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

A person who demonstrates competency in this unit must be able to perform wire, jig and barrel load/unload work related to non-electrolytic processes.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with performing wire, jig and barrel load/unload work related to non-electrolytic processes or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

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, supervisor's 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

Required skills

Look for evidence that confirms skills in:

correctly loading into the surface finishing machinery

securing and positioning components to minimise damage

securing machine access openings

unloading and stacking components to minimise damage

selecting the correct type and size of wire or rack

planning and sequencing operations

checking and clarifying task related information

checking for conformance to specifications

reading and interpreting routine information on written job instructions, specifications and standard operating procedures. May include drawings

following oral instructions

performing calculations using formulae

Required knowledge

Look for evidence that confirms knowledge of:

the procedures for loading machinery for mass finishing processes

the distribution of the components within the machinery

reasons for distributing the components in a particular manner

the procedures for securing machine access openings

the consequences of not securing machine access openings

the procedures for jigging work for non-electrolytic processes

the precautions to be taken when jigging work for non-electrolytic finishing processes

the appropriate types and sizes of wire or racks used in conjunction with surface finishing using electrolytic processes

different faces to be surface finished/coated

procedures for securing the components to be surface finished using electrolytic processes

procedures for unloading and stacking surface finished components

the damage that can be caused by inappropriate handling and storing of surface finished components

hazard and control measures associated with wiring, jigging and barrel load/unloading work

safe workplace practices and procedures

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.

Non-electrolytic processes

Pre-treatment and finishing processes typical of which are degreasing, de-scaling, surface blasting, flame cleaning, wet blasting, grinding, polishing, wet coating, powder coating, electroplating, anodising, electroless plating, electrophoretic coating and hot dip metallising

Components

Refer to components supplied by the customer

Damaged racks

Damage to plastic coating or contact points

Ensuring good electrical contact

Positioning to facilitate optimum thickness on significant surfaces

Avoidance of gas entrapment

The position of contact marks
