Unit Descriptor

Unit descriptor 

This unit of competency covers the ability to apply National Test Procedures to determine whether a simple measuring instrument is suitable for trade and then mark it accordingly. It also involves the installation and/or repair of simple measuring instruments.

Application of the Unit

Application of the unit 

This unit of competency is applicable to verifiers who operate under a licence to test and mark a specific class of simple measuring instruments. 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 determine cubic measurements of packages for freight and length/area instruments are used to 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'.

Evidence Guide


The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Competency must be demonstrated in the ability to perform consistently at the required standard for one 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
  • install and repair measuring instruments to meet statutory requirements
  • 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)
  • 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 simple measuring instruments
  • relevant legislative and organisational procedures.

Method of assessment 

The following assessment methods are suggested:

  • questions to assess understanding of relevant procedures and remedial actions
  • review of verification 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.

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.

A local hotel tests their spirit measuring instruments once a month to ensure they comply with the relevant trade measurement legislation. These tests reveal two of the remote storage spirit measuring instruments are giving short measure to their customers. The publican contacts a verifier, explains the situation and asks if he/she can repair them today. When the verifier asks the publican if he is still using the instruments, he responds 'yes'. The verifier advises the publican that he should immediately stop using the two instruments to avoid being fined for using an incorrect instrument by national Trade Measurement.The verifier arrives that afternoon and discusses the problem in more detail with the publican. During this discussion, the verifier explains what he/she will be doing and confirms that he will maintain the highest standards of hygiene when working with the spirits.The verifier conducts a preliminary test on the incorrect instruments and confirms the publican's results. After making adjustments to rectify their inaccuracy, the verifier assesses the instruments design against the Certificate of Approval and completes a full test in accordance with the nationally recognised National Test Procedures. As all results are now within the maximum permissible errors, the verifier marks the instruments with a certification mark and completes a certification form. Before leaving the hotel, the verifier explains to the publican that he/she has completed the work and is now leaving the hotel. The verifier submits the relevant forms to national Trade Measurement within the specified 14 days.
