26. The representative from EC introduced ECE/TRANS/WP.29/GRPE/2021/6 as amended by GRPE-82-22 proposing a new 07 series of amendments to UN Regulation No. 49. The representative from FSD requested clarifications on the proposal to remove provisions related to On-Board Diagnosis (OBD) from the text. The representative from EC said that there have been considerations to remove OBD provisions from UN Regulation No. 49 to align with existing legislation in the EU, but that they were finally kept in. He suggested to look at the opportunity to include such provisions for the whole vehicle, not only for emission related purposes, possibly in UN Regulation No. 0.
27. The Chair asked whether this topic was being discussed at the IWG on International Whole Vehicle Type Approval (IWVTA). The representative from EC stated that this issue had now been identified and needed to be considered by the IWG on IWVTA. The GRPE Ambassador to the IWG on IWVTA agreed to initiate a discussion on the potential to include OBD and Repair and Maintenance Information (RMI) into UN Regulation No. 0.
28. GRPE endorsed the proposals for a new 07 series of amendments to UN Regulation No. 49 and requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2021/6 and GRPE-82-22, as amended by Addendum 1 to WP.29 and AC.1 for consideration and vote at their June 2021 sessions as draft 07 series of amendments to UN Regulation No. 49.

29. The representative from OICA introduced GRPE-82-23 and GRPE-82-24 proposing some corrections to the 06 and 05 series of amendments to UN Regulation No. 49 respectively. The representative from the EC required further clarifications on the proposal to amend Table 7 that would imply a misalignment with other existing national legislations. GRPE agreed to consider those proposals after further justifications are elaborated by interested stakeholders.

Proposal makes changes to take into consideration the availability of gases for flame ionization detectors and the linearization of the gas analyzer.
UN R49 defines no linearity requirements for humidity sensors. As the humidity content of the intake air is an essential measure for the calculation of the specific exhaust emission, it is important to add requirement for humidity sensor (Reference: ISO 16183 the accuracy of the absolute humidity shall be +- 5%).
The reasoning for the other amendments to Table 7 is the following.
As the gas divider is a necessary tool to verify the linearization of the gas analyzer it is mandatory that the deviation of the gas divider is lower than that of the instrument under test. In combination with a calibration gas which has an accuracy of 1 % and a gas divider, which has an accuracy of 1 % it is only possible to reach a guaranteed analyzer accuracy of 2 %.
Annex 4B – Amendments to paragraph 9.3.3.1
In the automotive industry Helium is used as so fuel gas for flame ionization detectors (FID) to measure Hydrocarbon emissions. In the FID fuel gas Helium is mixed with Hydrogen in a ratio of 40 % H2 and 60 % He. The annual fluctuations of the helium global market lead to an insufficient supply with FID fuel gas, like happened lately during summer 2018. In order to prevent the industry from the fluctuations of the global helium market, the US legislation reacted already in 2014 and allowed the usage of Nitrogen as batch gas for the FID fuel gas.
