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 
Learners who are involved in preparing materials for production in the field of tyre component manufacturing require the skills, values and knowledge reflected in this unit standard.

Qualifying learners can ensure that compounds used for tyre component manufacturing are prepared to the right quality to ensure a smooth production flow. They will understand the importance of having prepared material available when it is required for production and how this is achieved. This will include determining the preparation requirements, carrying out material quality checks, solving common problems and taking the required corrective action.

A learner will be required to demonstrate competence in using both internal mixers and mills to prepare the materials.
The learning outcomes in this unit standard also contribute to the exit level outcomes required for the National Certificate in Tyre and Tyre Component Manufacturing (NQF Level 3) 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. It is one of a series of unit standards for activities below, 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 an integrated learning programme 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.
The learner should be able to work with minimal supervision and according to worksite and manufacturer specifications and occupational safety, health and environmental legislation.
The lay out of machinery and equipment means that the various aspects described in this unit standard require assistance from others and work is carried out in a team environment.

The most common configuration for this process is an internal (Banbury-type) mixer and a twin roll mill. Other variations are possible.
Material preparation includes arranging, handling, checking for expiry date / shelf life, counting, weighing and mixing according to recipe or formula, measuring, cutting to achieve correct mass, preheating, drying, cutting to shape, removing dust, laying out and protecting against damage and contamination where required. 

Specific Outcomes and Assessment Criteria: 

SPECIFIC OUTCOME 1 
Check production schedules, determine compounds to be prepared and advise workgroup members.

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    My assessment will be governed by the policies and guidelines of the MERSETA Education and Training Quality Assuror who has jurisdiction over this field of learning. My assessor will (at the very least) 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.
