Special notes

1 Assessment against this unit standard is to be carried out within the context of an organisation operating under a current, valid Rail Licence issued in accordance with the provisions of the Railways Act 2005. The organisation’s operating rules, codes, and instructions, referred to in this unit standard, are those the organisation has in place to meet the requirements of the Rail Licence.

2 Candidates must first hold the appropriate licence, qualification, and/or certification for any electrical work undertaken in the course of assessment for this unit standard. This condition will be in accordance with organisational procedures and/or regulatory requirements that govern live electrical work. Examples include: electrical service technician (A, B), registered electrician.

4 The following Code of Practice applies to this unit standard: NZECP 60:1997, New Zealand Electrical Code of Practice for Inspection, Testing and Certification of Low Voltage A.C. Railway Signalling Control Circuits, Ministry of Commerce, Wellington.

5 Standards relevant to this unit standard may include but are not limited to: AS/NZS 3080:2003: Telecommunications installations – Generic cabling for commercial premises (ISO/IEC 11801:2002, MOD); AS/NZS 3000:2000: Electrical installations (known as the Australian/New Zealand Wiring Rules).

6 Cable types includes copper (all categories), fibre optics, co-axial.

7 Tests and testing may:  be one or two directional, balanced or unbalanced;  be within a building, between sites or between a site and another customer's equipment;  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;  be conducted on 100% coverage, systematic samples, randomly, as part of fault identification or to assess continuity as determined by the organisation.

8 Tests/testing is to be undertaken on at least three occasions, using one or more type of cable.

9 Operations may: be conducted by day or night in all relevant weather conditions; be conducted in restricted spaces or exposed conditions or controlled or open environments; involve exposure to chemicals, dangerous or hazardous substances and movements of equipment, materials and vehicles.

10 Competenz acknowledges the assistance provided by the Transport and Logistics Industry Skills Council in permitting unit of competency TDTB5701A, Perform Cable System Test to be used as the basis for this unit standard.

11 Definitions Cables refer to rail infrastructure designed for the purposes of transmitting signals and communications data. Customer refers to any division or business unit of the entity that owns/manages the railway corridor and corresponding infrastructure; any rail operator that uses the railway corridor; and any other enterprise that leases communications space over given infrastructure to which this unit standard applies.

Organisational procedures refer to documents that include: worksite rules, codes, and practices; equipment operating instructions; technical specifications; non- compliance reports, documented quality management systems; manufacturer’s specifications; and health and safety requirements. Service refers to scheduled data links for/between customers over the given infrastructure.

Please note

Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards.

Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.

Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
