NASA-STD-6002A Applying Data Matrix Identification Symbols on Aerospace Parts

National Aeronautics and Space Administration (NASA). This Technical Standard approved by NASA September 23, 2002. 40 p. This standard establishes uniform requirements for applying Data Matrix identification symbols to parts used on NASA programs/projects using direct part marking (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, and reading standards. This document addresses 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
