UN R67 — 02 series of amendments
Changes from 01 series of amendments (supplement 15)
- What changed
- New paragraph 17.1.6.1. requires that an external inspection of the LPG-container and its accessories, when located outside the vehicle, is possible. It must be possible without the use of tools to dismantle, but with visual aids, according to the specifications of the manufacturer.
- Under paragraph 5.2., the first two digits of the approval number are at present 02, corresponding to the 02 series of amendments.
- New transitional provisions in paragraphs 22.6. to 22.13. use the dates 1 September 2020 and 1 September 2021.
- Why
- One aim of the proposal from the expert from Germany was to improve the specifications for the installation and inspection of LPG-containers and their accessories.
- According to the proposal, corrosion effects (and other damage) appear in normal operation not only on CNG vehicles, but also on LPG vehicles.
- The proposal aims at both adequate protection and sufficient access to the cylinder and its accessories to allow regular visual inspection.
Q1What changed18 changes
External inspection of the LPG-container and its accessories (para. 17.1.6.1.)
New paragraph 17.1.6.1. applies notwithstanding the provisions of paragraph 17.1.6. It says that it must be possible to make an external inspection of the LPG-container and its accessories, when located outside the vehicle. Periodic technical inspection is given as an example. This must be possible according to the specifications of the manufacturer, without the use of tools to dismantle, but with visual aids. Examples of visual aids are lamps, mirrors or endoscopes.
First two digits of the approval number (para. 5.2.)
Paragraph 5.2. now gives 02 as the present first two digits of the approval number, corresponding to the 02 series of amendments. Before, it gave 01, corresponding to the 01 series of amendments which entered into force on 13 November 1999. The first two digits still indicate the series of amendments incorporating the most recent major technical amendments at the time of issue of the approval.
Approval mark examples (Annexes 2A and 2C)
The approval mark examples in Annexes 2A and 2C now show approval number 022439 in place of 012439. The explanations now say that the approval was granted in accordance with the requirements of the Regulation as amended by the 02 series of amendments. Before, they named the 01 series of amendments. The figures of the approval mark examples are changed too.
Type approvals to the 02 series and to the preceding series (paras 22.6. to 22.8.)
Under paragraph 22.6., Contracting Parties applying this Regulation must not refuse to grant or refuse to accept type approvals under the 02 series of amendments. This applies as from the official date of entry into force of the 02 series of amendments. Paragraph 22.7. covers type approvals to the preceding series of amendments, first issued after 1 September 2020. As from 1 September 2020, Contracting Parties applying this Regulation are not obliged to accept these approvals. Paragraph 22.8. covers type approvals to the preceding series of amendments, first issued before 1 September 2020. Until 1 September 2021, Contracting Parties applying this Regulation must accept these approvals.
Type approvals to the preceding series as from 1 September 2021 (paras 22.9. to 22.11.)
Under paragraph 22.9., Contracting Parties applying this Regulation are not obliged to accept type approvals issued to the preceding series of amendments. This applies as from 1 September 2021. Paragraphs 22.10. and 22.11. apply notwithstanding paragraph 22.9. Under paragraph 22.10., Contracting Parties applying the Regulation must continue to accept type approvals of the equipment/parts issued according to the preceding series of amendments. Paragraph 22.11. covers the vehicles/vehicle systems which are not affected by the changes introduced by the 02 series of amendments. For these, Contracting Parties applying this Regulation must continue to accept type approvals issued according to the preceding series of amendments.
Grant of type approvals to any preceding series, and refusal of affected vehicle types (paras 22.12. and 22.13.)
Under paragraph 22.12., Contracting Parties applying this Regulation must not refuse to grant type approvals according to any preceding series of amendments or extensions thereof. Paragraph 22.13. applies as from 1 September 2021. It covers a vehicle type that is affected by the changes introduced by the 02 series but does not meet its requirements. For such a vehicle type, Contracting Parties applying this Regulation may refuse national or regional type-approval and may refuse first registration.
Q2Why it changed
- Proposed by
- Expert from Germany
- Working party
- GRSG, 114th session (April 2018)
Reasons
The expert from Germany proposed a new series of amendments to UN Regulation No. 67. One aim was to improve the specifications for the installation and inspection of LPG-containers and their accessories.
Source
“proposes a new series of amendments to UN Regulation No. 67 to improve the specifications for the Liquefied Petroleum Gas (LPG) multi-valve fitted to vehicles and those for the installation and inspection of LPG-containers and their accessories”
For paragraph 17.1.6.1., the proposal refers to incidents from 2012 where Type-1 cylinders of CNG vehicles of an original equipment manufacturer burst during refilling. Investigations found corrosion effects to be the reason for the burst.
Sources (2)
“From 2012 various incidents occurred where Type-1 cylinders of compressed natural gas (CNG) vehicles (on vehicles of an original equipment manufacturer (OEM)) burst during refilling.”
“Investigations resulted in corrosion effects as the reason for the burst.”
According to the proposal, corrosion effects (and other damage) appear in normal operation not only on CNG vehicles, but also on LPG vehicles. The proposal says that the corrosion effects in the market are similar to those of CNG-cylinders. This is even though UN Regulation No. 67 has no explicit requirement for periodic re-qualification of containers as in UN Regulation No. 110.

“Even though in UN Regulation No. 67 there is no explicit requirement for periodic re-qualification of containers as in UN Regulation No. 110, the corrosion effects in the market are similar compared to those of CNG-cylinders.”
Paragraph 17.1.6. requires that the LPG-system has the best possible protection against damage. According to the proposal, this normally results in housing or other sorts of covering, especially of the cylinders/tanks. These are conditions that stimulate corrosion.

“The LPG-system shall be installed such that is has the best possible protection against damage”
“This normally results in housing or other sorts of covering especially of the cylinders/tanks, conditions stimulating corrosion.”
The proposal aims to meet both the requirement of adequate protection and the guarantee of sufficient access to the cylinder and its accessories. This access is to allow regular visual inspection.
