Earth-moving machinery. Crawler machines. Performance requirements and test procedures for braking systems has-tracked-changes 8 Chemical analysis1 Scope This International Standard specifies minimum performance criteria and test methods to enable uniform assessment of the service, secondary and parking brake systems of crawler machines. It is applicable to self propelled crawler machines, as defined in ISO 6165 including derivative earth moving machines with rubber tracks, with a maximum design speed of 20 km h or less. This International Standard does not cover those machines that are covered
