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 learner credited with this unit standard will be able to determine the volume of product in a tank by performing a tank gauging procedure in accordance with company, national and international standards correctly and safely, thereby establishing the accurate volume of petroleum products in a tank, thus contributing to the stability of the Southern African economy.

This unit standard will contribute to the full development of the learner within the pipeline operations.

The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the Pipeline Transport environment.
