21.1. Introduction
The mechanical environmental conditions of the DLoG X 7, DLoG X 10 and DLoG X 12
can vary greatly in terms of vibrations, collisions and shocks.
The matter is made more difficult by the fact that the random values for acceleration and
their frequencies for a given location are often unknown.
It is therefore useful to divide the values into three operation classes (5)M3, (5)M2 and
(5)M1 on the basis of standards, previous measurements and experience.
The following standards offer a practical means of reference:
•
DIN EN 60721-3-5:1997 Classification of environmental conditions, Part 3, Section
5: Ground vehicle installations.
•
Military Standard MIL-STD 810F: 2000.
5M3 Mobile application
Operational environments with high energy vibrations and high energy shocks as well
as rough handling / transport compliant with:
•
Operation class 5M3 according to DIN EN 60721-3-5 or equivalent.
•
Category US Highway Truck according to MIL-STD 810F.
•
Examples: Vehicles without shock absorption: fork lifts, unbalanced machines:
combustion engine of a construction machine.
