10) This relates to the unit as a whole providing the range of contexts and conditions to which the performance criteria apply. It allows for different work environments and situations that will affect performance. This unit shall be demonstrated in relation to: The relevant State/Territory codes of practice and safe working requirements. Code of practice for the defined interstate rail network. Testing and identifying at least five non-compliant test results. Activities may include procedures for the isolation of cable from supply and/or equipment, and may also include the use of plans and drawings, manufacturer’s / enterprise specifications and manuals. Activities may also include; determining fit for purpose, compliance and functional testing and completing the necessary documentation. Test equipment could include; insulation resistance and continuity tester, multimeter, bell/buzz tester, voltage detector and or daisy chain. Specialised equipment, tools and devices could include cable locator and cable fault tester. Equipment relevant to a particular rail network. Associated hardware could include Trunking, cable pits, conduits and terminals. Cable types may include; copper (all categories) and co-axial Tests may typically address the following items: attenuation, length, balance, noise levels, pair assignment, reversals, short circuits, open circuits, insulation resistance, reflection, signal loss, expected response times, speed, loop resistance Technical report may include: incident report, cable test report, and site survey. Other test devices may also include: TDR (Time Domain Reflectometer), multimeter, tong meter, proprietary devices, oscillator and probe set, bridge megger (computerised), pulse echo, hand held cable testers, spectrum analysers, ohmmeters Generic terms used throughout this Vocational Standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms that apply are given in Volume 2, Section 2.1. |
