Draft Scope/Description:

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.

1.1

This standard provides minimum braking system performance for rubber-tired, self-propelled underground machines, and test criteria by which machine braking system performance may be verified.

Notes:

Additional requirements for brake systems on machines used in coal and gassy underground mines are found in M424.1.

Additional requirements for dynamic and continuous retarding systems are found in M424.4.

1.2

If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

1.3

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but

not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
