Title
APPLYING DATA MATRIX IDENTIFICATION SYMBOLS ON AEROSPACE PARTS
NASA - National Aeronautics and Space Administration
Publication Date:
Jun 20, 2008
Scope:
This standard and its related handbook, NASA-HDBK-6003,
Application of Data Matrix Identification Symbols to Aerospace
Parts Using Direct Part Marking Methods/Techniques (DPM), were
developed to provide NASA and its contractors with instructions to
safely apply Data Matrix identification symbols to aerospace parts
using these new DPM methods and techniques. Both the standard and
the handbook were created by representatives from the major
automatic identification and data capture (AI/DC) manufacturers,
Government, and aerospace user groups under a collaborative
agreement with NASA. The standard has been approved by NASA
Headquarters for use by all field installations, and is intended to
provide a common framework for consistent practices across NASA
programs.
Revision B of this standard included updates stemming from the
Department of Defense (DoD)/National Center of Manufacturing
Sciences (NCMS) Retrograde Part Marking Program as approved by the
Assistant Under Secretary of Defense, and the United States Coast
Guard (USCG) Data Matrix Direct Part Marking Flight Verification
Program, which was sanctioned by the Flight Safety Critical
Aircraft Part Problem Action Team (FSCAP PAT) and the U.S. Congress
Aircraft Safety Committee. Revision B planning had called for the
incorporation of information resulting from the Materials
International Space Station Experiment (MISSE), which exposed the
Data Matrix Symbol markings to low-earth orbit (LEO) environments.
However, due to delays in the retrieval of the MISSE experiment,
information related to marking processes certified for LEO are to
be incorporated into a later revision of this document. MISSE
program information is included in Appendix A.
Purpose
This standard establishes uniform requirements for applying Data
Matrix identification symbols to parts used on NASA
programs/projects using DPM methods and techniques. Overall
program/project requirements related to the use of the Data Matrix
symbol include symbol criteria, marking method selection, marking
surface preparation, marking location, protective coatings, marking
environments, and mark-quality verification standards. This
document does not specifically address the marking of
human-readable characters or temporary part identification markings
(bands, labels, or tags). On new programs, human-readable
characters can be applied using the same marking methods defined in
this standard. Data Matrix symbols can be added to parts used on
existing programs if there is adequate area to accommodate the mark
and the structural integrity of the part is not compromised.
This standard is intended to provide general requirements for
applying Data Matrix identification symbols safely onto products
using permanent DPM methods and techniques. The standard addresses
symbol structure only as it relates to marking and reading
limitations. Technical specifications related to the Data Matrix
symbol are found in Automatic Identification Manufacturers (AIM)
International, Inc., technical specification titled "International
Symbology Specification – Data Matrix." Technical information on
how to apply the markings is addressed in NASA-HDBK-6003.
Applicability
This standard is applicable to NASA programs/projects using DPM
methods and techniques. In all cases when identification is being
applied to flight hardware, the responsible Technical Authority
shall approve the location of the mark and the method used to apply
it.
This standard may be cited in contract, program, and other
Agency documents as a technical requirement. Mandatory requirements
are indicated by the word "shall." Tailoring of this standard for
application to a specific program or project shall be approved by
the Technical Authority for that program or project.
This standard explains the use of Data Matrix symbol marking to
support updates to Automated Identification Technology (AIT)
systems used to provide program managers with real-time hardware
status. The standard provides engineering practices for NASA
programs and projects. Human-readable markings applied to NASA
aircraft maintained under Federal Aviation Administration (FAA)
certificate such as Part 121 or Part 135 shall comply with Title 14
of the Code of Federal Regulations. Data Matrix marking shall be
used to identify all flight hardware and ground support equipment,
including, but not limited to, the following:
• Calibration items
• Critical fasteners
• Fracture-critical parts
• Hazard analysis items
• Items requiring periodic maintenance
• Limited-life items
• Pilferage items
• Repair-limited items
• Restricted-use items
• Safety-critical Items
• Temporary installations
• Other items identified with paint dots or assigned date codes,
lot numbers, member numbers, or serial numbers (S/Is) for safety,
reliability, maintainability, or quality assurance purposes,
including items not currently serialized due to size limitations
associated with the applications of human-readable marking.
This standard shall not be used for electrical, electronic, and
electromechanical (EEE) parts identification and marking
requirements due to concerns relating to electrostatic discharge
and component degradation. EEE part marking and identification are
addressed in the military standards for the specific part
types.
