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 who are assessed as competent against this unit standard will be able to demonstrate competence to sample aggregate materials for standard laboratory testing.

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

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 start their own businesses supplying a construction materials testing service - a process that will accelerate economic transformation and give economic empowerment. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
NQF Level 4 in Literacy and Numeracy competencies. 

UNIT STANDARD RANGE 
Sampling for the following Standard methods of testing road construction materials - TMH 1 (Technical Methods for Highways):
  • Method B1 - The determination of the aggregate crushing value.
  • Method B2 - The determination of the 10 per cent fines aggregate crushing value.
  • Method B3 - The determination of the Flakiness Index of a coarse aggregate.
  • Method B4 - The sieve analysis of aggregates, including the determination of the material passing the 0,425 and 0.075 mm sieves.
