Dry the scrib
16、ed area with a paper towel, cloth or air pressure and immediately apply, with firm thumb pressure, a min of 13 cm of ESF-M3G48 tape. Remove the tape by pulling one end at a 90 angle at a moderate speed. The following conditions shall be basis for rejection: . Removal of paint beyond 1.6 mm from any
17、scribe line. . Any evidence of blistering or dulling of the paint at either the scribe or any other area of the panel. 3.6.2 Weathering Resistance Panels prepared in accordance with paragraph 3.3 shall show a min degree of fading, chalking, or dulling. No cracking when bent over a 51 mm mandrel on 6
18、.4 mm thick elastomeric substrate. No increase of brittleness or loss of adhesion is permitted and panels shall be completely free from evidence of cracking, checking, blistering, or peeling when exposed as follows: . Florida Exposure (Miami area) 12 months at 5 facing south . Accelerated Weathering
