GAR | GRB-66-21

12. The expert from China reported on noise problems and driving conditions in China in relation to the 03 series of amendments to Regulation No. 51 (GRB-66-21). In particular, he pointed out that further research would be needed to identify a relationship between the test cycles and noise problems as well as to develop a test method which would cover both the driving behaviours and noise issues. The Chair invited IWG ASEP to address these issues in cooperation with China.
