In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
People in the field of polymer composite fabrication require the skills, values and knowledge reflected in this unit standard. The fabrication of composites requires the combination of two or more different materials to form a product. What makes composites unique is that a composite material is formed at the same time as the structure itself is being fabricated. This means that the person who is making the structure is creating the properties of the resultant composite material, and so the manufacturing processes that are used have an unusually critical part to play in determining the performance of the resultant structure. Composites are not like metals, where a sheet might be made in one factory and shaped into a car roof in another. With composites it all happens at once. The products are often subjected to considerable or sometimes extreme stress when in operation and the manufacturing process needs to be consistent and accurate.

Qualifying learners are able to:
  • Demould a composite fabrication and prepare it for downstream processes
    The learning outcomes in this unit standard contribute to the exit level outcomes required for the National Certificate in Polymer Composite Fabrication (NQF Level 2) and related qualifications.

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    This unit standard has been designed as part of a progression and reflects the first level of composite fabrication skill. It is one of a series of unit standards for activities at and above this level. The credits assigned to it are based on the assumption that I am learning what is needed for this unit standard as part of my learning for a range of related unit standards. If I have experience in these related activities but do not have credits for them, I can obtain credits by being assessed through a process that recognises prior learning. If I do not have such experience of related activities, then my learning time will be increased. I can choose to be assessed and obtain credits against those other unit standards as I make progress towards the outcomes of this unit standard. 

    UNIT STANDARD RANGE 
    The ranges as indicated under the specific outcomes determine the scope and level of this unit standard.
    All work is performed under supervision.

    Faults and problems are reported and issues relating to the finishing processes are discussed. 
    OUTCOME NOTES 
    Faults and problems are reported and issues relating to the finishing processes are discussed and resolved. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    The assessment criteria have been formulated in this way to provide guidance to assessors:
  • for the purposes of integrated assessment
  • to achieve a balance between performing tasks and understanding
  • to focus on the achievement of the purpose of the unit standard

    Results achieved
    1. A composite product is demoulded and prepared for the next stage

    Indicators
    1. Neither product nor mould is damaged during the finishing processes
    2. Correct demoulding process is followed
    3. Demoulding sequence is determined
    4. All excess material is trimmed from the product in the mould as well as outside the mould as per specifications
    5. Defects are identified and reported
    6. Product is ready for downstream use

    Understanding confirmed
    1. Respond to "what if" and "why" questions covering the effects and consequences of unsatisfactory demoulding from mould
    2. Trimming methods and tools are identified, described and explained
    3. The preparation for downstream use is described and explained in relation to the requirements of the downstream processes and end use

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    My assessment will be governed by the policies and guidelines of the MERSETA Education and Training Quality Assurance BODY, WHICH has jurisdiction over this field of learning. My assessor will be accredited and have a technical qualification in this learning area.
    I can be assessed in the language of my choice although if I have to report incidents or conditions to someone else, I will be assessed on my ability to report in the language commonly used in my working environment.
    I will be assessed in the workplace but I can submit documents, projects, test results and assignments that were not produced in the workplace.
    I can be assessed against this unit standard to obtain credits or as part of an integrated assessment for a qualification.
