AS ISO 9533:2020 Earth-moving machinery一Machine- mounted audible travel alarms and forward horns一Test methods and performance criteria. AS ISO 9533 specifies a static method for determining the sound output performance and alarm activation requirements of audible travel alarms and forward horns mounted on earth- moving machinery, as defined in ISO 6165, for operation on work sites and travelling on public roads. It offers objective test methodologies and performance criteria. It is applicable only to those alarms and horns that are installed on the earth-moving machinery. It does not specify the installation of one or more audible travel alarms or forward horns on particular machines. It addresses neither the laboratory testing of warning alarm functionality nor durability. NOTE Earth-moving machine manufacturer’s practices, worksite requirements and local, national or regional regulations could require the fitting of the alarms or horns specified in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
