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 credited with this standard will be able to read and interpret engineering drawings to be able to select components to be manufactured or assembled. In addition, they would be able to read symbols and understand free hand sketches. The learner will have knowledge of isometric, oblique and orthographic projections, including hidden detail and single plane sectional views. The drawings must conform to international standards.

Learners will be able to:
  • Demonstrate an understanding of engineering drawings and sketches.
  • Explain and apply geometry and scales.
  • Explain the role of isometric and orthographic views in the interpretation of engineering drawings.
  • Discuss and apply concepts related to engineering drawing. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Communication at NQF Level 1.
  • Mathematical Literacy at NQF Level 1. 

  • UNIT STANDARD RANGE 
    The learner is able to refer to engineering drawings, sketches and material lists to access any information necessary to perform his/her duties. The drawings at this level are described as 'basic' in the industry.

    ASSESSMENT CRITERION 2 
    Terms and their symbols/abbreviations are explained in accordance with general industry usage. 

    ASSESSMENT CRITERION 3 
    Drawing definitions are explained to illustrate their role in and impact on engineering drawings. 
    ASSESSMENT CRITERION RANGE 
    These include but are not limited to fit, limit and deviation.
     

    ASSESSMENT CRITERION 4 
    The types of sectional views are contrasted to show the differences between them. 

    ASSESSMENT CRITERION 5 
    The types of dimensions and dimensioning are identified and explained to show the purpose for which they are used. 

    ASSESSMENT CRITERION 6 
    The concept of details and their conventional representation are discussed to illustrate their role in an engineering drawing. 

    ASSESSMENT CRITERION 7 
    The types of tolerances are identified and discussed in terms of their role in engineering drawings. 

    ASSESSMENT CRITERION 8 
    The item represented by the engineering drawing is correctly identified and described in terms of its key features. 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS

    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.
