Elements and Performance Criteria

  1. Prepare for verification

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

National Instrument Test Procedures include one or more of:

measurement instrument test procedures

any other test procedure prescribed by the NMI

Classes of liquid measuring instruments using volume measures include one or more of:

fuel dispensers other than LPG dispensers

milk flowmeters tested using a volume measure

or any other liquid measuring instrument prescribed by the NMI

Test equipment includes:

reference standards of measurement

equipment, such as a small measure, dummy nozzle, safety equipment and hand tools

Certificates of Approval include:

any Certificate issued by the Chief Metrologist under Regulation 60 of the National Measurement Regulations approving the pattern of a liquid measuring instrument using volume measures as being suitable for trade

Prescribed performance criteria for liquid measuring instruments include:

that the instrument is of an approved pattern

that the instrument operates within the appropriate limits of error permitted by legislation

that the instrument is used in accordance with any legislative requirements

Verification

Has the same meaning as Section 18GG of the National Measurement Act 1960

Verification marks

Verification marks for different instruments are defined in Sections 2.28 and 2.29 of the National Trade Measurement Regulations

Trading practices include one or more of:

methods used for the sale of goods

using measuring instruments

position of measuring instruments

environmental factors

suitability of instrument

incorrect measurement

Enforcement actions include one or more of:

formal warnings, infringement notices, undertakings, injunction and prosecutions

Legislation includes:

national measurement legislation

applicable Commonwealth, state and territory work/occupational health and safety (WHS/OHS) legislation

NMI policy includes:

test procedure variations between a verification, in-service or audit inspection

bulletins

instructions

determinations

WHS/OHS and environmental management requirements include:

complying with WHS/OHS and environmental management requirements at all times, which may be imposed through state/territory or federal legislation. These requirements must not be compromised at any time

applying standard precautions relating to the potentially hazardous nature of samples

accessing and applying current industry understanding of infection control issued by the National Health and Medical Research Council (NHMRC) and State and Territory Departments of Health, where relevant

Performance Evidence

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

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

identifying and communicating any inadequacies in trader's use of liquid measuring instruments which may contribute to non-compliance with national measurement legislation

demonstrating professionalism and respecting the rights of the trader at all times

using communication and negotiation skills to:

explain the verification purpose, procedures and outcomes to traders, verifiers and managers

inform traders of non-compliances and consequences of failing to rectify them

access external equipment and resources to complete the verification

using numeric skills to perform calculations involving:

fractions, decimals, ratios, proportions and percentages
