This test involves the analysis and comparison of adhesive tape evidence. Participants receive three pairs of pressure sensitive tape samples, each containing one known sample and one questioned sample. Using chemical analysis and physical examinations (including optional physical end matching), participants determine within each pair if the questioned item could have originated from the known item.

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

Samples ship in May.
