Application

This unit of competency defines the skills and knowledge required to safely remove and replace a range of fluid conveying components and assemblies, and inspect/test fluid conveying assemblies.

It applies to repairs and replacement to pressure and suction systems on fixed and mobile plant/equipment, including marine, heavy plant and manufacturing plant applications with system pressures range of 10.5 MPa to 35 MPa, ranging up to 70 MPa.

Where interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.

Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.

This unit should not be selected when unit MEM18055 Dismantle, replace and assemble engineering components or unit MEM27017 Maintain, fault find and rectify hydraulic systems for mobile plant has already been selected.

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

What You'll Learn

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

identifying and interpreting specifications and obtaining relevant data with respect to connecting and disconnecting fluid conveying system components

identifying potential hazardous situations and carrying out a risk assessment and isolating, tagging, locking off and displaying signage using appropriate procedures

locating faulty component, neutralising pressures and disconnecting and removing fluid conveying components and assemblies using appropriate techniques, tools and equipment and sealing open system with appropriate sealing materials

selecting replacement components from manufacturer catalogues and other reference sources

performing pressure testing on fluid conveying assemblies and individual components using fluid power principles and undertaking condition and serviceability assessment and storing components/assemblies according to industry standards

connecting components and assemblies to equipment, removing tagged out equipment, signage and safety blocking devices

testing equipment and fluid conveying systems using appropriate test equipment and rigs for compliance to manufacturer and industry standards

completing routine reports and certification procedures.

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)

different sources of stored energy and their applications

work health and safety (WHS) responsibilities of customer and self

safety/security lock-off devices and signage and procedures and reasons for installing lock-off devices and signage

basic functions of fluid power systems, including:

effects of heat and contamination

pressures

flow rates and temperatures

hose strength and size

effect of media on hoses

test

operational and burst pressures

techniques and safety practices for pressure testing

tools, techniques and procedures for removal of components

troubleshooting techniques

standard and specific sealing materials and techniques

different fluid conveying parts and their function

techniques and safety practices for pressure testing

criteria for assessment

methods of cleaning, sealing and storage

techniques and criteria for connection and confirming connection

techniques, procedures and safety practices. including neutralisation of pressures.

Assessment Conditions

Assessors must:

have vocational competency in connecting and disconnecting fluid conveying system 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.
