Elements and Performance Criteria

1. Prepare to test rail signalling cable
   • OHS procedures for a given work area are identified, obtained and understood.
   • Established OHS risk control measures and procedures are followed in preparation for the work.
   • Safety hazards that have not previously been identified are noted, and established risk control measures are implemented.
   • Access times and methods are confirmed to comply with customer requirements and relevant legislation
   • Service is checked for availability for testing and is isolated/disconnected from use and carriers network/equipment to ensure no equipment damage can occur during testing
   • Required tests and purpose of tests are identified from site, client documentation and manufacturer specifications
   • Tools and testing devices needed for cable testing are obtained in accordance with established procedures and checked for correct operation and safety
   • Testing devices calibration certification is checked and is current to ensure manufacturers specifications are achieved
2. Test rail signal cables
   • Work area and cable system is made safe for testing and other OHS risk control measures and procedures for carrying out the testing are followed.
   • Tests are set up and performed in accordance with safety measures and manufacturer specifications.
   • Test results are read accurately and compared against manufacturers and site specifications for cable performance
   • Established methods for dealing with unexpected situations are dealt with safely and with the approval of an authorised person
   • Testing is performed efficiently without waste of materials or damage to apparatus and the surrounding environment or services and using sustainable energy practices.
   • Available services are connected and tested for functionality to ensure all previous services have been resumed
3. Report test results
   • OHS work completion risk control measures and procedures are followed.
   • Recommendations on actions needed to maintain cable system integrity resulting from cable tests are made and documented
   • Results of tests are documented accurately and without delay to ensure test results remain current
   • Site and installation files are updated to ensure traceability of information on system performance is maintained, and relevant reports produced

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for this Training Package The Evidence Guide forms an integral part of this unit It must be used in conjunction with all components parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package

Overview of Assessment

Longitudinal competency development approaches to assessment such as Profiling require data to be reliably gathered in a form that can be consistently interpreted over time This approach is best utilised in Apprenticeship programs and reduces assessment intervention It is the industrypreferred model for apprenticeships However where summative or final assessment is used it must include the application of the competency in the normal work environment or at a minimum the application of the competency in a realistically simulated work environment In some circumstances assessment in part or full can occur outside the workplace However it must be in accordance with industry and regulatory policy Methods chosen for a particular assessment will be influenced by various factors These include the extent of the assessment the most effective locations for the assessment activities to take place access to physical resources additional safety measures that may be required and the critical nature of the competencies being assessed The critical safety issues inherent in working with electricity electrical equipment gas or any other hazardous substancematerial present a challenge for those determining competence Sources of evidence need to be rich in nature to minimise error in judgment Activities associated with normal everyday work influence decisions about howhow much the data gathered will contribute to its richness Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practised These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package

Critical aspects of evidence required to demonstrate competency in this unit

Before the critical aspects of evidence are considered all prerequisites must be met Evidence for competence in this unit shall be considered holistically Each Element and associated performance criteria shall be demonstrated on at least two occasions in accordance with the Assessment Guidelines UEE Evidence shall also comprise A representative body of work performance demonstrated within the time frames typically expected of the discipline work function and industrial environment In particular this shall incorporate evidence that shows a candidate is able to Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the performance criteria and range statement Apply sustainable energy principles and practices as specified in the performance criteria and range statement Demonstrate an understanding of the essential knowledge and associated skills as described in this unit It may be required by some jurisdictions that RTOs provide a percentile graded result for the purpose of regulatory or licensing requirements Demonstrate an appropriate level of skills enabling employment Conduct work observing the relevant Anti Discrimination legislation regulations polices and workplace procedures Demonstrated consistent performance across a representative range of contexts from the prescribed items below Perform copper rail signalling cable tests as described in and including Interpreting plans and specifications correctly Testing cable in accordance with workplace procedures Using test equipment and tools correctly and safely Confirming the integrity of a cable system Checking that technicallyoperational specifications are met and that cable is in compliance with specification Following relevant codes of practice procedures and requirements and Completing relevant technical reports records and documentation Dealing with unplanned events by drawing on essential knowledge and skills to provide appropriate solutions incorporated in the holistic assessment with the above listed items Note Successful completion of relevant vendor training may be used to contribute to evidence on which competency is deemed In these cases the alignment of outcomes of vendor training with performance criteria and critical aspects of evidence shall be clearly identified

Context of and specific resources for assessment

This unit should be assessed as it relates to normal work practice using procedures information and resources typical of a workplace This should include OHS policy and work procedures and instructions Suitable work environment facilities equipment and materials to undertake actual work as prescribed by this unit These should be used in the formal learningassessment environment Note Where simulation is considered a suitable strategy for assessment conditions must be authentic and as far as possible reproduce and replicate the workplace and be consistent with the approved industry simulation policy The resources used for assessment should reflect current industry practices in relation to performing cable system tests
