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:

completing initial verification testing of:

at least one (1) non-automatic weighing instrument from each of the following four classes of instruments (Class 1, 2, 3 and 4); and

at least one (1) catchweighing instrument from either Class Y(a) or Y(b)

accessing and correctly interpreting documentation required for inspections, evaluation of weighing instruments and verifier audits

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

planning, preparing for and safely conducting inspections to maximise outcomes and minimise disruption to the public and trader

checking compliance and evaluating the performance of weighing instruments using appropriate Certificate of Approval, National Measurement Institute (NMI) policy and National Instrument Test Procedures, and adjusting for any impact of the operating environment

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

conducting at least two (2) verifier instrument audits to assess the performance of verifiers who test and mark weighing instruments for trade use

assessing verifier performance against expected outcomes and analysing any variances to identify isolated or systemic problems

identifying potential non-compliance of trading practices (applicable to instruments) with national measurement legislation and initiating an efficient inspection strategy that has a limited impact on others

recognising and acting on non-compliance of a weighing instrument or verifier performance and/or trading practices with national measurement legislation and initiating appropriate enforcement action

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

using advanced communication and negotiation skills to:

explain the inspection 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 inspection

performing specified calculations involving:

fractions, decimals, ratios, proportions and percentages

scientific notation, correct units and the correct number of significant figures

maintaining the security and confidentiality of data in accordance with organisational and regulatory requirements

reporting results in the required formats and expected timeframe

working safely.
