UN R16 Supplement 1 (10 series) · UNECE Regulation No. 16 (ECE R16) — Uniform Provisions Concerning the Approval of: Safety-Belts and Restraint Systems, for Occupants of Power-Driven Vehicles.
UN R16 — Supplement 1 to the 10 series of amendments
Base text → Supplement 1
- What changed
- The buckle-opening test load in paragraph 7.8.2. is now 30 daN on each of the two straps of a two-point lap belt. For a three-point belt, it is 30 daN on the two clamped straps of the diagonal belt part together.
- These loads replace the force of 60n daN on all the straps. For S-type belts, the manufacturer and the technical service agree on forces that simulate a similar load on the buckle.
- Annex 15, footnote 1 now refers to Addendum 6 of Mutual Resolution No. 1 (M.R.1) for the procedure, instead of the Consolidated Resolution (R.E.3.).
- Why
- The expert from Germany proposed the change to clarify how to perform the buckle-opening test, which simulates the load caused by a 60 kg body.
- The specifications of the 3-D "H"-point machine had been updated and transferred from R.E.3 to M.R.1.
Q1What changed6 changes
Load for the buckle-opening test by belt type (para. 7.8.2.)
For a two-point lap belt, the load goes on each side of the buckle, with 30 daN on each of the two straps. For a three-point belt, the upper and lower straps of the diagonal belt part are clamped together and take 30 daN together. S-type belts are tested in a similar way, depending on their geometry. The forces for them are agreed between the manufacturer and the technical service and simulate a similar load on the buckle. An additional crotch strap is not taken into account for this test. Before, all the straps were subjected to the force of 60n daN, where n is the number of straps linked to the locked buckle.
New reference for the procedure (Annex 15, footnote 1)
Annex 15, footnote 1 now says that the procedure is described in Addendum 6 of Mutual Resolution No. 1 (M.R.1) (document ECE/TRANS/WP.29/1101/Amend.5). Before, it referred to Annex 1 and its Appendices 1, 2 and 3 to the Consolidated Resolution on the Construction of Vehicles (R.E.3.).
Q2Why it changed
- Proposed by
- Expert from Germany (for the Annex 15 footnote, the expert from the Netherlands)
- Working party
- GRSP, 76th session (December 2024)
Reasons
The expert from Germany proposed the change to clarify how to perform the buckle-opening test described in paragraph 7.8. This test simulates the load caused by a 60 kg body.

“This proposal aims to clarify, how to perform the buckle-opening test, simulating the load caused by 60 kg body, described under paragraph 7.8. of the UN Regulation”
“The expert from Germany re-introduced ECE/TRANS/WP.29/GRSP/2024/6 to clarify how to perform the buckle-opening test, simulating the load caused by a 60 kg body, described in paragraph 7.8. of the UN Regulation.”
The expert from the Kingdom of the Netherlands updated the proposal with the specifications of the 3-D "H"-point machine. These specifications had been updated and transferred from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1).

Q3Who is affected
Vehicle manufacturer
- Update your references for the Annex 15 procedure from R.E.3. to Addendum 6 of Mutual Resolution No. 1 (M.R.1).
Component supplier
- For a two-point lap belt, load each side of the buckle, with 30 daN on each strap.
- For a three-point belt, clamp the upper and lower diagonal straps together and apply 30 daN to them together.
- For an S-type belt, agree with the technical service on forces that simulate a similar load on the buckle.
- Do not take an additional crotch strap into account in the buckle-opening test.
Technical service / Approval authority
- Check that buckle-opening tests use the loads by belt type in paragraph 7.8.2., not the former force of 60n daN.
