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 
The person credited with this unit standard is able to understand the propagation of ultrasonic sound and the conditions which may affect the effectiveness of the ultrasonic test. Learners will also be able to gather field data in order to inform the remedial actions which will need to be taken. Learners will be able to interpret and use the ultrasonic test report to make informed decisions on what remedial action will need to be taken to ensure the safety of the rail track. Learners will also be able to explain and recommend remedial action to be taken to facilitate repairs.

The qualifying learner is capable of:
  • Demonstrating an understanding of the principles of ultrasonic testing.
  • Gathering field data on the rail.
  • Reading ultrasonic reports.
  • Taking appropriate remedial action. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Learners accessing this unit standard will be assumed competent in:
  • Communication at NQF Level 3 or equivalent.
  • Mathematical Literacy at NQF Level 3 or equivalent.

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Types of remedial action to be taken are explained with an example of each. 
    ASSESSMENT CRITERION RANGE 
    Types of remedial action is determined by the size and type of the defect.
     

    ASSESSMENT CRITERION 2 
    The urgency of the remedial action is determined by the size and type of the defect. 

    ASSESSMENT CRITERION 3

    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.
