scope:

This Standard describes minimum performance criteria for the service braking system, secondary braking system, and parking system for rubber-tired, self-propelled underground mining machines with maximum rated speeds of 32 kph or less and having a rated gross mass of 45 000 kg or less.

In this Standard, "shall" indicates a mandatory requirement; "should" indicates a recommendation, or that which is advised but not mandatory. Notes accompanying clauses do not include mandatory or alternative requirements. The purpose of a note accompanying a clause is to separate from the text explanatory or informative material that is not properly a part of the Standard. Notes to figures and tables are considered to be part of the figure or table and are written as mandatory requirements.

Purpose

To define minimum braking system performance for rubber-tired, self-propelled underground machines.

To provide test criteria by which machine braking system performance may be verified.
