UN R95 Supplement 7 (03 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 7 to the 03 series of amendments
Supplement 6 → 7
- What changed
- New paragraphs 2.36. to 2.39. define “Latched”, “Latch”, “Fully latched position” and “Secondary latched position”.
- New text in paragraph 5.3.1. gives two cases in which the requirement that no door opens during the test is deemed to be fulfilled.
- In case (b), the door does not open under a static tractive force of at least 400 N in the y-direction. The force is applied as the Figure shows, as close as possible to the window sill and to the door edge opposite the hinged side. The force is not applied to the door handle itself.
- Why
- Opinions differed between Technical Services about the definition of the word “open” in paragraph 5.3.1.
- The new definitions are taken from UN Regulation No. 135 Revision 1.
- The expert from OICA introduced a reduced applied force to the door, to improve the feasibility of the test.
Q1What changed9 changes
New definitions of “Latched”, “Latch”, “Fully latched position” and “Secondary latched position” (paras. 2.36. to 2.39.)
New paragraphs 2.36. to 2.39. define “Latched”, “Latch”, “Fully latched position” and “Secondary latched position”. “Latched” means any coupling condition of the door latch system, with the latch in a fully latched position, a secondary latched position, or between them. A “Latch” is a device that keeps the door closed relative to the vehicle body, with provisions for deliberate release (or operation). In the fully latched position, the latch retains the door in a completely closed position. In the secondary latched position, the latch retains the door in a partially closed position.
When the requirement that no door opens is deemed to be fulfilled (para. 5.3.1.)
Paragraph 5.3.1. requires that no door opens during the test. New text says that this requirement is deemed to be fulfilled in case (a) or in case (b). In case (a), it is clearly visible that the door lock is latched. In case (b), the door does not open under a static tractive force of at least 400 N in the y-direction. The force is applied as the Figure shows, as close as possible to the window sill and to the door edge opposite the hinged side. The force is not applied to the door handle itself.

Q3Who is affected
Vehicle manufacturer
- Check which conditions of your door latch system count as “Latched” under the new paragraph 2.36.
- Be ready for case (b): a static tractive force of at least 400 N in the y-direction on the door.
Component supplier
- No direct action for this role.
Technical service / Approval authority
- Assess the requirement that no door opens during the test by case (a) or case (b).
- In case (a), check if it is clearly visible that the door lock is latched.
- Case (b): check that the door does not open under at least 400 N static tractive force in the y-direction.
- Apply that force as the Figure shows, and not to the door handle itself.
- Apply that force as close as possible to the window sill and to the door edge opposite the hinged side.
