6.3 Vibration levels
When used for its intended purpose, levels of vibration for the
earth-moving machine transmitted from the operator’s seat are
lower than or equal to the tested vibrations for the relative
machinery class in compliance with ISO 7096.
The effective acceleration value for the upper limbs is less than
2.5 m/s². The margin for this value is C m/s² in accordance with
EN 12096:1997.
The effective acceleration value for the body is less than 0.5 m/s².
The margin for this value is D m/s² in accordance with EN
12096:1997.
These values were determined using a representative machine
and measured during the typical operating condition indicated
below according to the measurement procedures that are
defined in the standards ISO 2631/1 and ISO 5349.
