Elements and Performance Criteria

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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Stakeholders
Stakeholders may include:
customer representatives
technical experts
regulators
refractory designer
refractory installer
End use conditions
End use conditions may include:
surface temperature of refractory
required temperature gradient through refractory/outside surface temperature
chemical condition (e.g. pH)
mechanical condition (e.g. impingement)
temperature or other cycling
Types of refractory components
Typical types of refractory components include:
shafts
bearing plates/rings
nozzles and tips
valves and valve seats
crucibles and crucible linings
shelving
Ranking of possible designs
Ranking should be based on:
how well they meet the technical requirements of the end use
HSE risks
HSE risks should include focus on the comparative health, safety and environmental risks of the refractory systems under consideration.
Risks would include risks during:
manufacture
component installation
use
repair
removal and disposal at end of life
Cost of refractory component
Cost of refractory components should be total costs and should include:
material costs
manufacturing cost
installation costs
repair costs
life cycle costs
Optimum refractory component design
The optimum refractory component design would be:
that system which best delivers the technical requirement at the lowest cost and the least HSE risk

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 design an appropriate refractory system 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.
