Proposal to ensure the continuity of the American Society for Testing and Materials (ASTM) Method E1337 for the measurement of the Peak Braking Coefficient (PBC) in UN Regulation No. 140, by introducing a reference to the new ASTM Standard Reference Test Tyre F2493.
18. The expert from ETRTO reported that, in 2020-2021, the American Society for Testing and Materials (ASTM) would be phasing out the Standard Reference Test Tyre SRTT14 (ASTM E1136) which was referenced in UN Regulations Nos. 108 and 117 (GRBP-71-06). Therefore, these references would need to be replaced by SRTT16 (ASTM F2493) tyre, and the test procedure should be amended accordingly. The Chair invited ETRTO to submit an official document with draft amendments to UN Regulation No. 117 for consideration at the next session. The expert from BIPAVER volunteered to cooperate with ETRTO with the aim to prepare similar amendments to UN Regulation No. 108.
90. The expert from OICA introduced GRVA-13-24 proposing an update for the measurement of the Peak Braking Coefficient (PBC) in UN Regulation No. 140, by introducing a reference to the new American Society for Testing and Materials (ASTM) Standard Reference Test Tyre F2493. The expert from Canada mentioned that the proposal was consistent with similar work done in other jurisdictions and supported it.

99. The expert from Canada noted that a similar amendment had been introduced in the 01 series of amendments to UN Regulation No. 13-H. He inquired whether it would be needed for the original series too. The expert from OICA answered that it would make sense. The secretariat prepared the corresponding document, GRVA-14-55.
