Application
This unit involves the skills and knowledge required to test plain rail and field welds using ultrasonic equipment in accordance with rail industry standards, safeworking and regulatory requirements, and workplace procedures. It includes determining test requirements, conducting testing using hand directed equipment, conducting visual examination and measurement of welds, identifying and classifying defects, and completing all required documentation. People achieving competence in this unit will need to fulfil the applicable state/territory legislated rail safety requirements and to comply with relevant codes of practice and/or guidelines. Work is performed under some supervision, generally within a team environment. It involves the application of routine operational principles and procedures when testing rail using ultrasonic equipment, as part of workplace activities across a variety of operational contexts within the Australian rail system. No licensing, legislative or certification requirements apply to this unit at the time of publication. |

Assessment Conditions
As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment. As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment. Assessment must occur in workplace operational situations or, where this is not available, in simulated workplace operational situations that replicate rail corridor workplace conditions. 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. Resources for assessment include: a range of relevant exercises, case studies and/or simulations relevant and appropriate materials, tools, equipment and personal protective equipment currently used in industry applicable documentation including workplace procedures, regulations, rail industry standards, codes of practice and operation manuals. |
