Elements and Performance Criteria

1. Assess and prepare components for required coating process
   • Coating specifications are identified from operation sheets/work procedures.
   • Suitability of pre-treated components for finishing process is checked according to enterprise procedures.
   • Components are prepared as required for finishing application.
   • Components are positioned/located for finishing according to enterprise procedures.
2. Perform simple mixing and estimating operations
   • Mixing ratios are calculated and a range of wet coatings are mixed and thinned as required to standard operating procedures.
   • Required coating quantities are estimated using simple surface area calculations.
3. Perform coating operation
   • Equipment is set up to specification using standard operating procedures.
   • Coating and applied curing technique are monitored to standard operating procedures.
   • Coating application, thickness and colour are checked and maintained for compliance with specifications.

Required Skills

Required skills

Look for evidence that confirms skills in obtaining all relevant drawings specifications andor instructions in accordance with work place procedures racking the components to be coated correctly in accordance with standard operating procedures calculating the correct mixing ratios for given wet coatings accurately where appropriate mixing and thinning the given wet coatings calculating the surface area to be coated correctly where appropriate estimating the quantities of wet coating materials correctly setting up the appropriate coating equipment applying the coating correctly using the appropriate technique curing the coating correctly using the appropriate technique maintaining the coating thickness and colour in accordance with specifications throughout the coating operation checking the coating thickness and colour reading interpreting and following information on written job instructions specifications standard operating procedures charts lists drawings and other applicable reference documents planning and sequencing operations checking and clarifying taskrelated information checking for conformance to specifications performing numerical operations geometry and calculationsformulae within the scope of this unit

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
Overview of assessment	A person who demonstrates competency in this unit must be able to finish work using wet dry and vapour deposition methods Competency in this unit cannot be claimed until all prerequisites have been satisfied
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 finishing work using wet dry and vapour deposition methods 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 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

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.
Coating	Electrostatic powder coating, electrophoretic coating, industrial spray coating and lacquering, electroless (auto catalytic) nickel or copper plating, phosphating, chromating, galvanising, hot tinning, sputter deposition, vacuum evaporation, ion plating, paints, stains and other liquid finishes
Prepared	Visual inspection for contamination, masking out, racking, identification of correct materials to be used, ensuring cleanliness of work area and equipment, operational testing of equipment
Coating operation	Spray application, dip coating
