7、humidity, and 16 h at -30 C. Samples shall be conditioned for 48 h at 23 +/- 2 C prior to exposure. Tests shall be completed within 1 h after removal from the conditioning environment. The cycle test samples shall be allowed to recover to 23 +/- 2 C prior to test. 3.3 FILM PROPERTIES 3.3.1 Appearanc

8、e The film and adhesive shall be transparent - clear or tinted. 3.3.2 Thickness (ASTM D 1000) Film 0.006 - 0.008 in (0.15 - 0.20 mm) Film and Adhesive 0.0075 - 0.010 in (0.19 - 0.25 mm) 3.4 RESISTANCE PROPERTIES 3.4.1 Sample Preparation Resistance properties test shall be conducted using 3 x 6 in (7

9、6 x 152 mm) sized steel and chrome plated steel panels. The test panels shall be solvent wiped with M-14J147 Petroleum Naphtha prior to applying the film per the following procedure: Peel off the backing paper from the film in a smooth, continuous motion. Do not pull the film from the paper. Liberal

10、ly apply a test solution of 5% sodium chloride to the panel surface. Apply some of the test solution to adhesive side of film. Position the film on the panel. Using a plastic squeegee, smooth out the film using firm overlapping strokes, working from the center of the panel. Carefully work out all ai

11、r bubbles. The film shall fully cover the face of the test panel. Test panels with applied film shall be conditioned for 48 h at 20 - 25 C and 50 +/- 5% relative humidity prior to starting the tests.
