This unit involves the skills and knowledge required to calibrate volumetric measuring devices and gas analysers used in the measurement of gas quality.

It includes inspecting, validating, calibrating and recommissioning of custody transfer devices and gas quality measuring equipment in accordance with reference industry standards to meet contractual, organisational or statutory requirements.

This unit applies to any safe work site where gas industry operations occur. It also applies, where applicable, to other workplaces in the electricity supply industry (transmission and distribution and generation), the electrotechnology industry and the water industry, subject to all work health and safety (WHS)/occupational health and safety (OHS)and duty of care requirements being met for the workplace.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
