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 prepare to do a product change of a polymer manufacturing process, perform a product change of a polymer manufacturing process, achieve normal process conditions, confirm achievement of product specifications and manage emergency and abnormal conditions. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
Appropriate credits from Textiles Qualification NQF Level 2. 

UNIT STANDARD RANGE 
Applies to the use of acrylics and polyester manufacturing.

In respect of polyester, this apply to processes of paste mixing, monomer manufacturing (or esterification) and polymerisation.

In the area of acrylics, chemical processes such as solvent recovery forms part of the polymerisation process.

The management of the transition from a product to a new product is included here where achieving normal process conditions are achieved.

Tests will not include those concluded in a laboratory.

    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.
