48. The expert from Germany introduced GRRF-83-05 looking for guidance on the possibility to develop snow tyre provisions for all tyres and vehicles categories as it was already existing for snow tyres of category C1, C2 and C3 for vehicles categories M and N by amending all relevant Regulations or by amending the scope of Regulation No. 117. The expert from Japan and the Russian Federation volunteered to contribute to the work item proposed by Germany. GRRF requested to add an agenda item dedicated to snow tyres on the agenda.
66. The secretariat reported that GRSP was using the abbreviation “VSF” as “Vehicle Seat Fixture” and proposed to stop using “VSF” as “vehicle stability function”. GRRF didn’t support this idea as “VSF” was not only used as an abbreviation but also VSF is part of an approval mark for certain vehicles type-approved according to Regulation No. 13.
51. The secretariat recalled the ongoing discussion on definitions, acronyms, abbreviations and symbols used in regulations. The secretariat announced that the relevant documents (based on GRRF-76-03 and GRRF-78-04) were added to the definitions page on the WP.29 website.
57. Following the suggestion of the WP.29, the secretariat introduced GRRF-78-04 containing a list of definitions in the Regulations under the responsibility of GRRF. The Chair of GRRF recalled GRRF‑76‑03 and noted that no follow-up action was defined. The secretariat announced that it was looking for a central and suitable location on the website to collect this useful information.
