Elements and Performance Criteria

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.

Regulatory framework

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following:

legislative requirements, including work health and safety (WHS)

industry codes of practice and guidelines

environmental regulations and guidelines

Australian and other standards

licence and certification requirements

All operations to which this unit applies are subject to stringent health, safety and environment (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.

Hazards

Hazards include one or more of the following:

equipment failures

industrial (machinery, equipment and product)

noise, rotational equipment or vibration

plant services (steam, condensate and cooling water)

limited head spaces or overhangs

flammability and explosivity

hazardous products and materials

unauthorised personnel

slippery surfaces, spills or leaks

other hazards that might arise

Procedures

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, include one or more of the following:

work instructions

standard operating procedures (SOPs)

safe work method statements (SWMS)

formulas/recipes

temporary instructions

any similar instructions provided for the smooth running of the plant

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:

control sample preparation conditions, including one or more of:

discriminate differences in hue, value and chroma (or colour/tone, lightness/shade and saturation)

recognise colourant addition and colourant dispersion differences

make judgements based on:

acceptability/tolerance

grade 1, 2 or 3 match as required by specification

interpolate and extrapolate data

calculate required adjustments consistent with the colour match data

recommend adjustments that avoid overshooting and minimise the number of adjustments to bring the batch into specification.

Knowledge Evidence

Evidence must be provided that demonstrates knowledge of:

types and application of sample preparation methods, such as:

the impact of sample properties, including surface finish, gloss, thickness, opacity, substrate properties on sample preparation methods and conditions

the effect of a change of light conditions on the appearance of the colour for the pigment combination used as relevant to the product

the impact of opacity on colour as relevant to the product

types and application of colourants relevant to the application.
