Description / Abstract:
Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. The purpose of this procedure is to
determine the dynamic stiffness and loss angle (viscoelastic
properties) of elastomeric components used in vehicles when
subjected to forced sinusoidal oscillations in the temperature
range of -50 °C to + 150 °C.
Foreword. The dynamic stiffness and loss angle
characteristics of elastomeric components in the vehicle chassis
are important contributors to vehicle noise and vibration isolation
as well as ride and handling performance.
Applicability. This procedure is appropriate
for the evaluation of all elastomeric components.
