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 
A person credited with this unit standard is able to:
  • demonstrate knowledge of milk quality tests,
  • prepare for milk quality tests,
  • determine the quality of raw milk,
  • report on the quality of raw milk in terms of its acceptability for further processing.

    This unit standard is for anyone who has to make a decision on the suitability of raw milk for further processing.

    This unit will contribute to the full development of the learner within the dairy manufacturing environment by providing recognition, further mobility and transportability within the field of manufacturing and assembly. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the dairy manufacturing and processing environment. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:
    Representative sample taking.
    Laboratory tests: Alisarol, temperature, pH, antibiotics, freezing point (or solids-non-fat) and fat content (Gerber). 

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to make a decision on the suitability of raw milk for further processing.

    In the context of this unit standard, The minimum required tests are listed in the range statements. It may, however, be possible for the company to specify certain additional tests to be performed.

    The determination of added water can be done by either the freezing point test or the solids-non-fat test (lactometer-method).

    This unit standard can also be used to assess a person who has to evaluate the acceptability of raw cream in a silo for further processing. In such a case, the relevant site-specific tests must be performed and assessed.

    The level assigned to this unit standard is appropriate because the process requires a range of well-developed skills and offers a significant choice of procedures. Some relevant theoretical knowledge, interpretation of available information, discretion and judgement, as well as a range of known responses to familiar problems are employed. The application of this unit standard is to qualify the person for certification in skilled occupations and sub-trades.

    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.
