Evidence Required

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

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

It is essential that the process and equipment be understood and that the importance of critical material properties settings and readings is known 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

environmental conditions are correctly interpreted

impact on resin chemistry is understood

appropriate adjustments are made

the reasons for selecting the adjustments are sound

the product meets its required performance

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency

Context of and specific resources for assessment

Assessment will require the adjusting of resin chemistry to meet particular requirements the justification of those changes and making products with the adjusted chemistry

Assessment will occur over a range of situations which will include disruptions to normal smooth operation

Method of assessment

A single assessment event is not appropriate Onthejob assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit

Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency

The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

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

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

Procedures may be written, verbal, computer-based or in some other form, and may include:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant

good operating practice as may be defined by industry codes of practice (e.g. Responsible Care) and government regulations

Resin chemistry

Resin chemistry includes:

process of curing/cross linking of resins

rate of cure and change of properties over cure time

changes in viscosity and other flow properties during progress of cure

final properties of resin post-cure

Environmental changes

Environmental changes may include:

temperature

humidity

air flow/wind

solar/ultraviolet (UV) insolation

Resin composition

Resin composition includes:

resin/catalyst ratio

resin/promoter ratio

resin/catalyst/promoter ratios

changing temperature of resin components (e.g. using chilled catalyst or resin)

ratios of other resin system components

Most appropriate resin composition changes

Most appropriate resin composition changes refers to those resin system changes which:

comply with product requirements

adjust for the current conditions

have greatest ease of use in manufacture

have best financial return

have greatest sustainability contribution

Appropriate action

Appropriate action may include, but is not limited to:

making any required changes to resin composition changes

deferring the fabrication until more suitable conditions prevail

Sustainability

Sustainability incorporates the three aspects of:

survival of the ecology/physical environment – which means that an enterprise needs to manage the impact of the business to ensure the survival of the physical environment

economic viability – efficiency, cost and waste reduction and competitiveness to support survival of the business

social sustainability – an enterprise needs to manage the impact of the business to ensure its continued survival within the community and the survival of the community, including occupational health and safety (OHS)

Alternative process changes

Alternative process changes may include:

controlling the environmental conditions

moving the timing of the job to when conditions are more favourable (e.g. at night)

moving the location of the job to where conditions are more favourable (e.g. in plant, different site and in shade)

Logs and reports

Logs and reports may include:

paper or electronic based

verbal reports

items found which require action

Appropriate action

Appropriate action includes:

determining problems needing action

determining possible fault causes

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility to designated person

Typical problems

Typical problems may include:

unusually hot/cold workplace/weather

extreme humidity

very tight/unusual specification of properties required of product

high/low air flow/wind

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence
