PURPOSE OF THE UNIT STANDARD |
Learners in the field of engineering require the skills, values and knowledge reflected in this unit standard.
The learning outcomes in this unit standard also contribute to the exit level outcomes required for the National Certificate in Engineering Fitting (NQF level 3) and related qualifications. Qualifying learners are able to identify types of dynamic seals, select for specific use, install and test dynamic seals used in machines and equipment. |
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING |

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. I can be assessed against this unit standard to obtain credits or as part of an integrated assessment for a qualification. |
