Perform complex tests to measure engineering properties of materials


Application

This unit of competency describes the skills and knowledge to prepare test specimens and perform multi-stage mechanical tests on them. The unit requires personnel to create test conditions that suit the materials intended use, optimise measurement procedures and recognise critical measurement points during the tests. The unit also covers data analysis and troubleshooting procedures/equipment that have led to atypical data or results.

This unit applies to laboratory personnel in the construction materials, mining and manufacturing industry sectors.

No licensing or certification requirements exist at the time of publication. However, regulations and/or external accreditation requirements for laboratory operations exist, so local requirements should be checked. Relevant legislation, industry standards and codes of practice within Australia must also be applied.


Elements and Performance Criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1

Interpret and schedule test requirements

1.1

Review test request and sample documentation to identify required test parameters and intended use of bulk material

1.2

Identify hazards and workplace control measures associated with the sample, preparation/testing methods and equipment

1.3

Inspect samples, compare with specifications, record and report discrepancies

1.4

Liaise with client when samples and/or request forms do not comply with workplace procedures

1.5

Match required parameters with suitable test methods, available equipment and instrument specifications

1.6

Plan parallel work sequences to optimise throughput of multiple sets of samples

2

Prepare and measure test specimens

2.1

Prepare test specimens in accordance with test method

5

Process and analyse data

5.1

Confirm data is the result of valid measurements

5.2

Perform required calculations and ensure results are consistent with estimations and expectations

5.3

Record results with the appropriate accuracy, precision and units

5.4

Estimate and document uncertainty of measurement in accordance with workplace procedures, if required

5.5

Analyse trends in data and/or results and report out-of-specification or atypical results promptly to appropriate personnel

5.6

Troubleshoot procedure or equipment problems which have led to atypical data or results

6

Maintain laboratory records

6.1

Make entries on report forms or into a laboratory information management system accurately calculating, recording or transcribing data as required

6.2

Ensure traceability of sample from receipt to reporting of results

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance.

Numeracy skills to:

calculate and determine required engineering properties with appropriate accuracy, precision and units (such as total and effective stress, strain and pressure)

use calibration charts.

Other foundation skills essential to performance are explicit in the performance criteria of this unit.
