UN R121: Proposal for Supplement 10 to the original series of amendments and Supplement 2 to the 01 series of amendments
Download in .pdf format Download in .docx format

Proposal pursuant to discussions on the application of footnote 18 under Table 1 concerning tell-tale symbols and the use of colours to convey different meanings. ISO standard 2575-2004, para. 5.1. allows for the use of different colours to convey a change in the operating condition. This proposal would remove the current footnote 18 text and application of the footnote to telltales 2, 9-12, and 19 pending a decision on the proposal to apply a revised footnote to the master lighting switch (tell-tale 1). Paragraph 5.4.1.1. of UN R121 references ISO 2575-2004 which was developed to simplify the application of UN R121 when colour changes are adopted in other UN Regulations; however, OICA submits that the footnote which references ISO 2575-2004 in relation to specific lighting devices or systems creates a degree of confusion. (If approved, this proposal would likely impact Supplement 3 to the 01 series rather than Supplement 2 given that WP.29 at its November 2017 session adopted the proposal to add a telltale and symbols for “Accident Emergency Call System (AECS)” and to align UN R121 with the 07 series of amendments to UN Regulation No. 16 as Supplement 2 to the 01 series.)

43. Recalling discussions at the previous GRSG session on the handling of colour changes of controls, tell-tales and indicators, the expert from OICA presented ECE/TRANS/WP.29/GRSG/2018/6 as a long-term solution. He explained that the proposal aimed to remove the references in Table 1 to footnote 18 and to only keep the reference to standard ISO 2575:2004. GRSG noted study reservations by the experts from France and the United Kingdom. GRSG agreed to resume consideration of this subject at its next session.

49. The expert from the Republic of Korea recalled the discussion on GRSG-115-14-Rev.1 at the previous session, to add into UN Regulation No. 121 a new symbol for “power on/power off” controls in vehicles equipped with an electric powertrain, such as electric vehicles. He thanked GRSG for the comments received, concluded that the current symbol in the UN Regulation was sufficient and that no further follow-up was necessary.

50. GRSG endorsed the request by OICA to defer discussion on ECE/TRANS/WP.29/GRSG/2018/6 to a further session.

51. GRSG agreed to resume consideration on this item at its next session in October 2019.

51. The expert from OICA recalled the discussion (ECE/TRANS/WP.29/GRSG/2018/6) at the previous GRSG session on the handling of colour changes of controls, tell-tales and indicators by deleting footnote 18 to table 1 and inserting only a reference to standard ISO 2575. Underlining the importance of colour for tell-tales, the expert from France preferred to keep footnote 18. The expert from OICA offered to review the proposal and to insert a new footnote for the tell-tales that impose colour. GRSG agreed to resume consideration of this subject at its next session on the basis of a revised document jointly prepared by the experts from France and OICA.
