Application

This unit of competency defines the skills and knowledge required to identify and select common engineering materials including ferrous metals, cast irons, carbon and alloy steels, stainless steels, coated steels, nonferrous metals, aluminium and its alloys, copper and its alloys, nickel alloys, zinc, titanium, magnesium, refractory metals, polymers, thermosetting polymers, thermoplastic polymers, ceramics and glasses.
This unit applies to technician level activities in manufacturing and engineering environments. It covers identifying common materials used in engineering by their principal properties. All work is carried out under supervision.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
• identifying common engineering materials
• selecting materials for specific applications on at least two occasions
• verifying selected material as fit for purpose.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:
• common engineering materials
• classification of materials
• structure of materials
• physical properties of materials
• magnetic properties
• optical properties
• mechanical properties
• chemical properties
• materials testing methods including destructive testing and applications
• engineering applications of ferrous metals
• engineering applications of nonferrous metals
• engineering applications of polymers
• effects of mechanical and thermal processes on the properties of materials
• hazards and control measure associated with selecting common engineering materials including housekeeping.

Assessment Conditions

• Assessors must:
• have vocational competency in selecting common engineering materials at least to the level being assessed with relevant industry knowledge and experience
• satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.
• Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
• Conditions for assessment must include access to all tools, equipment, materials and documentation required including relevant workplace procedures, product and manufacturing specifications.
• Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Foundation Skills

• {'skill': 'Foundation Skills', 'description': 'This section describes those language, literacy, numeracy and employment skills that are essential to performance.\nFoundation skills essential to performance are explicit in the performance criteria of this unit of competency.'}
