25. The expert from the Russian Federation made a presentation (informal document GRSP-78-05) advocating for an increase in the mass of the mobile deformable barrier used in UN Regulation No. 95. He shared data showing how the mass of new vehicles is significantly larger than those being built at the time of the creation of the regulation, with even larger increases in the case of electric vehicles. The experts from the Republic of Korea, Germany and the Kingdom of the Netherlands agreed with the main premise of the Russian presentation but cautioned that other parameters in the design of the barrier may need to be updated, such as the stiffness. The expert from Spain asked if there were comparisons with the results from the tests carried out under multiple NCAP schemes, where a higher mass was already being used. The expert from Italy cautioned that even if newer cars were indeed heavier, the existing fleet in his country was significantly lighter than the typical new vehicles. GRSP agreed that this was an important issue that would require more work and decided to continue the discussion in the next session. Interested experts were encouraged to contact the expert from the Russian Federation.
