Does the M340 have a seismic rating?

For our PLCs, we used to use a test protocol validated by an expert of vibrations at "Pole Environment L2E" in Grenoble.
It consists in a mono-axial vibration test performed successively for each axis XYZ.
The standard IEC60068-3-3 proposes several test protocols including this mono-axial test in substitution of the bi-axial one
(vibrations applied at the same time on the 2 axis). This test allows us to declare our PRODUCTS withstand MSK64 level 9 (out of 12 levels)
named "destructive level".
