ASTM WK90698
Revision of F3611-22e1 Standard Specification for P225/60R16 97S Radial Low Tread Depth Standard Reference Test Tire
Rationale
1) Note 5 - update to SRTT sourcing: as originally announced during the October 2023 F09 meeting, the Ardmore site will be shut down no later than end of 2025. Production of the F3611 SRTT is being transferred to Poland. During the transition period, SRTT tires may originate from one or the other site. It is proposed to update F3611 with both sourcing, including:
a. an up to date company name for the Ardmore site.
b. the address already used for the C3 SRTTs (also supplied out of Europe) as balloted and approved last year.
2) 9.5.2 & 9.5.5: Linked to the sourcing change, Michelin Europe is not using the same type of durometer as used in the US. It is proposed to align the test method description for tire tread hardness with what has been historically used for the C3 SRTTs. This proposed description encompasses different durometer models (including digital in addition to the historical analog devices).
3) 2. & 3.1.5: updated references to SRTTs recently created and approved.
