Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety and environmental requirements must include:

work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for tagging out and isolating machines

environmental requirements, including procedures for trapping, storing and disposing of oils and fluids released from braking systems.

Analytical and evaluative methodology must include:

diagnostic process, sequence, tests and testing equipment.

Tests must include:

accumulator pressure

disc stack height

pressure

system performance with regard to distance and balance

sensor, actuator and wiring harness integrity

sampling collection and processing

wear analysis relating to drums, discs and lining material

analysis of diagnostic systems.
