MIL-STD-130N
(1) applied to a supplemental container that may or may not provide item protection, becomes a part of the individual item, and is provisioned and managed as a component of that item, or
(2) applied to the unit pack in addition to, or in combination with, the identification marking information specified in MIL-STD-129. When combining marking requirements with MIL- STD-129, the manner, method, form, and format of MIL-STD-129 shall be followed and the informational requirements of this standard shall be fulfilled.
4.2 Location, size, and content. Whenever practicable, the location of the marking on the item shall ensure its readability during normal operational use. Marking size shall satisfy the legibility requirements of 4.3. All aspects of item identification marking shall be specified directly or by reference on the document delineating the item to be marked.
4.3 Permanency and legibility. Direct identification marking and identification plates, identification bands, identification tags, or identification labels used shall be as permanent as the normal life expectancy of the item and be capable of withstanding the environmental tests and cleaning procedures specified for the item to which it is affixed. The direct identification marking method should be selected to ensure the mark will withstand the specified rebuild processes. It is not intended that existing items be subjected to retest solely because of the addition of an MRI requirement except when required to insure compliance with 4.5. When
IUID is required for new items that are being tested, the marking on the part shall be subjected to the same test conditions. Direct identification marking methods shall account for final finished condition of the item including paints, coatings, and sealants to assure readability.
a. If it is not feasible to mark an item with MRI that will survive its intended life cycle, including the rebuild process when applicable, the item shall be marked in a way that will survive its anticipated life cycle up to the point of rebuild. The rebuild process must then ensure that the UII is linked with the item until the part can be remarked with the original UII data prior to leaving the rebuild facility.
b. Legibility shall be as required for human readability. For human-readable information, which is not prescribed by one of the applicable MRI protocols in 5.2.2, the recommended minimum character height for human readable text is shown in Table I.

4.4 Identification plates, identification tags, and identification bands. Metal and stiff plastic identification plates, tags and bands, along with their attaching provisions, shall conform with the requirements of MIL-DTL-15024, MIL-DTL-19834 or GG-P-455 as applicable, to the extent specified in the contract or order.
4.5 Deleterious effect. Marking of items shall be accomplished in a manner that will not adversely affect the item's ability to meet its required performance.
4.6 Abbreviated information. When size limitations, adverse impacts, or other considerations preclude marking all applicable information on an item (i.e., some marking space
