Elements and Performance Criteria

  1. Maintain reference standard integrity

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:

measuring instrument test procedures

article measurement procedures

any other test procedure prescribed by the NMI

Regulatory requirements include:

Regulation 13 Certificates on each reference standard

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 required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria, and include demonstration of:

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

access external equipment and resources to complete the activity

explain procedures and expected outcomes of activities to traders and managers

organise large reference standards to be dispatched ahead of visit to trader's premises

performing specified calculations involving:

fractions, decimals, ratios, proportions and percentages

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

interpretation of statistical quantities, such as mean, median, mode, range, variance and standard deviation

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.

Knowledge Evidence

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
