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

identifying and interpreting specifications, charts, lists, drawings and other applicable reference documents for determining mechanical seal requirements

dismantling mechanical seal assemblies used across different sealing applications using appropriate tools, equipment and techniques

examining all component parts for wear and determining the need for repair/replacement and selecting replacement parts according to specifications

reassembling/repairing mechanical seal installations using appropriate tools and equipment

selecting and fitting replacement parts

measuring components to specified tolerances

adjusting mechanical seal tensions and checking for compliance to specifications.

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)

principles of operation of mechanical seals

components and function of a range of mechanical seal designs

installation specifications and procedures

techniques/tools for removing primary sealing elements and secondary seals from mechanical seals

reasons for selection mechanical seal

specified mechanical seal tension

testing mechanical seals

techniques, tools and equipment to measure components.

Assessment Conditions

Assessors must:

have vocational competency in performing installation and removal of mechanical seals 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.

Assessment must occur in a functioning workplace. Where assessment in the workplace would be unsafe, impractical or threatens the environment, assessment must occur in a sufficiently rigorous simulated environment that reflects the circumstances that would be experienced in a functioning workplace. Assessment must cover all aspects of workplace performance, including 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.
