57. The GRRF chair mentioned that document ECE/TRANS/WP29/2018/35 would still contain square brackets. WP.29 agreed to remove the square brackets and to agree on transitional provision dates (as reflected in para. 92).

4.7. | Consideration of draft amendments to existing UN Regulations submitted by GRRF

92. In ECE/TRANS/WP.29/2018/35, paragraphs 2.1.4., amend to read:

12.2.2.As from 1 September 2019, Contracting Parties applying this UN Regulation shall not be obliged to accept UN type approvals to the preceding series (02) of amendments, first issued after 1 September 2019.
12.2.3.Until 1 September 2021, Contracting Parties applying this UN Regulation shall continue to accept UN type approvals to the preceding series (02) of amendments to the UN Regulation, first issued before 1 September 2019.
12.2.4.As from 1 September 2021, Contracting Parties applying this UN Regulation shall not be obliged to accept type approval issued to the preceding series of amendments to this UN Regulation.

93. WP.29 noted the concern raised by the representative of OICA on the selection of an early date of application for the transitional provisions in paragraphs 12.2.3. and 12.2.4., which could create serious development difficulties, due to the introduction of new requirements compared to the very recently adopted 02 series of amendments, while vehicles are currently under development for the latter.

4.7.8. | Proposal for the 03 series of amendments to UN Regulation No. 79 (Steering equipment)
2. | Regulation No. 79

6. The expert from Germany presented (GRRF-85-06 and GRRF-85-07) the outcome of the IWG on the draft provisions applicable for ACSF of Category C (GRRF-85-02). He explained that the IWG resolved the remaining issue on the definition of the point at which, following the beginning of the Lane Change Procedure, the driver’s reaction should be understood. He added that, for this purpose, continuous lateral movement and lane centering provisions were added. He continued his presentation by reporting on the deliberation of the IWG on the definition of the target vehicle used for the sensor performance test proposed in Annex 8, para. 3.5.5. He added that the worst case scenario would be a sensor performance test with a motorcycle of category L3 target coming from the rear of the subject vehicle. He noted that no standard defining a test target L3 vehicle would exist to date and that therefore the IWG agreed on the compromise defined in Annex 8, para. 3.5.5.1. He noted that the definition of the target vehicle should be reviewed at a later stage as some experts had expressed their doubts that a L3 vehicle without fairing and windshield would indeed be the worst case scenario for this sensor performance test. He concluded his presentation with the description of the type approval tests requirements to be included in Annex 8. GRRF agreed that using a motorcycle without fairing and windshield would be appropriate until such times that a uniform target would be agreed.

7. GRRF reviewed in detail GRRF-85-02 and agreed on a number of amendments as reproduced in GRRF-85-02-Rev.1.

10. The expert from OICA presented (GRRF-85-08) a proposal for provisions applicable to ESF (GRRF-85-03).

11. GRRF reviewed the latter document in detail and agreed to insert the definition of ESF contained in GRRF-85-02.
