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 
Learners who demonstrate competence as described in the outcomes of this unit standard will be able to monitor and control product parameters in a processing environment.

The qualifying learner is able to:
  • Demonstrate an understanding of monitoring product parameters in a processing environment.
  • Assess product suitability by means of measurements, checks and simple tests.
  • Plot values and compare these values against maximum/minimum control limits.
  • Take corrective action to address non conforming results. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Learners accessing this unit standard will have demonstrated competence against mathematical literacy and literacy at NQF Level 1 or equivalent. 

    UNIT STANDARD RANGE 
    The typical context of this unit standard includes any processing environment, for example chemical-, minerals- or beverage processing.

    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.
