Introduction
The mechanical environmental conditions of the DLoG MPC 6 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 5M3, 5M2 and 5M1
on the basis of standards, previous measurements and experience. The following
standards offer a practical means of reference:
•
DIN EN 60721-3-5: 1998 classification of environmental conditions, part 3,
section 5: Use on and in ground vehicles.
•
Military standard MIL-STD 810F: 2000.
(5)M3 Mobile use
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.
