What an assessment for MEM18083 must cover

44 assessable components: 5 elements (27 performance criteria), 4 performance evidence and 13 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Demonstrate knowledge of global warming and ozone layer depletion

1.1Identify the role of the ozone layer in the earth’s climate and human health
1.2Explain effects of global warming and consequences of ozone layer depletion
1.3Explain role of ozone depleting substances (ODS) and synthetic greenhouse gas (SGG) emissions in global warming

2 Demonstrate knowledge of regulatory requirements in regards to fluorocarbon refrigerants

2.1Explain ARC licence classes and relationship to HVAC/R equipment
2.2Identify requirements to apply for a Refrigerant Handling Licence – Qualified Persons Licence
2.3Explain licence period and procedures to obtain or renew a licence
2.4Explain refrigerant coding and numbering system, including classification for toxicity and flammability
2.5Identify the range of refrigerants covered by ARC licencing
2.6Identify role of ODS and SGG handling licences and trading authorisations in refrigerant handling and disposal
2.7Access information in the Australia and New Zealand Refrigerant Handling Code of Practice relating to specific work tasks

3 Determine job requirements

3.1Identify job requirements from customer order, work specification or other enterprise procedure
3.2Determine if required work includes risk of refrigerant emission
3.3Check refrigerant handling equipment is available and serviceable
3.4Plan work tasks to conform to regulatory requirements

4 Assess equipment and refrigerant status prior to commencement of work

4.1Check refrigerant label on equipment and confirm refrigerant is appropriate for equipment
4.2Adjust work plan to avoid any venting if refrigerant is unable to be positively identified
4.3Identify if refrigerant is flammable and if so check for potential ignition sources and provide appropriate ignition source protection or elimination
4.4Conduct visual check and other tests for gross leaks
4.5Conduct other appropriate leak tests
4.6Adjust work plan to include rectification of leaks

5 Apply regulations, codes and standards to refrigeration and air conditioning work

5.1Apply regulations, codes and standards to installation, servicing, repair or decommissioning of equipment and systems
5.2Establish or maintain appropriate ventilation and temporary flammable zone for equipment with flammable refrigerant
5.3Set and locate gas detectors appropriately for type of equipment
5.4Conduct leak testing according to regulations, codes and standards
5.5Evacuate equipment according to regulations, codes and standards
5.6Charge and recover refrigerants using prescribed methods and equipment
5.7Ensure work on piping, valves and gauges is consistent with regulations, codes and standards

Performance evidence

following work instructions, standard operating procedures (SOPS) and safe work practices
identifying and applying regulations, codes and standards relevant to handling and/or disposal of fluorocarbons in regards to: - removing refrigerant from a self-contained low charge system and store it in an external cylinder - pumping-down refrigerant from a non self-contained low charge system, including: - complying with code limits for receivers - ensuring auxiliary receivers are fitted and suitable - inspecting joints, seals, gaskets and flanges for traces of refrigerant oil and repairing as necessary - leak testing evaporator, heat exchanger, expansion valve, solenoid valve, and other components, including placing low pressure side into positive pressure before testing - using air purgers in negative pressure systems - fitting of gauge isolation valves - mounting compressors, including anti vibration mountings and mufflers - aligning shafts - tensioning compressor drive belts - evacuating a factory matched evaporator and condenser system
identifying coding and classification for at least six: - chlorofluorocarbons (CFCs) - hydrochlorofluorocarbons (HCFCs) - hydrofluorocarbons (HFCs)
identifying flammable refrigerants and taking recommended actions as per fact sheets and Flammable Refrigerants Safety Guide published by The Australian Institute of Refrigeration, Air Conditioning And Heating (AIRAH).

Knowledge evidence

Questions about assessing MEM18083

What does an assessment tool for MEM18083 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM18083 needs to address all 44 unit components: 5 elements with 27 performance criteria, 4 performance evidence requirements, 13 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEM18083?

Auditori pulls the current release of MEM18083 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEM18083 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM18083 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEM18083, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
