ISO 3450:2011 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.It is applicable to the following earth-moving machinery, operating on work sites or in mining, or travelling on public roads: self-propelled, rubber-tyred earth-moving machines, as defined in ISO 6165; self-propelled rollers and landfill compactors, as defined in ISO 6165 and ISO 8811; self-propelled scrapers, as defined in ISO 7133; remote-control machines, as defined in ISO 6165, wheeled or rubber-tracked; derivative earth-moving machines with rubber tyres; earth-moving machines with rubber tracks and a maximum machine speed greater than or equal to 20 km/h.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 less than 20 km/h (see ISO 10265). While purpose-built underground mining machines are not within the scope of ISO 3450:2011, its provisions can generally be applied to those machines with some braking performance modifications and additions, given in an annex.
