where relevant, users should access and apply current industry understanding of infection control issued by the National Health and Medical Research Council and State and Territory Departments of Health
Operating environmental impacts
Operating environmental impacts may include:
vibration
wind
heat
dust
electromagnetic interference
out of level
liquid being measured
Records
Records may include:
test reports
safety procedures
a history of equipment calibration and test results
Standard calibrations
Standard calibrations may involve testing and/or calibrating the following equipment and reference materials using standard methods and procedures:
common types of test equipment such as balances, calipers, masses, micrometers, tape measures, rules, temperature (digital) indicating systems, thermometers, timing devices, weighing instruments and volume measures

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 inspector's class reference standards 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 calibration procedures
identify and use high order reference standards of measurement
evaluate and adjust the impact of the operating environment on the results of the calibration
identify the scope of a calibration and compare results with expected outcomes
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:
reference standards, balances, weighing instruments and test equipment
computer and relevant software and/or organisation information management system
National Measurement Institute laboratory operating procedures
relevant legislative and organisational procedures.

Method of assessment
The following assessment methods are suggested:
questions to assess understanding of relevant metrology/calibration terms, principles and procedures
review of calibration reports prepared by the candidate
feedback from supervisors and peers regarding the candidate's ability to verify inspector's class reference standards in accordance with legislative and organisational procedures
observation of the candidate calibrating inspector's class reference standards.
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 customer delivers a 200 L Inspectors Class 1 Volume measure for calibration. Personnel in the laboratory's item reception area log the job and the laboratory supervisor assigns it to a calibration technician. He/she reads the work order and retrieves the approved calibration procedure. The procedure requires the measure to be tested gravimetrically. The technician accesses and validates the test equipment and high order reference standards. The density of the town water supply is determined using a verified hydrometer. The measure is visually inspected for defects and contamination. The volume of the measure is determined three times by filling the measure with town water to the capacity mark, recording the temperature of the water and recording the mass of water. This data is used, in conjunction with the town water density (determined previously) and thermal appropriate expansion/buoyancy corrections, to calculate the actual volume of the measure. The technician notes that some values are outside the allowable tolerance and adjustments will have to be made. He/she takes another set of readings after making the necessary adjustments and records them on the report. The technician applies the required calibration marks to the measure, updates the database, produces a test report and places the item in the despatch area for inspection by the supervisor. The supervisor visually inspects the item and checks the calibration data on the report. The job has taken four hours to complete.
