Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Procedures
Procedures may be written, verbal, computer-based or in some other form, and may include:
all work instructions
standard operating procedures
formulas/recipes
batch sheets
temporary instructions
any similar instructions provided for the smooth running of the plant
good operating practice as may be defined by industry codes of practice (e.g. Responsible Care) and government regulations
Joining system
Joining system includes techniques and materials, such as:
bonding (e.g. adhesive, gluing, ethacrylates, sikaflex and epoxy)
using composite materials (e.g. Probond, Divelett, K-Lite and Eurmere)
secondary bonding - cured composite to cured composite
using mechanical fasteners (e.g. bolts and rivets)
Finished application properties
Finished application properties include:
permanent/removable
waterproof/chemical resistant
structural rigidity
strength (tensile, compressive, shear and torsional)
aesthetic
Properties of surfaces to be joined
Properties of surfaces to be joined include:
materials of construction
physical properties (e.g. strength and rigidity)
surface properties (e.g. surface finish and surface treatment/coatings)
size and shape
Preparation of surfaces
Preparation of surfaces to be joined may include:
solvent or other chemical cleaning
chemical etching
mechanical preparation such as blasting, buffing
surface smoothing (e.g. machining)
making of holes or other physical locking features
Most appropriate joining system
Most appropriate system refers to that system which has:
compliance with product requirements
greatest ease of joining
best financial return
greatest sustainability contribution
Sustainability
Sustainability incorporates the three aspects of:
survival of the ecology/physical environment - which means that an enterprise needs to manage the impact of the business to ensure the survival of the physical environment
economic viability - efficiency, cost and waste reduction and competitiveness to support survival of the business
social sustainability - an enterprise needs to manage the impact of the business to ensure its continued survival within the community and the survival of the community, including occupational health and safety (OHS)
Logs and reports
Logs and reports may include:
paper or electronic based
verbal reports
items found which require action
Appropriate action
Appropriate action includes:
determining problems needing action
determining possible fault causes
rectifying problem using appropriate solution within area of responsibility
following through items initiated until final resolution has occurred
reporting problems outside area of responsibility to designated person
Typical problems
Typical problems may include:
incompatible requirements
hazardous materials/preparation methods
non-uniform join
Health, safety and environment (HSE)
All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that the process and equipment be understood and that the importance of critical material properties, settings and readings is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.
Consistent performance should be demonstrated. In particular look to see that:
all reasonably available joining techniques and materials were considered
appropriate techniques and materials have been selected
the reasons for choosing the technique and materials are sound
the product meets its required performance.
Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.
Context of and specific resources for assessment
Assessment will require the selection of joining methods, justifying the selection made and making a number of joints using both mechanical and adhesive joining techniques.
Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.
Method of assessment
A single assessment event is not appropriate. On-the-job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit.
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways, including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
