GB/T 21155-2015 Earth-moving machinery—Machine-mounted audible travel alarms and forward horns—Test methods and performance criteria
Abstract
This standard specifies the static measurement methods and alarm activation requirements for the sound output performance of the driving sound alarm devices and front horns installed on earthmoving machinery as defined in ISO 6165, when operating at work sites and driving on roads. This standard proposes theoretical and performance criteria for practical testing methods.
This standard does not stipulate the installation specifications for one or more driving sound alarm devices or front horns on specific machines, nor does it specify laboratory tests for the functionality and durability of the alarm devices.
This standard applies to alarm devices and horns installed on earthmoving machinery.
