93. The expert from OICA presented GRVA-14-30, introducing GRVA-14-27 with amendments to UN Regulation No. 140 clarifying testing procedures for low gear steering. The expert from Canada noted the figures proposed for the steering robot mechanical power in the proposal and asked if OICA could share data supporting them. The expert from France expressed interest for the proposal, mentioned supporting material in ISO standards dealing with such testing conditions that could serve as a reference and required more time to study the proposal 93.
