Items with the same I.D. number (e.g., same lot
of fittings, o-rings) may be packaged for
storage in the same bag.
(c) Items removed from the bag for installation
shall be documented by recording the I.D.
number on the applicable REC sheet.
(6) Marking number format is at the discretion of
individual commands. Sequential three digit numbers
preceded by the year the material is received is
recommended (e.g., MIC-86-001, MIC-86-002, etc.).
All MIC marking numbers shall be preceded by "MIC"
to identify the purpose of the marking.

Cleaning.
a.
Prior to storage, items such as valves,
fittings, hoses, gauges, etc., shall be cleaned per approved
cleaning procedures (OQE cleaning documentation from vendor is
acceptable).
b.
Storage. Materials shall be stored in a suitable area
specifically designated for the storage of life-critical components
and materials. Access to such storage area shall be controlled to
prevent inadvertent tampering with these materials.
Material Control During Fabrication and
5.2.5
Installation. Materials requiring installation only and which have
permanent MIC I.D. numbers require no special attention other than
following approved installation and REC procedures. Materials
requiring additional control awareness are:
Piping. Prior to cutting, MIC I.D. markings shall be
placed one (1) inch from the cut on both sides of the cut.
