Elements and Performance Criteria

1. Determine information required from tests
   • Analyse relevant documents for any test information requirements
   • Liaise with relevant stakeholders to determine test information requirements
   • Confirm the end use conditions for the refractory
   • Identify discrepancies or conflicts in requirements
   • Negotiate a consistent set of test information requirements
2. Specify required tests
   • Determine data required to yield the required information
   • Determine range of tests and test methods which will yield that data the set of requirements
   • Make a preliminary selection of tests which will provide required data
   • Identify health, safety and environmental (HSE) risks of possible tests
   • Estimate the cost of possible tests
   • Confirm test data will yield information required by stakeholders
   • Specify preferred range of tests and test methods to provide required data
3. Specify sampling regime
   • Identify sample requirements of specified tests
   • Determine sampling frequency required to meet information requirements
   • Draft sampling regime
   • Liaise with relevant stakeholders in relation to sampling regime
   • Negotiate changes to sampling regime and/or information requirements as required.
   • Finalise testing and sampling regime
4. Interpret test data
   • Inspect test data for anomalies or discrepancies and take required action
   • Determine required information from test data
   • Analyse information as required
   • File and report information as required
   • Take appropriate action based on information

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used. Applicable legislation, regulations, standards and codes of practice include: HSE legislation, regulations and codes of practice relevant to the workplace, equipment and production processes and hazardous materials Australian/international standards relevant to the materials being used and products being made any relevant licence and certification requirements. All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence.
HSE and other risks	Identification of HSE and other risks includes consideration of: health and safety risks sustainability risks regulatory risks business risks.

temperature or other cycling

communicate technical information verbally and in writing/drawings

communicate with internal and external stakeholders, including one or more of:

customer representatives

technical experts

regulators

management

refractory designer

refractory installer

identify range of possible test methods from sources, including Standards Australia (SAA), International Organisation for Standardisation (ISO), ASTM International, Joint Support Office (JSO), and Deutsches Institute fur Normung (DIN)

identify range of possible test methods for compression, modulus of rupture, thermal conductivity, density, porosity/permeability, abrasion, thermal expansion and refractoriness

determine optimum sampling and testing regime by evaluating criteria, including:

alignment to technical requirements of the end use

preliminary design calculations

installation, repair or removal issues

cost (e.g. cost of sample and sampling, capital/recurrent costs, and data interpretation)

health, safety and environmental (HSE) risks (e.g. related to sampling, testing equipment and conditions, sample retention and disposal)

relative suitability/costs/risks of possible test methods

inspect and analyse test data to determine required information and take action based on the information

negotiate with relevant stakeholders and document agreed requirements and testing and sampling regime

apply complex and/or theoretical mathematical calculations, statistics, develop/interpret graphs

solve complex problems to determine tests which best deliver the technical requirement at the lowest cost and the least HSE risk.
