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:
  • Fundamental physical reactions,
  • The reactions of light,
  • Fundamental chemical reactions,
  • The rate and mechanism of chemical reactions.

    This unit standard is for anyone who has to apply knowledge of fundamental chemical and physical reactions in the world of work.

    This unit standard will contribute to the full development of the learner 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 manufacturing and processing environment. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:
  • Introductory principles of chemistry and physics.
  • Knowledge about the use and application of the periodic table.
  • Knowledge of fundamental chemical equations. 

  • UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to apply knowledge of fundamental chemical and physical reactions in the world of work.

    The typical context of this unit standard is described in the different range statements listed under the relevant assessment criteria.

    The level assigned to this unit standard is appropriate because the process is moderate in range, established and familiar and offers clear choices of routine responses. The learning demand employs basic operational knowledge and readily available information. The application of this unit standard is to qualify the person for certification in sub-trades.
