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 purpose of the learning is:

Learners who are assessed as competent against this unit standard will be able to demonstrate competence to sample asphalt materials, under supervision, for standard laboratory testing.

This unit standard will enable learners to identify hazards and protective measures during asphalt sampling, identify and prepare resource for sampling, execute sampling, label and transport samples to the laboratory. (under supervision )

The unit standard contributes to the overall competence required of the construction materials tester.

The laboratory test results are used for quality control purposes during the construction and manufacturing processes as well as for final acceptance of the finished products.

Its contribution to socio-economic transformation is that learners would be able to undergo RPL-assessment and thereby receive recognition for previous learning and experience. The employability and career prospects of learners can therefore be enhanced by this qualification.

Previously disadvantaged individuals with this qualification can also progress to the level 4 qualification - this will enable them to start their own businesses supplying a construction materials testing service - a process that will accelerate economic transformation and give economic empowerment.

    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.
