Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Determine job requirements |
1.1. Work requirements are determined from job sheet, instructions or other specifications in accordance with standard operating procedures. 1.2. Appropriate coating system and material is selected to meet job specification. 1.3. Appropriate coating process and equipment is selected to meet job specification. 1.4. Work site is prepared for surface coating activities. |
2. Work piece prepared for application of protective coating |
2.1. Surface condition is inspected for readiness for application of protective coating according to specification. 2.2. Unsuitable work pieces/surfaces and fabrication defects are identified and appropriate remedial action or reporting is undertaken in accordance with standard operating procedures. 2.3. Components are masked where protective coating application is not specified. 2.4. Conditions for overspray are identified. |
3. Equipment is prepared for application of surface coating materials |
3.1. Required plant and equipment basic operations are understood. 3.2. Routine maintenance is undertaken on plant and equipment in accordance with standard operating procedures. 3.3. Status/reports are recorded by proforma or orally in accordance with standard operating procedures. 3.4. Coating application equipment is assembled in accordance with equipment requirements and standard operating procedures. 3.5. Personal protective equipment is selected and maintained in accordance with manufacturers' specifications and standard operating procedures. |
4. Apply coatings using conventional, airless and plural component equipment |
4.1. Coating product type, solvent, uses, mixing procedure, clean-up and safety requirements are identified as appropriate. 4.2. Correct method of determining wet film thickness in accordance with specified dry film is demonstrated. 4.3. Coating material is thinned to suit the application method and to achieve required film thickness. 4.4. Coating is applied using specified application method and standard operating procedures. 4.5. Coating application and curing technique is monitored according to standard operating procedures. |
5. Clean and store equipment |
5.1. Coating application equipment is cleaned, disassembled and inspected for damage. 5.2. Faulty equipment is recorded and reported to appropriate personnel in accordance with standard operating procedures. 5.3. Coating application equipment is stored in accordance with standard operating procedures. |
6. Inspect finished surface |
6.1. Surface finish is assessed for profile size differences and uses. 6.2. Coating thickness is determined using appropriate instruments and results are compared with job specifications. 6.3. Total surface is inspected for conformance to specification in accordance with standard operating procedures. 6.4. Inspection results are recorded and reported in accordance with standard operating procedures. |
7. Calculate, estimate and cost application of protective coating |
7.1. Surface area of work piece, materials, labour and equipment are assessed. 7.2. Cost of materials, labour, handling and equipment are determined. 7.3. Results are recorded and reported as an estimate for the application of a protective coating system. |

Evidence Guide
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 |
A person who demonstrates competency in this unit must be able to apply protective coatings (advanced). 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 applying protective coatings (advanced) 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 |
Range Statement
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. |
