Application
This unit of competency defines the skills and knowledge required to prepare by abrasive or chemical means, a composite surface prior to bonding/joining or coating and includes the preparation of composite surfaces and other surfaces which are used in conjunction with composites (e.g. metal surfaces).
This unit complements unit MEM26016 Select and use joining techniques.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: A
Unit Weight: 4

This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range Statement
This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. | |
Most appropriate substrate preparation includes the following: | compliance with product requirements greatest ease of preparation best financial return greatest sustainability contribution |
Areas for improvement include one (1) or more of the following: | incompatible surface applications with substrates non-uniform substrate preparation the use of hazardous materials |
Sustainability includes the following: | survival of the ecology/physical environment economic viability social sustainability |
