Specify and interpret refractory tests

Assessment tool

Version 1.0
Issue Date: March 2024


This unit of competency requires the application of knowledge about refractory properties and uses and refractory testing to the acquisition of information about the relevant properties of a refractory. This unit does NOT involve the doing of the tests which is covered by MSAL974005A Perform physical tests or other relevant units in the Laboratory Operations qualifications.

This unit applies to individuals who will be designing a refractory installation or component and may also be monitoring the installation of the refractory. 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. The specification of the testing regime may form part of the refractory specification.

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.

This unit of competency covers the analysis of specifications and possibly contracts to determine what technical information is required, specifying the appropriate testing regime to deliver the required data and then interpreting that data to obtain the required information.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

This unit contains employability skills.




Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

solving problems

communicating at all levels

using organisation knowledge system

analysing

interpreting data

negotiating

technical reporting

Required knowledge

Required knowledge includes:

data produced from all common refractory tests

standard test methods applicable to all common refractory tests

benefits and limitations of test methods and tests

applicability of test data to refractory service

maths and statistics relevant to the tests and test methods

methods of determining information from test data

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
