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 this training package.

Overview of assessment

A holistic approach should be taken to the assessment.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.

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

It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:

select and apply the appropriate laminate to meet the cost and performance specification for the particular job

identify critical materials properties and process variables in relation to the process requirements and the end product

make adjustments to the process as required

identify and take appropriate action on problems and potential problems.

Consistent performance should be demonstrated. For example, look to see that:

the process runs consistently and smoothly, with minimum need for intervention

all safety procedures are always followed.

Assessment method and context

Assessment will occur on special purpose chemical resistant/fire retardant lamination method and equipment and will be undertaken in a work-like environment

Competence in this unit may be assessed:

over a range of actual special purpose lamination methods which are undertaken in the workplace

in a situation allowing the for generation of evidence of the ability to recognise, anticipate and solve problems

using a suitable simulation and/or a range of case studies/scenarios

through a combination of these techniques.

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Specific resources for assessment

This section should be read in conjunction with the Range Statement 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.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

This describes the essential skills and knowledge and their level required for this unit.

Application of knowledge of materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production.

Knowledge and ability to implement organization procedures, quality requirements at each production stage and relevant regulatory requirements, within appropriate time constraints and work standards.

Application of the knowledge of managing risks using the hierarchy of controls applied to the lamination or lay-up processes. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment, operation and cleanup.

Knowledge as a basis for solving process and material problems:

characteristics of materials and behaviour in relation to heat, pressure, flow rate and time

construction of chemical resistant laminates, techniques and equipment used

techniques and equipment used for fire retardant laminates

techniques and equipment used for wet-area applications

applications (eg marine, aerospace, commercial)

changes to materials at various stages of production

impact of variations in raw materials and equipment operation in relation to final product

waste management and importance of non-conforming materials.

Skills to identify and take appropriate action on the range of possible causes of product faults.

Competence also includes the ability to:

plan own work, including predicting consequences and identifying improvements

maintain output and product quality using appropriate instruments, controls, test information and readings

identify and describe won role and role of others involved directly in the process

identify when assistance is required to solve problems.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications, job sheets, procedures, material labels and safety information as provided to technicians.

Writing is required to the level of completing workplace forms.

Numeracy is required, eg to determine quantities required and to interpret corrosion resistance and fire retardance data/tables.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any 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.

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

Context

This unit covers the making of a resistant/retardant laminate in a factory environment on a mould, or the laying up of a composite surface on a substrate such as a tank surface.

This unit covers both the selection of the appropriate resin, matrix and process from the standard systems available from the technician's enterprise, and the making of the resistant/ retardant product. It does not extend to the developing of totally new products using new resin/matrix systems for new (to the enterprise) end use environments. PMB TECH 505 or TECH 601 are more appropriate units in these circumstances.

Procedures

All operations are performed in accordance with procedures.

Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards. These may include:

waterproofing

alkali and acid resistance

heat resistance

fire retardancy

smoke generation

abrasion resistance

AS/NZ standards as applicable

cold weather performance and curing.

Tools and equipment

This competency includes use of equipment and tools such as:

moulds

hand mixing tools such as stirrers

knives and cutters to trim fibres

hand application tools such as rollers, trowels, brushes etc.

relevant personal protective equipment.

Hazards

Typical hazards include:

temperature

hazardous materials

manual handling hazards

equipment operations

working at heights

working in confined spaces.

Problems

'Anticipate and solve problems' means resolve a range of complex, non-routine problems using process and product knowledge to develop solutions to problems which do not have a known solution/s recorded in the procedures.

Typical process and product problems may include:

cracks, dents or imperfections of the mould/substrate

variations in materials, colour, consistency or mix

adjustment and settings of the applicator (where used)

application of the materials to the mould/substrate as required

contamination of materials

equipment malfunctions

pin holes or other imperfections leading to barrier problems.

Appropriate action for problems outside of area of responsibility may be reporting to an appropriate person.

Appropriate action for solving problems within area of responsibility includes asking questions and seeking assistance from appropriate persons/sources.

Variables

Key variables to be monitored include:

surface finish

colour

thickness

product integrity and general conformance to specifications.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
