This unit of competency covers the ability to apply National Instrument Test Procedures to determine whether a liquid measuring instrument tested using volume measures is suitable for trade and then verified accordingly.

This unit of competency is applicable to verifiers operating under a licence to test and verify specific classes of liquid measuring instruments tested using a volume measure only. Liquid measuring instruments are used in a very wide range of commerce. For example, petrol dispensers measure fuel at the point of sale and flowmeters are used to measure bulk commodities, such as milk, chemicals and petroleum products during production and distribution. The verification tests are performed over extended durations in non-routine and hazardous environments.

Depending on the site, verifiers may be required to meet additional local safety requirements such as basic first aid, confined space entry, working with hazardous materials, working at heights, working with heavy machinery, use of appropriate workplace clearance forms and completing site safety induction.

Under the requirements of Regulation 2.43 of the Trade Measurement Regulations 2009, a servicing licensee or an employee must not verify a measuring instrument relevant to this unit unless they hold a statement of attainment for this unit of competency.

Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:

testing and marking at least three (3) instruments from one (1) or more of the following classes of liquid measuring instruments using volume measures:

fuel dispensers other than liquid petroleum gas (LPG) dispensers

milk flowmeters

flowmeters used for non petroleum products

accessing and correctly interpreting documentation required for verification of liquid measuring instruments

planning, scheduling, preparing for and safely conducting a verification to optimise use of resources and minimise disruption to the public and trader

ensuring test equipment and reference standards are fit for purpose in accordance with applicable legislation and organisational procedures

checking compliance and evaluating the performance of liquid measuring instruments using volume measures using appropriate Certificates of Approval, National Measurement Institute (NMI) policy and National Instrument Test Procedures, and adjusting for any impact of the operating environment and operational factors

reliably determining if liquid measuring instruments are suitable for trade use in accordance with legislative requirements

displaying the verification result on the instrument and completing all verification documentation in accordance with legislative requirements and organisational procedures

identifying and communicating any inadequacies in servicing licensee's organisational procedures and practices that may contribute to non-compliance with legislative requirements

maintaining the accuracy, completeness and currency of statutory records required of servicing licensees such as authorisation, training and relevant licences

test conditions and possible environmental impacts on performance of the instrument

key preparation/measurement steps in test method

calculation steps to give results in appropriate units and precision

maximum permissible errors for liquid measuring instruments under test

safety principles and procedures relevant to liquid measuring instruments

organisational policy and procedures for verifying liquid measuring instruments, including completion of test results, verification documents and statutory records

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:

MSMTMREF301 Use and maintain reference standards

Holistic assessment methods include:

review of test results, verification documentation and verifier statutory records completed by the candidate

feedback from supervisors and peers regarding the candidate's ability to verify the performance of liquid measuring instruments using volume measures in accordance with legislative and organisational procedures

questions to assess understanding of relevant verification procedures, servicing licensee requirements, trader obligations and remedial actions

review of candidate’s responses to verification scenarios, such as potential/actual non-compliances of traders and verifiers, appropriate actions, common issues and problems

observation of the candidate verifying liquid measuring instruments using volume measures.

Access is required to liquid measuring 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 and Approval, NMI policy, National Instrument Test Procedures for verifying liquid measuring instruments and relevant legislation

workplace clearance forms, and correction tables for volume, density and pressure for a range of liquids

equipment manuals, material safety data sheets (MSDS), safety procedures and safety equipment

records, such as test reports, audit reports, instrument history and test results

liquid measuring instruments using volume measures; test equipment, such as pumps, funnels and hoses; 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.

This section describes those language, literacy, numeracy and employment skills that are essential to performance.
