Unlock refers to transition of a doorlatch system into a state in which operation of the latch-release control is no longer inhibited, allowing the latch to disengage from the striker. Unlatching refers to transition into a state in which the latch and striker are no longer capable of withstanding separation forces, thereby allowing the door to move away from the vehicle body structure. Opening refers to the action by which a door is moved from its closed position to an open position through mechanical force or energizing an actuated device. Child Safety Lock System is a locking device which, when engaged, prevents operation of the interior door handle or other release device.

UN R155: Guidance for transformed vehicles
Reference Number: TFCS-37-05

Proposal to provide guidance on application of UN R155 to transformed vehicles. Transformations require new approval unless clear evidence shows original approval remains valid. Cyber-relevant modifications include addition of electrical/electronic systems, inappropriate interface connections, and wiring protection modifications. The approval authority determines whether transformation is cyber-relevant by assessing impact on original vehicle architecture, connection risks, cybersecurity management systems, and whether non-automotive equipment complies with relevant regulations. Manufacturers must provide documentary evidence including functional descriptions, connection details, software modifications, and compliance with original manufacturer instructions.

UN R155: Proposal for amendments from the workshop discussions
Reference Number: TFCS-37-04

Proposal to amend UN R155 by clarifying its scope to exclude certain equipment. The proposal amends paragraph 5.3.2. to require approval authorities to notify others of assessment methods and criteria. New paragraphs 8.2. and 8.3. establish that vehicle manufacturer installation of equipment with negligible intrinsic cyber security risk, or standard domestic, business or industrial equipment connected only for power, shall not require further assessment under paragraph 7, provided specified criteria are justified. Annex I is amended to include any equipment excluded from assessment pursuant to paragraphs 8.2. and 8.3.

UN R53: Presentation on transitional provisions
Reference Number: SLR-77-15

Based on SLR-76-03-Rev1 for R48 and tentatively applying WP.29/2024/76, IMMA presents transitional provisions for UN R53. The document outlines provisions applicable to all amendment series, including that Contracting Parties may grant type-approvals according to any preceding series and shall continue granting extensions of existing approvals. For the 05 series of amendments, specific dates establish when Contracting Parties shall accept or refuse type-approvals, with exceptions for equipment, parts, and unaffected vehicle systems.

Excerpts from session reports
GRE | Session 70 | 21-23 Oct 2013

21. The expert from Italy introduced ECE/TRANS/WP.29/GRE/2013/55 as amended by GRE-70-12 on the compliance obligation of lighting components with installation requirements. The proposal received some comments (GRE-70-21). GRE agreed to finalize this subject at its next session on the basis of a revised document, which the expert from Italy volunteered to prepare.

GRE | Session 71 | 31 Mar-3 Apr 2014

30. Based on an updated proposal tabled by the expert from Italy (ECE/TRANS/WP.29/GRE/2013/55/Rev.1), GRE resumed consideration of the insertion of compliance obligations with installation requirements, at the time of type approval of lighting components, according to the component UN Regulations. While several experts supported the proposal, some others were of the view that the underlying issue might go beyond the competence of GRE and that WP.29 should be asked for guidance. The Chair suggested clarifying and possibly rephrasing the wording “UN Regulations … and their series of amendments in force at the time of application for type approval”. GRE agreed to continue this discussion at the next session and decided that this proposal would become part of a horizontal document collecting common provisions of UN lighting and light-signalling Regulations (see agenda item 6 below).

GRE | Session 72 | 20-22 Oct 2014

21. GRE requested IWG SLR to consider GRE-71-23 and to consolidate into a horizontal document, harmonized definitions in lighting and light-signalling Regulations. For the same purpose, GRE referred to IWG SLR collective proposals, such as compliance obligations with installation requirements, definition of “type” with regard to the manufacturer and trade names/marks and provisions for the conformity of production, including those that had been referred back by WP.29 (ECE/TRANS/WP.29/GRE/2013/55/Rev.1, ECE/TRANS/WP.29/2013/68, ECE/TRANS/ WP.29/2013/69, ECE/TRANS/WP.29/2013/71, ECE/TRANS/WP.29/2013/72, ECE/ TRANS/WP.29/2013/76, ECE/TRANS/WP.29/2013/79, ECE/TRANS/WP.29/2013/83, ECE/TRANS/WP.29/2013/84, ECE/TRANS/WP.29/2013/85, ECE/TRANS/WP.29/ 2013/86, ECE/TRANS/WP.29/2013/87, ECE/TRANS/WP.29/2013/88, ECE/TRANS/ WP.29/2013/89, ECE/TRANS/WP.29/2013/94, ECE/TRANS/WP.29/GRE/2014/3).

GRE | Session 76 | 25-28 Oct 2016

10. GRE reviewed and unanimously adopted the pending amendment proposals so as to consolidate the existing Regulations before they are frozen and superseded by three new Regulations that are in drafting:

  • ECE/TRANS/WP.29/2013/68,
  • ECE/TRANS/WP.29/ 2013/69,
  • ECE/TRANS/WP.29/2013/71,
  • ECE/TRANS/WP.29/2013/72,
  • ECE/TRANS/ WP.29/2013/751,
  • ECE/TRANS/WP.29/2013/76,
  • ECE/TRANS/WP.29/2013/79,

  • ECE/TRANS/WP.29/2013/934,
  • ECE/TRANS/WP.29/2013/94,
  • ECE/TRANS/ WP.29/2014/31,
  • ECE/TRANS/WP.29/2014/32,

  • ECE/TRANS/WP.29/ GRE/2016/11,
  • ECE/TRANS/WP.29/GRE/2016/145
  • and Annex IV to ECE/TRANS/ WP.29/GRE/75.
The secretariat was requested to consolidate these proposals, according to the principle ‘one WP.29 document per Regulation’, and to submit them to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their March 2017 sessions. The experts from GTB, IEC and SAE volunteered to assist the secretariat by verifying the consolidated amendment proposals.

2Except for the part which was already adopted by WP.29 as ECE/TRANS/WP.29/2013/90/Rev.1 (note by the secretariat).
