In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
The person credited with this unit standard will be able to describe the principles of separating liquids and solids using centrifugal force. They are also able to prepare for and separate liquids using centrifugal force and able to end the separation procedure as well as identify and solve any problems that occur during the separation process.

The qualifying learner will be capable of:
  • Demonstrating an understanding of separating liquids and solids using centrifugal force.
  • Preparing to separate liquids and solids.
  • Separating liquids using centrifugal force.
  • Perform end of separation procedures. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Learners accessing this unit standard will be assumed competent in:
  • Communication at NQF Level 1 or equivalent.
  • Mathematical Literacy at NQF Level 1 or equivalent.
  • General safety in the workplace at NQF Level 1 or equivalent. 

  • UNIT STANDARD RANGE 
    In the context of this unit standard a centrifugal separator refers to a manually or automatically operated centrifugal separator.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
