UN R95 Supplement 1 (04 series) · UNECE Regulation No. 95 (ECE R95) — Uniform provisions concerning the approval of vehicles with regard to the protection of the occupants, fuel system integrity and protection against electrical shock in the event of a lateral collision.
UN R95 — Supplement 1 to the 04 series of amendments
Base text → Supplement 1
- What changed
- This Regulation now also applies to some M1 vehicles with a maximum permissible mass exceeding 3,500 kg.
- These are vehicles where the "R" point of the lowest seat is not more than 700 mm from ground level. The height is taken with the vehicle in the condition corresponding to the reference mass defined in paragraph 2.10.
- As before, the scope also covers M1 vehicles with a maximum permissible mass not exceeding 3,500 kg, and N1 vehicles.
- Why
- The large majority of M1 vehicles, regardless of their mass, may have post-crash electric shock and fuel leakage risks.
- The aim is that vehicles such as large sedans, saloons, and some heavy sport utility vehicles can be properly type-approved as in the past.
- The proposal also recognises the specific conditions of heavy M1 vehicles with a high seating position.
Q1What changed2 changes
Scope extended to some M1 vehicles over 3,500 kg (para. 1.)
This Regulation now also applies to some M1 vehicles with a maximum permissible mass exceeding 3,500 kg. These are vehicles where the "R" point of the lowest seat is not more than 700 mm from ground level. The height is taken with the vehicle in the condition corresponding to the reference mass defined in paragraph 2.10. Before this supplement, the scope covered M1 vehicles with a maximum permissible mass not exceeding 3,500 kg, and N1 vehicles.
Updated web address in the R.E.3. footnote
The footnote that refers to the Consolidated Resolution on the Construction of Vehicles (R.E.3.) has a new web address. It now gives www.unece.org/transport/standards/transport/vehicle-regulations-wp29/resolutions instead of www.unece.org/trans/main/wp29/wp29wgs/wp29gen/wp29resolutions.html.
Q2Why it changed
- Proposed by
- Experts from Japan and the International Organization of Motor Vehicle Manufacturers
- Working party
- GRSP, 69th session (May 2021)
Reasons
When WP.29 adopted ECE/TRANS/WP.29/2020/61 at its 181st session, the scope of UN Regulation No. 95 was amended. The derogation for vehicles with a high R-point was deleted, and a mass restriction to M1 vehicles was introduced.
Sources (2)
“Due to the adoption of the document submitted by GRSP (ECE/TRANS/WP.29/2020/61) at the 181st session of WP.29”
“the scope of UN Regulation No. 95 was consequently amended by deleting the derogation for vehicles with a high R-point and by introducing a mass restriction to M1 vehicles”
The large majority of M1 vehicles, regardless of their mass, may have post-crash electric shock and fuel leakage risks. They may also have possibilities of occupant injuries due to lateral impacts by other vehicles. So it should be possible to delete this mass restriction. The aim is that vehicles such as large sedans, saloons, and some heavy sport utility vehicles can be properly type-approved as in the past.

“Considering that the large majority of M1 vehicles, regardless of their mass, may have post-crash electric shock and fuel leakage risks, as well as possibilities of occupant injuries due to lateral impacts by other vehicles etc.”
“it should be possible to delete this mass restriction so that vehicles such as large sedans, saloons, and some heavy sport utility vehicles can be properly type-approved as in the past”
The proposal asks for the deletion of the newly created mass restriction for M1 vehicles. It also recognises the specific conditions of heavy M1 vehicles with a high seating position.

The expert from Japan explained that the mass limit for passenger vehicles (M1 categories) was not justified. He also explained that it was inconsistent with the current definition of M1 vehicles, which currently has no mass limitation. The expert from EC agreed with the expert from Japan. He explained that it was not the original intention to impose this mass limit.

Q3Who is affected
Vehicle manufacturer
- For M1 vehicles over 3,500 kg maximum permissible mass, check the lowest seat's "R" point height from ground level.
- Check that height with the vehicle in the condition corresponding to the reference mass defined in paragraph 2.10.
- Where it is not more than 700 mm, treat that M1 vehicle as in the scope of this Regulation.
Component supplier
- No direct action for this role.
Technical service / Approval authority
- Be ready to test M1 vehicles over 3,500 kg maximum permissible mass that now come into the scope.
- For them, check that the lowest seat's "R" point is not more than 700 mm from ground level.
- Check this height in the condition corresponding to the reference mass defined in paragraph 2.10.
