UN R49 | 05 series of amendments
(2008)
|
GRPE-82-24: 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.

Discussion from 82nd GRPE session (12-15
Jan 2021)
|
|
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.

4. Regarding the proposal to remove from global technical regulation (gtr) No. 4 on the Worldwide harmonized Heavy Duty Certification procedure (WHDC) the remaining options on hot soak period and cold start weighting factors, GRPE noted that the proposal ECE/TRANS/WP.29/2010/48 had been submitted to WP.29 and AC.3, for consideration at their June 2010 sessions and establishing into the Global Registry as Amendment 2 to the gtr. With regard to the corresponding alignment of Regulation No. 49, GRPE welcomed the anticipated adoption by WP.29 at its March 2010 session of ECE/TRANS/WP.29/2010/51.

- the constants used for CVS verification,
- the formula for regression analysis according to Annex 4, Appendix 3, and
