44. The expert from France presented an evolution study of UN Regulation No. 73 on lateral protection devices and proposed to review the test requirements with respect to the geometric and loading/displacement criteria (GRSG-113-11-Rev.1). Thus, he introduced GRSG-113-12 amending the geometric criteria and GRSG-113-13 amending the static force. GRSG welcomed the research study and the proposed amendments. GRSG noted general support and agreed to resume consideration of this subject at its next session in April 2018. The secretariat was requested to circulate GRSG-113-12 and GRSG-113-13 with official symbols and to keep GRSG-113-11-Rev.1 as a reference document.

Reference Number: GRSG-113-11/Rev.1

Discussion of the evolution of UN R73 with a proposal to update load requirements for lateral protection devices: - Application of a force of 3kN perpendicular to the device (as currently defined)
- Max. strain under loading at 90mm over the 250mm most rearwards part
- Max. strain under loading at 450mm on the other parts.

Proposal for the 02 series of amendments to UN Regulation No. 73
|
|
Reference Number: GRSG-113-13
|
|
Proposal to update the horizontal static force requirement for lateral protection devices to 3 kN and the deflection under load criteria to 90 mm over the rearmost 250 mm of the device and 450 mm over the remainder of the device. The purpose is to reduce the risk of running over a person (e.g., a motorcycle rider) during a lateral collision.
