PURPOSE OF THE UNIT STANDARD 
This unit standard is for anyone who has to work in refractory construction context and need to understand the fundamental concepts regarding materials and products used within this domain.

A person credited with this unit standard is able to:
  • demonstrate an understanding of the composition of materials and products used in refractory installations or repairs,
  • demonstrate an understanding of the purpose and function of materials or products used in refractory installations or repairs,
  • demonstrate an understanding of material specifications and regulations,
  • demonstrate an understanding of equipment and mechanical aids used during refractory installation and maintenance procedures.

    This unit will contribute to the full development of the learner within the refractory construction environment by providing recognition, further mobility and transportability within the field of construction. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and progression within the construction and civil engineering contexts. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills, knowledge and understanding on:
  • Literacy and numeracy NQF 2,

  • UNIT STANDARD RANGE 
    In the context of this unit standard refractory materials and products refer to bricks/blocks or tiles, ceramic fibres, castables, mouldables, gunite materials, mortars, stainless steel or ceramic anchors.

    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.

    The credit value assigned to this unit standard is appropriate and reflects the average length of time for an average qualifying learning to become competent.

    Recommended contact time and individual learning = 40 h
    Recommended time spent in structured learning in the workplace and assessment = 10h
