Application
This unit of competency describes the skills and knowledge required to operate a gravity table to clean or process seed. It applies to the operation of gravity tables for cleaning or processing commercial quantities of seed. Workers operate with some judgement and discretion and work would normally be carried out under minimal supervision within enterprise requirements and procedures.
It applies to individuals who take responsibility for their own work and for the quality of the work of others. They use discretion and judgement in the selection, allocation and use of available resources. All work is carried out to comply with workplace procedures.
No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
Elements and Performance Criteria
Element | Performance criteria |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |

The candidate must provide evidence that they can:
assess the product input and outputs of the gravity table
make adjustments to the gravity table settings to maximise the output
set up and prepare gravity table for use
perform basic maintenance of gravity table
report on gravity table operations
disassemble and clean gravity table and associated components after operation
Evidence of Knowledge
The candidate must demonstrate knowledge of:
principles and practices for operating gravity tables
cleaning strategies
deck types and designs and their effects on operational effectiveness
machine capabilities and settings
machinery safety
seed biology and damage to seed by mechanical action
the adjustment and effect of airflow, oscillation and deck angle
the principles of gravity separation
types of available gravity tables
Assessment Conditions
Assessors must satisfy current standards for RTOs.
