Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Identify the design requirements for the material

1.1. The engineering requirement for the application is determined from specification or in consultation with others

2. Select metal or alloy for the application

2.1. Material is selected based upon the requirement and consideration of principal properties and further processing

2.2.

3. Consider economic and technical implications of different metals

3.1. Compare possible alternative materials with or without further processing

3.2. Most economic solution is recommended

4. Review final recommendation

4.1. Final recommendation is reviewed with the design team and if required with customers

Evidence Guide

EVIDENCE GUIDE 

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to recommend ferrous and non ferrous metals or alloys for an application. Critical aspects for assessment and evidence are required to demonstrate competency in this unit.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

It is essential that competence is demonstrated in the ability to:

  • Understand the given application and designer's expectations, to recommend the appropriate metal alloy.

Relationship to other units 

This unit may be assessed concurrently with other relevant units.

Assessment method and context 

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the elements, performance criteria, skills and knowledge. A holistic approach should be taken to the assessment.

Assessors should gather sufficient, fair, valid, reliable, authentic and current evidence from a range of sources. Sources of evidence may include direct observation, reports from supervisors, peers and colleagues, project work, samples, organisation records and questioning. Assessment should not require language, literacy or numeracy skills beyond those required for the unit.

The assessee will have access to all techniques, procedures, information, resources and aids which would normally be available in the workplace. The method of assessment should be discussed and agreed with the assessee prior to the commencement of assessment.

Resource implications 

This section should be read in conjunction with the range of variables for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Range Statement

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. 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.

Codes of practice /standards 

Where reference is made to industry codes of practice, and/or Australian/international standards, it is expected the latest version will be used.

Design requirements 

Includes reference to all relevant drawings, specifications, manuals and documentation in accordance with workplace procedures.

Further processing 

Includes addition of alloys and heat treatment ; hardening, tempering, annealing

Materials 

Covers both elemental metals and alloys including:

  • unalloyed steels
  • alloy steels
  • stainless steels
  • grey cast irons
  • white cast irons
