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 Mechanical Engineering Fitting (NQF level 4) and related qualifications.

Qualifying learners are able to refurbish machines using equipment and technological aids to achieve close tolerances.

They are able to interpret refurbishment instructions, identify necessary equipment and procedures to be used, diagnose faulty components and overhaul and test them for functioning, making minor modifications where required, and ensure the refurbished machine complies with operational specifications.

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD:

This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
