Harmonized International Standard Call Letters PSTC 107 Date of Issuance 10/00 Revised 10/03 Revised 05/07 Shear Adhesion of Pressure Sensitive Tape 1. SCOPE 1.1 These procedures help determine the ability of a pressure sensitive tape to remain adhered under a constant load applied parallel to the surface of the tape and substrate. Shear adhesion (shear resistance) is the ability of a tape to resist static forces applied in the same plane as the backing. 1.1.1 Procedure A measures the shear adhesion when applied to a vertical standard steel panel. 1.1.2 Procedure B measures the shear adhesion when applied to a vertical panel covered with NIST (National Institute of Standards and Technology, USA) SRM 1810A standard fiberboard. 1.1.3 Procedure C measures the shear adhesion when applied to vertical panel covered with a fiberboard agreed upon by the buyer and seller. 1.1.4 Procedure D measures the shear adhesion of reinforced filament tape when applied to a horizontal standard steel panel. 1.1.5 Procedure E measures the shear adhesion of a filament-reinforced tape when applied to a horizontal panel covered with NIST SRM 1810A standard fiberboard. 1.1.6 Procedure F measures shear adhesion of a filament-reinforced tape when applied to a horizontal panel covered with a fiberboard agreed upon by the buyer and seller. 1.1.7 Procedure G is the same as Test Method A except the test is conducted at an elevated temperature and a 10-minute dwell time. 1.2 These procedures
