Unit Descriptor
Unit descriptor |
This unit of competency covers the ability to apply National Test Procedures to determine whether a liquid measuring instrument using volume measures is suitable for trade and then mark it accordingly. It also involves auditing the performance of verifiers who have previously tested and marked liquid measuring instruments for 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 liquid measuring instruments tested using a volume measure as part of their allocated duties. Liquid measuring instruments are used in a very wide range of commerce. For example, petrol bowsers measure fuel at the point of sale and flowmeters are used to measure bulk commodities such as milk, chemicals and petroleum products during production and distribution. 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
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 any class of liquid measuring instrument listed in the Range Statement. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Assessors should ensure that candidates can:
|
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:
Resources may include:
|
Method of assessment |
The following assessment methods are suggested:
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 arrives unannounced at a medium size service station to check the performance of a number of fuel dispensers. After introducing him/herself to the site manager, the inspector explains the purpose of the visit and asks for the location of the fuel return points. The inspector performs a safety check, completes an AIP form, places safety barriers around the work area and then prepares the test equipment and reference standards. There are seven fuel dispensers with a total of 38 hoses. The inspector tests a selection of dispensers visually. The National Test Procedure requires the inspector to dispense fuel into 15L reference measures and then return the fuel to storage. Approximately 90 litres are dispensed per hose. The inspector finds a number of non-compliances on site. Two hoses are dispensing fuel outside the allowable maximum permissible error, one dispenser has a faulty segment in its display and the lights are not working, the diesel dispenser failed the air elimination test and three hoses are badly worn. The inspector removes the verification mark from all non-compliant dispensers. While testing the fuel dispenser, the inspector notices a number of items displayed for sale outside the office. On closer inspection, some of the pre-packaged items are found not to be marked with a measurement statement. The inspector meets with the site manager to inform him of the non-compliant dispensers. He/she advises the manager not to use any unmarked dispensers, explains how they can be rectified and issues non- compliance notices. They also discuss the non-compliant pre-packaged articles. The inspector takes details for further action, completes the AIP form and fuel usage report and then departs. |
