Metrological requirements for hydrogen dispensers for vehicles: adoption of OIML R 139 and revision of NITP 12.1

Overview

The National Measurement Institute (NMI) is seeking feedback on the Australian pattern approval requirements and verification test procedures for hydrogen dispensers for vehicles.

NMI proposes to:

• adopt the latest version of OIML R 139, ‘Compressed gaseous fuel measuring systems for vehicles’, which includes requirements for hydrogen

• revise NITP 12.1, ‘National Instrument Test Procedures for compressed gaseous fuel measuring systems for vehicles’.

Compressed gaseous fuel measuring systems are intended to fuel road vehicles, rail engines, boats, vessels and aircraft with:

• compressed natural gas (CNG)

• compressed gaseous hydrogen

• biogas

• gas blends

• other compressed gaseous fuels.

The OIML Recommendation for instruments of this type was last revised and updated in 2018. NMI’s proposed regulatory approach will support industry development by:

• harmonising Australia’s requirements with international requirements

• removing barriers to trade by aligning requirements with our trading partners and providing a level playing field for manufacturers and suppliers of hydrogen dispensers

• reducing regulatory barriers with all applications for pattern approval assessed against the international standard.

Outcomes

We received one non-confidential submission for this consultation.

Following this consultation, we reviewed Australian pattern approval requirements and verification test procedures for hydrogen dispensers for vehicles.

The following outcomes were implemented on 5 October 2023:

• the 2018 edition of OIML R 139 was adopted as the 2023 edition of NMI R 139 as the pattern approval standard for compressed gaseous fuel measuring systems for vehicles

• the 2023 edition of NMI R 139 replaced the 2011 edition of NMI R 139

• the 2023 edition of NITP 12.1 was determined and replaced the 2016 edition of NITP 12.1.
