Tape Subgroup

Guideline for Forensic Examination of Pressure Sensitive Tapes:

-Descriptions of various tapes, manufacturing similarities and differences and the steps in a forensic analysis.

Process to Create:

-To provide a standardized approach to an analysis generally conducted randomly and infrequently in forensic laboratories.

-Drafts offered to community for comment

-Comments reviewed by the tape subgroup and incorporated or denied. All changes presented to the full SWG for their review.

-Final draft voted on by full SWG - If approved, submitted to ASTM for incorporation

-Enforcement - Voluntary
