2.3 AS9132 2D STANDARD
This SAE Aerospace Standard (AS) defines uniform Quality and Technical requirements
relative to direct parts marking performed in using Data Matrix symbology. The marking
processes covered by this standard are as follows: Dot Peening, Ink Jet, Laser Etching and
Electro-Chemical Etching.
AS9132 measures and tests various properties like angle of distortion, dot size fill, dot
position and dot ovality on a Pass/Fail basis. When using the AS9132 metrics, each module
is analyzed and graded as “acceptable” or “failure”.
Angle Of Distortion
Angle of distortion measures the angular deviation from 90 degrees axes between rows and
columns of the symbol.
Acceptable value: lower than ±7 degrees.
Dot Size / Cell Fill
Measures and compares the actual dot or cell size to the nominal cell size. No more than 2%
of the elements should be outside this limit. It is calculated according to the specified module
shape (circular or square).
Acceptable value: 60% to 105%.
Dot Center Offset
Measures and compares the actual dot position to the nominal cell position. All elements
should respect this limit. It is calculated only for circular module shape.
Acceptable value: 0 to 20%.
