List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Determine job requirements | 1.1 | Follow standard operating procedures (SOPs) |
| 1.2 | Comply with work health and safety (WHS) requirements at all times |
| 1.3 | Use appropriate personal protective equipment (PPE) in accordance with SOPs |
| 1.4 | Identify job requirements from specifications, drawings, job sheets or work instructions |
|
2 | Prepare to develop dye specification and recipe | 2.1 | Confirm specifications and/or sample of textile material product with originator and client |
| 2.2 | Clarify and determine the end use and performance standards expected of finished product with appropriate personnel |
| 2.3 | Analyse sample to determine type and composition using appropriate techniques, as required |
|
3 | Perform preliminary and final tests of dyes | 3.1 | Select dyes and chemicals and auxiliaries with reference to specifications and or previous product dyeing references |
| 3.2 | Identify expected textile production and reproduction processes based on preliminary dye selection, and advise appropriate personnel |
| 3.3 | Determine preliminary dye selection for the sample of textile and trial the preliminary recipe and specifications |
| 3.4 | Select sampling and testing techniques appropriate to evaluation of product during limited production run |
| 3.5 | Perform final selection and evaluation of dyes |
| 3.6 | Comply with environmental requirements and workplace procedures at all stages of the process |
|
4 | Confirm final dye specification and recipe | 4.1 | Seek approval of colour specifications by originator or client prior to production run |
| 4.2 | Test samples from bulk production run using appropriate techniques |
| 4.3 | Analyse results and review, modify and re-test dye, as required |
| 4.4 | Develop, check and file dye specification and recipe in accordance with workplace procedures and industry and quality standards |
| 4.5 | Prepare reports and documentation |
| 4.6 | Monitor dye specification and recipe to ensure continuity and repeatability of colour and test results |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include:
reading and following work instructions, standard operating procedures (SOPs), safe work practices
applying relevant standards
identifying textile characteristics
establishing and confirming criteria for tests
setting up and calibrating test equipment
developing, planning and conducting preliminary trial testing
conducting tests in limited production run against specified quality standards
collating, analysing and interpreting tests
developing and confirming final dye formula and specifications on at least two (2) occasions
testing samples from bulk production run using appropriate techniques
analysing results and reviewing, modifying and re-testing dye, as required
developing, checking and filing dye specification and recipe in accordance with workplace procedures and industry and quality standards
preparing reports and documentation
monitoring dye specification and recipe to ensure continuity and repeatability of colour and test results
complying with environmental requirements and workplace procedures at all stages of the process.
Evidence must be provided that demonstrates knowledge of:
safe work practices and procedures and use of personal protective equipment (PPE)
relevant Australian Standards
fibres, yarns and end products and their properties
dye stuffs and classes
chemistry of dyes and relevance to processing and fastness properties
dyeing processes and dyeing machinery
relation between dye machinery and selection of dye stuffs and classes
tests applicable to the dyeing of textiles
international testing standards
application of dyes in laboratory and production process
work health and safety (WHS) and environmental aspects of relevant workplace activities, including handling of chemicals and dangerous substances
quality criteria
quality practices
workplace procedures
recording and reporting practices.
Assessors must:
satisfy the assessor competency requirements that are in place at the time of the assessment, as set by the VET regulator
have vocational competency in selecting dyes and developing dye specifications and recipe, at least to the level being assessed, with relevant industry knowledge and experience.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
