DIN EN ISO 3450

Abstract

This International Standard specifies minimum performance requirements and test procedures for the service, secondary and parking brake systems of wheeled and high-speed rubber-tracked earth-moving machines, for the uniform assessment of those brake systems. <br>It is applicable to the following earth-moving machinery, operating on work sites or in mining, or travelling on public roads: <br>&#8212; self-propelled, rubber-tyred earth-moving machines, as defined in ISO 6165; <br>&#8212; self-propelled rollers and landfill compactors, as defined in ISO 6165 and ISO 8811; <br>&#8212; self-propelled scrapers, as defined in ISO 7133; <br>&#8212; remote-control machines, as defined in ISO 6165, wheeled or rubber-tracked; <br>&#8212; derivative earth-moving machines with rubber tyres; <br>&#8212; earth-moving machines with rubber tracks and a maximum machine speed &#8805;20 km/h. <br>It is not applicable to pedestrian-controlled earth-moving machinery (see ISO 17063) or crawler earth-moving machines with steel or rubber tracks that travel at &lt;20 km/h (see ISO 10265). While purpose-built underground mining machines are not within the scope of this International Standard, its provisions can generally be applied to those machines with some braking performance modifications and additions. <br>NOTE At the time of publication, no International Standard dedicated to purpose-built underground mining machines had been developed.
