Zero Emissions Technology

Bus and Coach Safety Advisories

The BIC is developing a Series of 3 Bus & Coach Safety Advisories for Zero Emissions Technology as part of the Heavy Vehicle Safety Initiative Funding Agreement, administered by the National Heavy Vehicle Regulator (NHVR).

The Series aims to provide information relating to heavy vehicle standards and specifications, safe vehicle operations, vehicle maintenance, and infrastructure. The Series is primarily written for the manufacturers, suppliers and operators of heavy vehicles and related components and infrastructure. Information provided in this Series may also be a useful reference for Australian state and territory governments, transport agencies and transport regulators.

Advisory 1 of this Bus and Coach Safety Advisory Series was released in August 2023 and is intended to support incoming ADR’s 109/00 and 110/00 relating to zero emissions technology for heavy vehicles.

Below are relevant regulation and standards resources that can be incorporated into existing heavy vehicle specification forms (systems) for use by manufacturers, bus operators and transport agencies.

Chapter overview

  1. Componentry of battery and hydrogen zero emissions vehicles
  2. Heavy vehicle regulations in Australia and ADR’s.
  3. Recommendations for the adoption of United Nations regulations and website links to the latest regulations:
    1. UN R100 Rev. 3 – Uniform provisions concerning the approval of vehicles with regard to specific requirements for the electric power train.
    2. UN R10 Rev. 6 – Electromagnetic compatibility
    3. UN R134 – Uniform provisions concerning the approval of motor vehicles and their components with regard to the safety-related performance of hydrogen-fuelled vehicles (HFCV)
    4. EC 79/2009 – Uniform provisions concerning the approval of motor vehicles and their components with regard to the safety-related performance of hydrogen-fuelled vehicles (Note: as a base as R134 does not require all components subject to high pressure hydrogen to be tested and certified)
    5. UNR138 Rev. 1 – Uniform provisions concerning the approval of Quiet Road Transport Vehicles with regard to their reduced audibility (QRTV).
  1. Review of other related or equivalent international standards and specifications.
  2. Future global technical specification – Global Technical Regulation 20 on electric vehicle safety.
