Q1What changed7 changes
Ground clearance under item (b) (paras. 16.1. and 25.1.)
Paragraphs 16.1. and 25.1. apply to vehicles of the categories N2 with a maximum mass exceeding 8 t, N3, O3 and O4. Under item (b), the limit for vehicles other than those in item (a) is 500 mm, subject to the unchanged ‘in any case’ departure-angle rule. Under that rule, a departure angle up to 8° according to ISO 612:1978 with at most 550 mm ground clearance is deemed to comply. Before this supplement, item (b) said “500 mm or a departure angle according to ISO 612:1978 of 8°, whichever is less”.
Category G vehicles (para. 2.4. and the Annex 7 table)
Paragraph 2.4. now refers to the condition for the ground clearance “set out in this Regulation”, instead of “set out above”. In the first row of the Annex 7 table, “G” is deleted, and MG, N1G and “N2G with a MaxM* < 8 t” are added. The second row now also lists “N2G with a MaxM* > 8 t” and N3G. In the first row, three references “2.3./2.4./” now read “2.3./”. The second row now also refers to “2.4/”, next to “16.1. or 25.1.”.

Reasons

“The expert from Finland introduced ECE/TRANS/WP.29/GRSG/2019/14 proposing amendments to UN Regulation No. 58 to clarify the requirements on the installation on vehicles of rear underrun protection devices”
According to the proposer, a RUPD should be placed just behind the rear wheel and vertically near the ground level. For this reason, the deleted words are removed from paragraph 16.1.
Sources (2)
“A RUPD should be placed just behind the rear wheel and vertically near the ground level.”
“Thus the strikethrough text needs to be removed from paragraph 16.1.”
Paragraph 25.1. concerns the approval of the rear underrun protection of a vehicle. For this reason, the same change as in paragraph 16.1. is needed there.
Sources (2)
“Paragraph 25.1. concerns the approval of the rear under run protection of a vehicle.”
“Thus, the same change as in paragraph 16.1. is also needed in paragraph 25.1.”
In paragraph 2.4., the reference “set out above” is replaced with the more general reference “in this Regulation”.

“The reference "set out above" is replaced with more general reference "in this Regulation".”
