Unit Descriptor

Unit descriptor 

This unit of competency covers developing the specification for installing block or precast refractories and then monitoring that installation to ensure it complies with the specification. It is intended for refractory experts who will most likely also have some management responsibility.

Application of the Unit

Application of the unit 

This unit of competency requires the application of knowledge of refractory installation techniques to ensure the installation meets the requirements of the refractory. It covers the following types of refractory:

  • block
  • brick
  • precast.

This unit does NOT cover the installation of monolithic/castable refractories, refer to PMC557095A Specify and monitor the installation of monolithic /castable refractories . While blocks/precast may also be used to make repairs, this unit may be used to include repairs using these techniques. The specification of the repair technique is covered in PMC557097A Specify and monitor repairs to refractory installations .

This unit applies to individuals who may design a refractory installation and may also monitor the installation of refractory, or they may be installation specialists. They may be working in liaison with other refractory specialists or they may be the sole refractory specialist for this job/in their organisation. They will typically be liaising with a range of other technical experts as well as management and maybe accounts.

This unit may apply to individuals working for an organisation which supplies and installs refractories, is a refractory consulting organisation or a client organisation which buys and uses the refractory.

Evidence Guide


The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Assessment of this unit should include demonstrated competence in a workplace based project or a simulated workplace project.

Access should be available to all normally accessed tables, data etc which would be available to and used by a competent refractory specialist performing this assignment.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Competence must be demonstrated in the ability to select an appropriate material and write the required specification.

Context of and specific resources for assessment 

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment 

  • Assessment must satisfy the endorsed assessment guidelines of the Manufactured Mineral Products Training Package.
  • Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
  • Assessment methods which include direct observation of tasks should also include questioning on underpinning knowledge to ensure its correct interpretation and application.
  • Assessment may be applied under project related conditions (real or simulated) and require evidence of process.
  • Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
  • Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Range Statement


The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
