Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:
inspecting pre-packaged articles on at least three (3) occasions
applying each of the following eight (8) methods for measuring pre-packaged products and identifying short measure:
gravimetric mass method
volumetric method
gravimetric volume method
substitution method
displacement method
mass per unit method
volumetric method for garden landscaping material
frozen fish method
accessing and correctly interpreting documents for the inspection of pre-packaged articles, including national measurement legislation, National Instrument Test Procedures and National Measurement Institute (NMI) inspection policy
ensuring test equipment and reference standards are fit for purpose in accordance with applicable legislation and organisational procedures
planning, preparing for and safely conducting inspections to maximise outcomes and minimise disruption to the public and trader
assessing measurement, unit pricing and packer identification markings on pre-packaged products for compliance with legislative requirements
determining if the net contents of individual pre-packaged products and an inspection lot meet legislative requirements
assessing the effectiveness of the trader's measurement procedure, methodology and test frequency against inspection outcomes
checking compliance and evaluating the performance of measuring instruments using appropriate Certificates of Approval, NMI policy and National Instrument Test Procedures, and adjusting for any impact of the operating environment
reliably determining if measuring instruments are suitable for trade use in accordance with legislative requirements
recognising and acting on non-compliance of trading practices or measuring instruments with national measurement legislation and initiating appropriate enforcement action
