Latest Changes to WP.29 Regulations
The following table provides a listing of regulatory texts published during the past six months. These texts are the consolidated versions of the changes published by the United Nations based upon the proposals formally adopted by WP.29. Because the original adopted proposals often include last-minute amendments or corrections, the UN prepares these consolidated versions of the final approved texts as a convenience. The original documents as considered during the adoption votes in WP.29 legally remain the official texts.

Proposal to insert a minimum luminance gradient as an alternative criteria. The current text requires a certain “asymmetry” of the Light Emitting Area (LEA) in order to ensure a “minimum worst-case gradient”; however, this requirement has been deemed too design-restrictive.

3 Nov 2020 2021-01-04 08:53:17 UTC 2 01 series of amendments Based upon the adopted proposal: WP.29/2020/29

Proposal to:

  1. clarify that the application of an AECD approval to other vehicle categories than M1 and N1 is not mandatory,
  2. align the power supply requirement of Part III, para. 34.1 with the corresponding requirement in Part II, para. 25.1.
  3. clarify with regard to para. 34.1 that if the vehicle is equipped with both
    • -a “back-power supply” as listed in para. 35.10.1 and
    • -a “Power supply other than back-up power supply mentioned in paragraph 35.10.1” as listed in para. 35.10.2
    both should be tested according to Annex 9. The “Power supply other than back-up power supply mentioned in paragraph 35.10.1” should indeed only be tested if it is the only power supply for the AECS.
  4. include two-year transitional provisions
  5. remove the exclusion of M1 and N1 not equipped with a side airbag and to specify that the AECS shall be able to output the navigation solution in an NMEA-0183 protocol format (RMC, GGA, VTG, GSA and GSV message), among other clarifications.

UN R144 | Amendment 1 (2020)
3 Nov 2020 2021-01-04 08:52:02 UTC 1 00 series of amendments | Supplement 1 Based upon the adopted proposal: WP.29/2020/24

Proposal to correct erroneous references (to annexes in the regulation as well as to UN R94 and R95) in the text and to correct an inconsistency in the text (paragraph 26.7.2. refers to situations where the AECS is not equipped with a back-up power supply; however, the subparagraph 26.7.2.3. refers to an AECS with a back-up power supply).

UN R62 | Amendment 4 (2020)

    • sampling rate of at least 100 Hz for dynamic testing,
    • specification of filters and cut-off frequency for determination of lateral acceleration,
    • option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

UN R90 | Revision 3 | Amendment 6 (2020)
2 Nov 2020 2021-01-04 07:35:50 UTC 3 6 02 series of amendments | Supplement 6 Based upon the adopted proposal: WP.29/2020/8

Proposal to introduce a generic drawing to improve interpretation of the regulation, especially with regard to contactable parts (sphere protocol). The proposal clarifies which requirements apply to which part of the windscreen wiper and thus clarifies whether parts may be “exempted”.

Proposal to update UN R0 in line with the restructuring of the UN lighting regulations, to introduce use of the UN on-line system for sharing information on acceptance of type approvals, and to amend the annex concerning “Specifications of the IWVTA DoC”, including replacing a reference to the type approval number with the VIN.

01 series of amendments | Supplement 1 Based upon the adopted proposal: WP.29/2019/75

Proposal from the IWVTA informal group concerning the acceptance of Limited IWVTA approvals.

UN R0 | Revision 1 (2020)
30 Sep 2020 2020-10-05 14:46:33 UTC 1 01 series of amendments Based upon the adopted proposal: WP.29/2018/82

Proposal to update the list of UN Regulations subject to UN R0 (Annex 4), including addition of UN R14 (safety belt anchorages) and UN R34 (rear impact and fire risk).

UN R129 | Revision 4 (2020)
24 Sep 2020 2020-10-05 14:58:55 UTC 4 02 series of amendments | Supplement 3 Based upon the adopted proposal: WP.29/2018/42

Proposal to specify the proper use and behavior of an adult safety-belt used to install a non-integral Enhanced CRS during dynamic tests. These instructions are present in UN R44, but not in UN R129. Therefore, this proposal would align the two regulations. The proposal also clarifies that the opening force applied to the ISOFIX attachments of a complete seat or of a seat component under the test protocol is 50 ± 1 N.

03 series of amendments Based upon the adopted proposal: WP.29/2018/45

Proposal to introduce provisions for the approval of universal belted and specific-to-vehicle belted child restraint systems. The proposal also introduces provisions for lower tether straps. This proposal represents the culmination of the “Phase 3” amendments prepared by the CRS informal group. This amendment concludes the three-phased program to develop a new UN Regulation for CRS to supersede UN R44.

UN R120 | Revision 2 (2020)
23 Sep 2020 2020-10-05 15:07:37 UTC 2 02 series of amendments Based upon the adopted proposal: WP.29/2018/52

Proposal to align UN R120 with the proposed 05 series of amendments to UN R96.

UN R14 | Revision 6 (2020)
27 Jul 2020 2020-08-04 14:50:59 UTC 6 07 series of amendments | Supplement 4 Based upon the adopted proposals: WP.29/2012/42

Text adopted by the Working Party on Passive Safety (GRSP) at its fiftieth session to align UN Regulation No. 14 with the provisions of draft Regulation on Child Restraint Systems (CRS).

WP.29/2012/97

Text adopted by the Working Party on Passive Safety (GRSP) to update provisions of UN Regulation No. 14 in order to delete erroneous cross-references in text, making reference only the “adjusting system” which is defined in section 2 of the Regulation.

07 series of amendments | Supplement 5 Based upon the adopted proposal: WP.29/2013/103

Proposal as approved by the GRSP to introduce exemptions for vehicles not intended for transporting children during normal use.

07 series of amendments | Supplement 6 07 series of amendments | Supplement 7 Based upon the adopted proposal: WP.29/2016/35

Proposal to introduce: (i) a definition of flexible shoulder adjustment device for height, (ii) provisions for its testing and (iii) to define its strict field of installation for vehicle categories M2 and M3.

08 series of amendments Based upon the adopted proposal: WP.29/2017/128

Proposal to transfer all ISOFIX requirements from UN R14 into a new UN Regulation. Within the context of the international whole vehicle type approval program, the removal of these CRS anchorage provisions would align UN R14 with its Australian Design Rule counterpart and enable Australia to apply the revised UN R14 narrowed down to adult seat-belt anchorages only.

07 series of amendments | Supplement 8 Based upon the adopted proposal: WP.29/2017/58

Proposal to align UN R14 with recent changes to UN R16 on occupant restraint systems. Two “Booster Seat” fixtures (ISO/B2 and ISO/B3) were added to UN R16 to coincide with the implementation of Phase 2 of UN R129 (enhanced child restraint systems). These fixtures were developed within ISO/TC 22/SC 36/WG 2 (Child Restraint Systems) and follow the principle already established in Regulations 16 and 129 to ensure child restraint to car compatibility. An additional “Reduced-Size Rearward Facing toddler CRS” fixture (ISO/R2x) was added to facilitate compatibility in small cars/seating positions. The ISO/B2 booster seat fixture was added in the i-Size concept. Lateral facing fixtures (ISO/L1 and ISO/L2) have been upgraded.

07 series of amendments | Supplement 6 | Corrigendum 1 Based upon the adopted proposal: WP.29/2019/56

Proposal to update a reference regarding ISOFIX exemptions permitted under paragraph 5.3.8.8. (related to vehicles with one seat position per row). The reference should read 5.3.8.8. and 5.3.8.9.

Earlier texts may be available through the UN Official Document System.
