14、ards must include the decorative fabric facing on one of the 200 x 300 mm (8 x 12 in) faces. 4.4.1.2 Method: All fourteen (14) boards are subjected to the seven-step aging test shown in the table below. One board of each thickness 5 and 25 mm (0.2 and 1 in) is subjected to 180 peel tests per ASTM D9
15、03 after each step in the aging cycle, except as indicated below. Three peel test samples measuring 25 x 200 mm (1 x 8 in) are cut from each board for this testing. The peel test samples shall be cut immediately before the peel test and shall not be closer than 25 mm (1 in) to an edge or any other p
16、eel test sample. After cutting the peel test samples, the test chamber and all samples shall be returned to the conditions of the particular step before performing the peel test. 4.1.1.3 Required: There shall be no loss of adhesion between the fabric facing and the fiberglass core or delamination of
17、 the headliner during any steps of the aging cycle, or after the test is completed. All peel tests shall result in 100 percent destruction of the fiberglass surface, or must meet the minimum peel strength specified for the particular step of the aging test. The fiberglass board shall not lose shape
18、or integrity during any step of the aging test. Aging Cycle Minimum Peel Strength* N/m (lbf/in) Width 1. 24 hours at 38 C (l00 F.) and 100% RH 400 (2.3) 2. 24 hours at 82 C (180 F.) 400 (2.3) 3.
