selecting, calibrating, using and maintaining appropriate reference standards in accordance with specified procedures on at least three (3) occasions
maintaining the integrity of reference standards by controlling the operating environment and ensuring that all storage, transport and handling is in accordance with organisational procedures and industry best practice
ensuring that the inspection, maintenance, calibration and documented status of reference standards are completed in accordance with organisational procedures
selecting appropriate reference standards for specific trade measurement activities after careful consideration of the activity’s scope, and expected outcomes and limitations, including the operating environment
validating reference standard suitability against the activity’s scope and expected outcomes in accordance with legislative requirements and organisational policy and procedures
accessing and accurately interpreting reference standard Certificates of Verification, information about tolerances and measurement reports
using the reference standard correctly, including conditioning and applying corrections, as required, to produce consistent and accurate measurements
assessing results of trade measurement activities and analysing any variances from the expected outcomes to identify any isolated or systemic problems linked to the reference standard or its use
using advanced communication and negotiation skills to:
explain the purpose of the trade measurement activities

Must provide evidence that demonstrates knowledge of:
general physical principles and concepts, including weight, mass, gravity, density, volume, length and area
metrological terms, including maximum permissible errors, maximum permissible variations, traceability and uncertainty
Australian legal units of measurement
organisations involved in legal metrology in Australia
hierarchy and classes of reference standards used in legal metrology
purpose of Certificates of Verification issued under the national measurement legislation and the information contained in them
National Measurement Institute (NMI) policy requirements and National Instrument Test Procedures and operating procedures for equipment and reference standards used in job role, including:
transport/storage specifications and procedures for test/specialised equipment and reference standards, and variations requiring approval
maintenance requirements for reference standards and test equipment, including when manufacturer's requirements are unavailable
procedures covering maintenance, recording and reporting faults and calibration
actions to be taken where legal traceability cannot be confirmed
actions to be taken if reference standards and test equipment are found to be defective

calculation steps to give results in appropriate units and precision
maximum permissible errors for instruments under test and tolerances for reference standards
organisational safety procedures and requirements of applicable Commonwealth, state and territory work/occupational health and safety (WHS/OHS) legislation
basic first aid and site safety induction, if required.
Judgement of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event.
This unit of competency should be assessed in the workplace, or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
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.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept in each case).
This unit of competency may be assessed with MSMTM units dealing with the inspection or verification of trade measurement instruments and inspection of trading practices and pre-packaged products.
Holistic assessment methods include:
review of maintenance and calibration records and analysis of results from trade measurement activities prepared by the candidate
feedback from supervisors and peers regarding the candidate's ability to use and maintain reference standards in accordance with legislative and organisational procedures
questions to assess understanding of relevant procedures and specific actions required in response to given reference standard scenarios
observation of the candidate using and/or maintaining reference standards.
Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to:
latest versions of appropriate documentation, such as Certificates of Verification, NMI policy, National Instrument Test Procedures for using reference standards and relevant legislation
equipment manuals, material safety data sheets (MSDS), safety procedures and safety equipment
records, such as test reports, audit reports, instrument history and test results
measuring instruments, test equipment and reference standards
computer and relevant software and/or organisation information management system.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
The assessor must demonstrate both technical competency and currency.
Technical competence can be demonstrated through:
relevant VET or other qualification/Statement of Attainment AND/OR
relevant workplace experience in trade measurement at least to the level being assessed and broad industry knowledge (such as a relevant industry qualification).
Currency can be demonstrated through:
performing the competency being assessed as part of current employment in trade measurement OR
having consulted with trade measurement inspectors and/or verifiers performing the competency being assessed within the last twelve months.
