Application

This unit of competency defines the skills and knowledge required to apply cleaning techniques for watch and clock movements, cases and other components by manual, mechanical and electronic methods, using a range of media.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

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 Identify job requirements from specifications, job sheets or work instructions

2. Apply principles of WHS to cleaning activities

  • 2.1 Select and use appropriate personal protective equipment (PPE) based on information in relevant safety data sheet (SDS)
  • 2.2 Identify hazards associated with cleaning equipment and media
  • 2.3 Follow emergency response procedures

3. Select and prepare appropriate methods, equipment and solutions

  • 3.1 Select cleaning methods, processes and equipment according to type and size of mechanisms, components and cases
  • 3.2 Select cleaning solutions appropriate to component, finish, surface coating and material
  • 3.3 Decant, mix and prepare solutions for use
  • 3.4 Dispose of chemicals according to manufacturer guidelines, legislation and regulations

4. Prepare parts and components for cleaning

  • 4.1 Dismantle watch or clock and component parts to optimise cleaning
  • 4.2 Pre-clean components, as required, for inspection
  • 4.3 Arrange components during machine cleaning to prevent damage
  • 4.4 Arrange and sequence parts and components for cleaning to assist subsequent identification, reassembly and to optimise cleaning

5. Perform cleaning operations

  • 5.1 Set up and operate cleaning equipment using correct and safe work practices
  • 5.2 Monitor and control exposure of components to solutions during cleaning process
  • 5.3 Remove residues, dry and handle cleaned components, as appropriate
  • 5.4 Arrange storage of cleaned components to maintain finish and cleanliness

6. Assess outcomes of cleaning process

  • 6.1 Verify condition of cleaned components and identify remaining residues and contaminants, damage to surface coatings and other component damage
  • 6.2 Account for all components

Assessment Requirements

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 replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or 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.

Foundation Skills

  • text: 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.
