PURPOSE OF THE UNIT STANDARD 
This unit standard is for persons required to prepare flux and for fluxing samples in preparation for fusion. It will apply to laboratory personnel on a precious metal mine. A person credited with this unit standard will be able to:
  • Prepare for fluxing.
  • Flux samples in preparation for fusion. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit calculation is based on the assumption that learners are already competent in terms of the following outcomes or areas of learning when starting to learn towards this unit standard:
  • Science, mathematics and communications at ABET Level 4.
  • Unit standard - Proficiency at determining mass on scale and balance.
  • Relevant Health, safety and environmental standards.
    Proficiency in the use of lifting equipment. 

  • UNIT STANDARD RANGE 
    Specific range statements are provided in the body of the unit standard where they apply to particular specific outcomes or assessment criteria.

    Applicable to the fluxing of material containing any of the precious metals.
