UN R51 : Task Force Measurement Uncertainties (TF MU) guidelines to the objectives and rules of procedure

Document GRBP-71-05

17 January 2020

71st GRBP session (28-31 Jan 2020)

The text proposed by the Chairman of TFMU for the guidelines on the objectives and rules of procedure of the task force.

71st GRBP session (28-31 Jan 2020)

3. | UN Regulation No. 51 (Noise of M and N categories of vehicles)

9. The expert from OICA reported on the progress of the Task Force on Measurement Uncertainties (TF MU) (GRBP-71-04) and presented a strategy on how to handle measurement uncertainties in UN Regulations (GRBP-71-21). GRBP noted that the suggested approach could first apply to UN Regulations Nos. 51 and 117 and, at a later stage, to other UN Regulations as well.

10. Given the importance of this topic, GRBP decided to convert TF MU into an Informal Working Group on Measurement Uncertainties (IWG MU) and approved its Terms of Reference (GRBP-71-05, GRBP-71-31-Rev.1), as laid down in Annex IV. GRBP noted that IWG MU would be chaired by Norway, while OICA would act as secretary.

5. (d) | UN Regulation No. 117 (Tyre rolling resistance, rolling noise and wet grip)
