| GRBP | Session 79 | 6-9 Feb 2024 |
9. The expert from OICA presented an interim report on the ongoing ASEP/ RD-ASEP study (GRBP-79-45) which included a first set of data on RD-ASEP monitoring according to the 03 series of amendments to UN Regulation No. 51. GRBP noted the low response rate and encouraged all type approval authorities and technical services of contracting parties applying UN Regulation No. 51 to transmit the relevant data, as a sufficient number of datasets are needed to conduct a good study. In reply to a question from the expert of EC, the expert of OICA indicated that they would need around 1,000 data sets to conduct a good study on RD-ASEP. The expert from OICA also clarified that only an excel data sheet should be transmitted, without a pdf report. |
