Unless

8、 otherwise specified, tests shall be conducted on production representative substrates by applying the tape per the following procedure: Clean test panels with a suitable solvent, such as a 50/50 mix of isopropyl alcohol and water, and allow to air dry. Peel the liner from the film in a smooth conti

9、nuous motion. Do not peel the film from the liner. Position the tape on the test substrate. For flat test panels, use the roller described in ASTM D 1000 (except roller rate: 50 mm/s) with no additional pressure, pass the roller over the full length of the tape once in each direction. For test parts

10、 with curved substrates, use a squeegee to apply the film. Test samples with applied tape shall be conditioned for 48 h at 23C and 50% relative humidity prior to environmental exposure. Tests shall be completed within 24 h after removal from the conditioning environment unless otherwise specified. 3
