This unit of competency is applicable to trade measurement inspectors appointed under national measurement legislation who may inspect a wide range of pre-packaged products as part of their allocated duties. Compliance with national legislation governing pre-packaged products applies to the accuracy of the labelling information and contents of all items parcelled for sale in all industry sectors.

Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These are found at the end of this unit of competency under the section 'This competency in practice'.

Overview of assessment

Competency must be demonstrated in the ability to perform consistently at the required standard for a wide range of pre-packaged products.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can:

identify, access and apply test procedures

identify and use suitable reference standards

evaluate and adjust the impact of the operating environment on the performance of the instrument

analyse test results to determine the instrument's suitability for verification (trade use)

inspect markings and net contents of pre-packaged articles

identify and implement additional inspection strategies for pre-packaged product related breaches of national measurement legislation

recognise and act on non-compliance

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

report results in the required formats and expected timeframe.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

MSATMINS403A A Inspect a range of trading practices

MSATMINS301A Inspect a range of simple measures

MSATMINS302A Inspect a range of simple measuring instruments

MSATMINS401A Inspect a range of weighing instruments

MSATMINS402A Inspect a range of liquid measuring instruments using volume measures.

Resources may include:

measuring instruments, test equipment and reference standards

computer and relevant software and/or organisation information management system

Certificates of Approval for instruments

relevant legislative and organisational procedures.

Method of assessment

The following assessment methods are suggested:

questions to assess understanding of relevant procedures, trader obligations and remedial actions

review of inspection reports prepared by the candidate

feedback from supervisors and peers regarding the candidate's ability to inspect pre-packaged products in accordance with legislative and organisational procedures

observation of the candidate inspecting pre-packaged products.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. Questioning techniques should suit the language and literacy levels of the candidate.

This competency in practice

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

An inspector is allocated a routine inspection at a factory which packs milk. When reviewing the trader's inspection history, the inspector notices that the trader was issued with an infringement notice 12 months ago for packing 2 L bottles of milk that had an average 4.5% shortfall.On arrival at the premises, the inspector enters the main office and explains the purpose of the visit. While waiting for the site controller to arrive, the inspector assesses the business registration documents on public display and notes they coincide with the pre-inspection documentation he/she retrieved earlier. When the site controller arrives, the inspector explains the purpose of the visit.The site controller provides a site induction and highlights the local workplace health and safety requirements. The inspector then outlines an inspection strategy that will minimise disruption to the trader and suppliers and satisfy the factory's health and hygiene requirements.

The inspector collects the necessary equipment and documentation from his/her vehicle and validates the test equipment before proceeding with the inspection. Given the trader's history, he/she selects an inspection lot of 12 pre-packaged 2 L bottles of milk. On close examination, the inspector finds that the measurement and packer identification markings on this product do not comply with legislative requirements because the 2 L print height is too small.He/she then measures the volume of milk in each bottle and finds an average shortfall of 75 ml or 3.75%. The inspector conducts a detailed investigation of the trader's milk packaging process, measuring instruments, measurement procedure, and their methodology and frequency of measurement tests. He/she finds that the milk density used for setting volumetric fillers is incorrect and causing the shortfall.

Before leaving the premises, the inspector informs the site controller of the non-compliances: i.e. packing pre-packaged products with an average shortfall which exceeded the prescribed performance criteria and a measurement marking print height smaller than the prescribed criteria. He/she outlines the resulting enforcement actions and consequences for failing to correct the non-compliances.

On returning to the office, the inspector files his/her notes, test reports and photographs as evidence of the non-compliance and reports the inspection outcomes in accordance with organisational policy and procedures.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
