MEM48033 — Apply chemistry principles to materials used in manufacturing and engineering processes

1 Identify chemical characteristics of materials used in a design or manufacturing process

• 1.1Classify materials used in a design or manufacturing process into elements, organic and inorganic compounds, and mixtures
• 1.2Use chemical formulae to describe design or manufacturing process into elements and compounds
• 1.3Identify the design and manufacturing materials’ atomic structure including sub-atomic particles, charge, atomic number, mass number, and valency
• 1.4Use the periodic table of elements to determine the properties of elements used in the design or manufacturing process from the periodic table of elements

2 Review bonding structure of design or manufacturing process materials

• 2.1Categorise design or manufacturing process materials as metals, polymers, composites and ceramics solids from their structure and properties
• 2.2Relate the physical properties of any design or manufacturing process crystalline and non-crystalline solids materials to the nature of the forces between particles
• 2.3Describe any composites in the design or manufacturing process types in terms of component materials and adhesion and setting processes
• 2.4Describe basic bonding processes for ceramics and glasses in the design or manufacturing process and relate to structure

3 Determine the reactivity of metals and non-metals in the design or manufacturing process

• 3.1Identify the activity of design and manufacturing process materials’ elements and other key properties in terms of their position on the Periodic Table
• 3.2Use first ionisation energy to determine the relative reactivity of metals in a design or manufacturing process

4 Identify the key chemical properties of acids and bases relevant to the in the design or manufacturing process

• 4.1Identify acids and bases relevant to the manufacturing process including relevant salts which form acidic, basic or neutral solutions
• 4.2Identify the pH of relevant acids and bases and classify as either a strong or weak acid or base

5 Analyse chemical reactions relevant to the design or manufacturing process

• 5.1Prepare appropriate balanced chemical equations to describe reactions relevant to the design or manufacturing process using acid-base and electron transfer principles
• 5.2Determine the heat of reaction in relevant chemical reactions
• 5.3Identify the factors affecting reaction rate in the relevant chemical reactions including concentration, surface area, pressure, temperature and catalysis
• 5.4Use the stoichiometry of the reactions to determine the amounts of reactants consumed and products made

What does an assessment tool for MEM48033 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM48033 needs to address all 33 unit components: 5 elements with 16 performance criteria, 6 performance evidence requirements, 11 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 MEM48033?

Auditori pulls the current release of MEM48033 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 MEM48033 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM48033 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 MEM48033, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
