enterprise quality manual and procedures

Method of assessment

The following assessment methods are suggested

review of documented calibration procedures modified or developed by the candidate and associated validation data

feedback from supervisors andor customers regarding quality of calibration procedures developed or modified by the candidate

observation of the candidate creatingmodifying calibration procedures

oral or written questioning to check underpinning knowledge of complex calibration 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

Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability

Access must be provided to appropriate learning andor assessment support when required

The language literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment

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

Background

Calibration specialists have the skills and knowledge to operate maintain and calibrate a very wide variety of test equipment and measuring instruments with limited guidance They must remain abreast of technical and equipment advances interpret complex technical information accurately and liaise with clients to clarify their needs They must demonstrate high levels of initiative and concentration when performing technically demanding measurements providing solutions for nonconforming work and when adjusting and repairing complex instruments Calibration specialists are often asked to modify existing calibration procedures and develop new ones International and Australian standards specify strict criteria for how this is to be done Above all clients must agree that the procedures meet their requirements and the procedures must be validated before use A considerable understanding of test methods is required and personnel must be able to analyse complex technical specifications and estimate uncertainties

Calibration

The calibration laboratories within the Australian Defence Force have recently been advised that all metric dimensional metrology for example micrometers verniers and dial test indicators must be calibrated to current Australian Standards The supervisor of the physical laboratory conveys the new instruction to his staff One of the technicians is about to begin calibrating a batch of micrometers but because the clients Defence calibration requirements have changed they halt proceedings until a new procedure is drafted The technician rings the other Defence laboratories and establishes that no procedure for that particular model of micrometer exists and therefore seeks permission from the supervisor to develop one The laboratory supervisor has no reservations because the technician is a calibration specialist who has worked in the industry for a long time

The technician first obtains a copy of AS Micrometer calipers for external measurement copies of the technical specifications relating to the reference standards gauge blocks and optical flatsparallels and those for the micrometers themselves The technician lists all the parameters to be tested and drafts a new results template They calculate tolerances and uncertainties amend the template accordingly and neatly lay out raw data calculations and formulae used for peer review As the technician goes through each measurement they record the various steps in accordance with enterprise procedures so that the test can be reproduced The required safety procedures the environmental conditions and the need for equipment stabilisation are also carefully documented

On completion of the test the technician compares the data with the micrometers previous calibration history and double checks the new methodology against a similar American NAVAIR calibration procedure They are satisfied that the procedure is fit for purpose that it meets the clients needs and is technically justified and that the data is valid The technician then presents the draft procedure for another technician to complete

The test is reproduced successfully and the documentation is given to the administration staff for word processing Upon completion the draft test procedure is emailed to the other six Defence laboratories for comment Following the correction of minor clerical errors the procedure is submitted to the militarys primary standard laboratory MSL for final approval and authorisation
