Scope

This standard specifies the limits of noise power levels and their measurement methods during normal operation of machine tool electrical appliances. This standard applies to electromechanical contactors, motor starters, contactor relays and AC electromagnets with AC 50Hz or 60Hz and rated operating voltage 660V and below. When the electromagnetic system of a single electrical appliance is in a normally closed state, the noise limit value and measurement method are given. This standard does not apply to the limit values and determination of impact noise generated by the closure or release of the electromagnetic system of electrical appliances.
