Participants will determine if a suspect tire could have produced provided questioned imprints, then report results using the SWGTREAD 7-point scale of conclusions.

Sample Description: Physically printed images of a tire, known collected exemplars, and questioned imprints and a digitally downloadable supplemental file containing an additional set of known exemplars, intended to bolster participant confidence in their conclusions. The images are the same as those used in Test 5355, and reporting aspects are combined.

Samples ship in July.

This test is included on CTS' Scope of Accreditation to ISO/IEC 17043.
