13、01 (painted panels only) 3.9 PREPARATION OF TEST PANELS FOR RESISTANCE PROPERTIES The film shall be tested on actual plastic or paint panel substrates (refer to para. 3.7.1 approved substrates), by applying the film per the following procedure. Cut film samples 75 x 100 mm. Clean test panels with a
14、50/50 solution of distilled water and isopropyl alcohol. Peel off the backing liner from the film in a smooth continuous motion. Do not pull the film from the liner. Position the film on the test panel. Using a plastic squeegee, smooth out the film using firm overlapping strokes, working from the ce
15、nter of the panel. Carefully work out all air bubbles. Test panels with applied film shall be conditioned for 48 h at 23 +/- 2 C and 50 +/- 5% relative humidity prior to exposure. Tests shall be completed within 4 h after removal from the conditioning environment, unless otherwise noted. 3.10 RESIST
16、ANCE PROPERTIES After each of the following exposures, the film must not show evidence of edge curling, delamination, moderate yellowing, loss of adhesion or any other effect which would detract from its proper function or appearance. Note: If the substrate material delaminates, shrinks or deforms u
17、nder the following conditions, it is not a cause for rejection providing the film does not delaminate. 3.10.1 Humidity Resistance Test Method: Condition the test panel in a humidity cabinet for 7 days at 38 +/- 2 C and 95 - 100% relative humidity. 3.10.2 Heat and Cold Resistance Test Method: Conditi
