Application
This unit of competency covers the ability to calibrate test and measurement equipment in accordance with standard calibration procedures and documented test methods. These procedures/methods specify all associated reference standards, materials, equipment and methods to be used and the required parameters or quantities and ranges to be tested, including the criteria for rejection or approval.
This unit of competency is applicable to laboratory and calibration technicians who carry out tests and/or calibrations using standard calibration methods in first, second and third party laboratories, and laboratories where testing and/or calibration forms part of inspection or product certification. Personnel are not permitted to deviate from explicit instructions in any manner, modify the procedure, nor substitute alternative equipment. They work under limited supervision and results of their work are interpreted and checked by the laboratory supervisor, quality inspector or designated signatory.
While no specific licensing or certification requirements apply to this unit at the time of publication, laboratory operations are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked.

preparing test/calibration documentation that is accurate and complies with requirements
recognising problems or departures in systems and documentation and initiating actions to prevent or minimise them
recognising and reporting opportunities for improvements.
Evidence of Knowledge
Must provide evidence that demonstrates knowledge of:
purpose of metrology and calibration, including common terminology, concepts, principles, procedures and applications
National Association of Testing Authority's (NATA) and National Measurement Institute's (NMI) role in the measurement and testing system in Australia
traceability, including legal requirements for traceability
requirements for the competence of testing and calibration laboratories (e.g. AS ISO/IEC 17025) as they affect job role and responsibilities
hierarchy and appropriate selection of reference materials and instruments
non-conformance/non-compliance procedures and protocols associated with equipment, reference material and calibration procedures
troubleshooting procedures for equipment and test methods
reporting procedures and legislative requirements
handling, transport, storage and operation of reference and working standards
work health and safety (WHS) and laboratory environmental control requirements.
Additional knowledge requirements relevant to the workplace context that apply for different calibration fields must be assessed, including testing and calibration conducted in the following fields:
acoustic and vibration measurement
chemical testing
construction materials testing
electrical testing
heat and temperature measurement
mechanical testing
metrology
non-destructive testing
optics and radiometry
pressure measurement.
Assessment Conditions
Judgement of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event.
This unit of competency is to be assessed in the workplace or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).
This unit of competency may be assessed with:
MSL924001 Process and interpret data
relevant MSL974000 series unit/s of competency
relevant MSL975000 series unit/s of competency
Holistic assessment methods include:
review of calibration results, uncertainty calculations and workplace documentation completed by the candidate
feedback from supervisors and/or customers regarding quality of calibration services provided by the candidate
observation of the candidate performing standard calibrations
oral or written questioning to check required knowledge of standard calibration procedures.
Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to:
specialised calibration/test equipment, reference standards and laboratory facilities
calibration methods, procedures and equipment specifications
workplace quality manual and procedures.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
