Any evidence of blistering after tape removal. 3.5.2 Weathering Resistance 3.5.2.1 Accelerated Weathering The enamel shall exhibit no checking and no more dulling
14、 or color change than the approved master sample on file in the Body Materials Section. The enamel shall not blister nor show any loss of adhesion when subjected to the following test: . FLTM BO 101-01 400 h . 24 h water immersion. Check adhesion per paragraph 3.5.1. 3.5.2.2 Florida Exposure (Miami
15、Area) The enamel shall exhibit no checking and no more dulling or color change than the approved master sample on file in the Body Materials Section. The enamel shall not blister nor show loss of adhesion when subjected to 1 cycle of the following test: . 160,000 langleys (approximately 1 year) min
16、exposure at 45 facing south in the Miami, Florida area. . 24 h water immersion. Check adhesion per paragraph 3.5.1. Note: In the event of differences in the test results of accelerated weathering (3.5.2.1) and Florida exposure (3.5.2.2), the results of the Florida exposure (3.5.2.2) shall govern. EN
