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.
Relevant documents
Relevant documents may include:
specifications
contracts
designs
design briefs
information about refractory failures
other communications from stakeholders
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
Range of tests
Tests to include:
compression
modulus of rupture
thermal conductivity
density
porosity/permeability
abrasion
thermal expansion
refractoriness
Test methods
Test methods include:
Standards Australia (SAA)
International Organisation for Standardisation (ISO)
ASTM International
Joint Support Office (JSO)/Deutsches Institute für Normung (DIN)
Preliminary selection of tests
Preliminary selection should be based on:
how well they meet the technical requirements
HSE risks
HSE risks should include focus on the comparative health, safety and environmental risks of the tests under consideration.
Risks would include risks during:
sampling
testing equipment and conditions
sample retention of required test
disposal of discarded sample and test piece
Cost of test
Cost of materials should be total costs and should include:
cost of sample
cost of sampling
capital and recurrent cost of test
cost of data interpretation
Preferred range of tests and test methods
The preferred range of tests and test methods would be:
those tests which best deliver the technical requirement at the lowest cost and the least HSE risk
Determining information and analysing information
Determining information and analysing information may require:
the undertaking of calculations, drawing of graphs and the application of statistics

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.
