Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to MEM21004A Clean watch and clock components

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

  • following work instructions, standard operating procedures (SOPs) and safe work practices
  • selecting appropriate cleaning methods, processes and equipment appropriate to the work being carried out
  • selecting cleaning solutions appropriate to component, finish, surface coating and material
  • working safely with chemicals and equipment based on information in relevant safety data sheet (SDS)
  • sorting and tracking components during cleaning process
  • cleaning components without damage and verifying components have been effectively cleaned
  • following emergency response procedures, as required.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

  • safe work practices and procedures and use of personal protective equipment (PPE)
  • cleaning solutions and uses
  • cleaning procedures for different components and finishes
  • watch case cleaning methods (ultrasonic and vibrationary)
  • cleaning machine types, uses, function and operation
  • potential for damage to components by chemicals or cleaning operations
  • chemical storage and disposal.

Assessment Conditions

  • Assessors must:
  • have vocational competency in cleaning watch and clock components at least to the level being assessed with relevant industry knowledge and experience
  • satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacementand comply with the National Vocational Education and Training Regulator Act 2011, its replacementor equivalent legislation covering VET regulation in a non-referring state/territory as the case requires
  • Where possible assessment must 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 that reflects 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
  • Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications
  • 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.
