33. The expert from the Republic of Korea presented GRSG-117-32 to clarify the provisions on tests of CMS when installed on a vehicle. The expert from Germany clarified that UN Regulation No. 46 would already cover the test of installed systems on vehicles and therefore he would not see the need for additional test provisions. The Chair invited the experts to check if UN Regulation No.46 would need to be amended and invited Korea to come up with a related proposal at the next GRSG session, if necessary.
