Additional materials covering task force topics and possible time frame for EC proposal on Euro 5 sound limits.
21. The experts from EC informed GRB about an ongoing study on Euro 5 sound level limits of L-category vehicles (GRB-65-16 and Add.1), with the aim to investigate the potential for lower limits and to prepare justified proposals for amendments to EU Regulation No. 168/2013 and, at a later stage, to UN Regulations Nos. 9, 41 and 63. According to the experts, the study had been launched in response to frequent complaints from citizens over the excessive levels of sound emissions from L-category vehicles, which were often perceived as disturbing and harmful noise for the public health.
22. The experts of Germany, Netherlands, IMMA and OICA pointed out that the underlying problems were not because of the prescribed limits for new vehicles, but due to retrofitting and tampering with silencers of the vehicles in use. Thus, these experts were of the view that only reducing the sound level limits in the above Regulations would not improve the situation, unless accompanied by efficient enforcement measures and market surveillance. GRB agreed to study the relevant documents and to monitor the developments at the EU level.
