This topic was raised by the Russian Federation during the September 2014 GRB session. Russia explained to the GRB that a new regulation on interior noise of vehicles would come into force from January 2015 within the Eurasian Customs Union (Russia, Belarus, Kazakhstan, Kyrgyzstan, and Tajikistan). Russia urged the GRB to revisit a previous recommendation to develop in coordination with ISO a uniform test method for measuring vehicle interior noise levels.
