Density Measurement in the Retail Sale of Liquefied Petroleum Gas

Closed 16 Dec 2016

Opened 10 Nov 2016


The purpose of this discussion paper is to commence a review of the current requirements relating to the measurement of Liquefied Petroleum Gas (LPG) density when supplied for retail sale. More specifically, this paper is intended to seek stakeholder submissions regarding current pattern approval requirements for LPG dispensers relating to the measurement of LPG density.

The discussion paper provides an overview of the current requirements and requests stakeholder submissions regarding possible amendments and improvements to these requirements. In support of such amendments, the discussion paper also seeks stakeholder proposals regarding innovative or alternative methods for measuring LPG density which would reduce the overall regulatory burden on Australian industry while continuing to ensure fair and equitable measure in the retail sale of LPG.

Why We Are Consulting

The National Measurement Institute (NMI) is responsible for the administration of the national trade measurement system. Key elements of this system are the pattern approval and verification of measuring instruments used for trade, including LPG dispensers.

NMI has recently received submissions from a number of stakeholders regarding the issue of density measurement in the retail sale of LPG.

NMI is committed to being a responsive, responsible and best-practice regulator. As such, we recognise the importance of reviewing our requirements over time to ensure that they are still achieving the intended objective and are providing an overall benefit to Australian industry and the wider community.

NMI welcomes all stakeholder submissions regarding the current requirements for LPG dispensers as they relate to the measurement of LPG density.
