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:

Prepare damaged product for repairs
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.

The learning for this unit standard is very closely related to the learning for Identify and work with materials for polymer composite fabrication. The two unit standards may be assessed at the same time.

UNIT STANDARD RANGE

The ranges as indicated under the specific outcomes determine the scope and level of this unit standard. Types of repair prepared for include but not restricted to: cracks, gel coat faults, holes, gouges, abrasions and delamination. The preparation process is considered to be level 2 whilst the actual repair is level 3.

All work is performed under supervision.

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.
