PURPOSE OF THE UNIT STANDARD 
Learners who demonstrate competence as described in the outcomes of this Unit Standard will understand and be able to apply sampling knowledge and practice in a processing environment. This has application for those individuals in production, laboratory or research and development environments who are required to take samples. It is also relevant to quality assurance.

The qualifying learner is able to:
  • Explain the purpose of sampling and scientific/technical basis upon which sampling is based.
  • Take a variety of samples in a process related environment.
  • Evaluate sampling procedure.
  • Evaluate analysis 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.
