Unit Descriptor

Unit descriptor 

This unit of competency covers the ability to apply National Test Procedures to determine whether a range of simple measuring instruments are suitable for trade use. The unit also involves auditing the performance of verifiers who have previously tested and marked simple measuring instruments for trade use.

Application of the Unit

Application of the unit 

This unit of competency is applicable to trade measurement inspectors appointed under national measurement legislation who may inspect a wide range of simple measuring instruments as part of their allocated duties. Simple measuring instruments are used in a very wide range of commerce. For example, dip sticks are used to measure bulk petroleum products and beverages, dimensional measuring instruments are used to measure the cubic measurements of packages for freight and length/area instruments are used to accurately measure a wide range of articles sold by reference to those measurements.

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 any class of simple measuring instruments listed in the Range Statement.

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)
  • identify the scope of a verifier performance audit and assess results with expected outcomes
  • audit the performance of verifiers of simple measuring instruments
  • identify and implement additional inspection strategies for non-instrument 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:

  • MSATMREF301A Use and maintain reference standards.

Resources may include:

  • simple 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, licensing requirements, trader obligations and remedial actions
  • review of inspection reports and verifier performance audit reports prepared by the candidate
  • feedback from supervisors and peers regarding the candidate's ability to verify the performance of instruments in accordance with legislative and organisational procedures
  • observation of the candidate conducting an inspection.

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 has been allocated the task of verifying an area measuring instrument at a tannery. In preparation for his/her visit, the inspector accesses the organisation's database to establish the instrument type, site contact details and any previous history for the instrument or trader. The inspector assembles the test equipment required for the inspection. All reference standards are inspected for damage and validity against their certificate prior to them being stowed with the other equipment safely in the vehicle. On arrival at the tannery, the inspector introduces him/herself to the manager and explains the purpose of the visit and the process involved. During this discussion, the inspector explains that he/she will inspect the area measuring instrument for compliance with its Certificate of Approval, assess the operating environment for factors that may impact on its performance and conduct visual and performance tests in accordance with the National Test Procedure. If the instrument complies with these requirements it will be marked as being acceptable for trade use. During the subsequent inspection, the area instrument is found to have a capacity greater than what is stated in the Certificate of Approval and the instrument's performance exceeds the maximum permissible error stated in the national measurement regulations. Consequently, the inspector removes the previous verification mark from the instrument and issues the trader with a warning that the instrument cannot be used for trade until it has been corrected and verified again. Before leaving the premises, the inspector provides the trader with some options for rectifying the non-compliances and gives the manager an opportunity to ask any questions about trade measurement activities.
