Aerospace
industry, automotive industry and medical sectors now-a-days are concerned
about direct marking and traceability issues. Thanks to the highly developed
reading and marking technologies of the present day, the problems inherent to
the conventional and manual marking methods have been solved by the innovative
automated marking technologies. This is why, AS9132 standard is extensively
used for dot peen marking of data matrix codes
People
who are new to AS9132 must be wondering what this phenomenon is all about.
AS9132 is essentially a new UID coding standard which defines the uniformity, quality
and other technical requirements for Dot Peen marking and other metal
components using data matrix symbolism. This AS9132 standard also defines the
standard criteria essential to ensure electronic scanning or reading of the
symbol.
Specific AS9132guidelines with regard to the
direct part marking of aerospace components have been issued by the ATA (Air
Transport Association). These issued guidelines (SPEC 2000, Chapter 9) state
for permanent part identification using bar code technology especially using
data matrix symbols. The main objective is to mark a part with a ‘unique
identifier’ to allow tracking of serialized parts during full life cycle of the
parts and facilitate the use of automated processes in parts handling. Chapter
9 has explicitly mentioned about data content although technical requirements
or quality for Dot Peen and other marking technologies has not been mentioned.
