Unit Descriptor
This unit of competency covers the skills and knowledge required to make plugs for composites for routine or one-off production.
Application of the Unit
This unit covers the fundamental techniques for making basic plugs. These are required to fabricate composite products and simple plugs may be made by the composites tradesperson. Plug making may be undertaken by an individual or by a team. It will typically require liaison with a wide range of stakeholders. It would typically be undertaken in a workshop or factory environment and may be used to manufacture new products, prototypes and samples, or to make repairs.
This unit does not cover the making of the plugs which require specialist patternmaking trade skills. See the relevant metals and engineering units of competency for these situations.

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. |

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. |
|
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:
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 fabrication of suitable plugs using appropriate techniques. 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. On-the-job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's 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, 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 |
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. |

|
Appropriate action |
Appropriate action includes:
|
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 |
