Elements and Performance Criteria

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.
Procedures
All operations are performed in accordance with standard procedures and work instructions
Standard procedures
Standard procedures refer to:
all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards
Properties
Properties include:
particle size, size distribution, particle shape and porosity
flow properties, melt viscosity
rigidity, tensile yield strength, modulus and impact strength
brittle and ductile failure
dimensional and thermal stability
Reinforcements
Reinforcements include:
silicas and clays
glass
fibres
steel
Test methods
Test methods include:
environmental tests - ultra-violet (UV), environmental stress, cracking, weatherometer and chemical resistance
mechanical tests - tensile, creep, coefficient of friction, wear resistance/abrasion and density
chemical/analytical tests
colour tests - colour coordinates (LAB), colour difference ((E)

EVIDENCE GUIDE
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment
The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.
Consistent performance should be demonstrated. In particular look to see that:
knowledge of material properties to the selection of appropriate materials to an application is applied.

Context of and specific resources for assessment
Competence in this unit may be assessed:
by observation of an actual design project where the assessee takes a lead technical role in the material selection
by use of a suitable project where arrangements are made to include the testing aspects.
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.
Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.
Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment
Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
