Annex 5 refers to M.R.1 for the description of the 3-D H machine

Annex 5 now says that the three-dimensional H-point machine is described in Addendum 6 of Mutual Resolution No. 1 (M.R.1). It names document ECE/TRANS/WP.29/1101/Amend.5. Before this supplement, Annex 5 described the back and seat pans and the body and leg elements of the machine, with Figures 5-1 and 5-2. This text and the two figures are deleted. A deleted footnote referred to SAE J826 (1995 version) for details of the construction of the machine. It said that the machine corresponds to the one in ISO Standard 6549: 1999.

The three-dimensional H-point machine is described in Addendum 6 of Mutual Resolution No. 1 (M.R.1) (document ECE/TRANS/WP.29/1101/Amend.5); see https://unece.org/transport/vehicle-regulations/wp29/resolutions

Figure reference in paragraphs 7.12.2. and 7.13.

Paragraphs 7.12.2. and 7.13. now refer to Figure A.2 of Addendum 6 of Mutual Resolution No. 1 (M.R.1). Before this supplement, they referred to Figure 5-2 of Annex 5. The other words of the two paragraphs do not change.

If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the 3-D H machine rearwards by applying a horizontal rearward load to the T‑bar until the seat pan contacts the seat back (see Figure 5-2 A.2 of Annex 5).Addendum 6 of Mutual Resolution No. 1 (M.R.1)).
Apply a 100 N ± 10 N load to the back and pan assembly of the 3‑D H machine at the intersection of the hip angle quadrant and the T‑bar housing. The direction of load application is maintained along a line passing by the above intersection to a point just above the thigh bar housing (see Figure 5-2 A.2 of Annex 5). Addendum 6 of Mutual Resolution No. 1 (M.R.1)). Then carefully return the back pan to the seat back. Care must be exercised throughout the remainder of the procedure to prevent the 3-D H machine from sliding forward.

“R-point” definition refers to M.R.1 (paragraph 2.18., footnote 3)

In item (b) of the “R-point” definition (paragraph 2.18.), a reference to Addendum 6 of M.R.1 replaces the reference to Annex 1 of R.E.3. Item (b) still applies “where relevant for the purpose of this Regulation”. Footnote 3 now names document ECE/TRANS/WP.29/1101/Amend.5 instead of document ECE/TRANS/WP.29/78/Rev.3, Annex 1.

Shall be established, where relevant for the purpose of this Regulation, in accordance with Annex Addendum 6 of Mutual Resolution No. 1 of the Consolidated Resolution on the Construction of Vehicles (R.E.3M.R.1).

R.E.3 references updated to Revision 7 (footnotes 2 and 4)

Footnote 2 to paragraph 1.1. now refers to document ECE/TRANS/WP.29/78/Rev.7 instead of Rev.6. Footnote 4 to paragraph 4.5.1. is about the distinguishing numbers of the Contracting Parties. It now refers to Rev. 7 instead of Rev. 3. Both footnotes now give the web address https://unece.org/transport/vehicle-regulations/wp29/resolutions.
