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 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, over a wide range of contexts and / or enterprises, identify a range of safety valves and their application and are able to inspect safety valves, determine faults, assess requirements for repair, and remove, replace and seat parts and components. 

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 machine and equipment maintenance in the engineering area.

The credits allocated to this unit standard assume that a learner has already learned to maintain pipe systems, static seals, and sling loads safely. 

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 autonomously with minimal supervision and according to worksite and manufacturer specifications and occupational safety, health and environmental legislation.

Work is generally, but not exclusively, carried out in a team environment.

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    The 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. The assessor will (at the very least) be accredited and have a technical qualification in this learning area.

    The learner can be assessed in the language of his/her choice although s/he has to report incidents or conditions to someone else. The learner will be assessed on his/her ability to report in the language commonly used in his/her working environment.

    The learner will be assessed in the workplace but s/he can submit documents, projects, test results and assignments that were not produced in the workplace.

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

    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.
