Ultraviolet Resistance of Extemnal Coatings. Procctive coatings rquirvd to mcc soction 18.4 (Environmcntal Tcst) shall be cvalualcd for resistance to ulraviolat ellxcts using a minimum 1000 hours cxposurc in acordance with ASTM G53, Standard Practice for Operating LighI- (ud Wuler-Exposure Apparalus (Fluorescent UV-Condensation Type) for Exposure 0[ Nonmetallic Muterials. There shall bec n0) cvidencc of blistering, CTacking, dhalking or soltcning. Fibers. Stuructural rcinfiorcing filanent matcrial typcs shall be glass fiber, aramid fber or carbon fiber. If carbon fibcr rinforcmcnt is uscd, uhe dcsign shall incorporalc mcans to prevcnt galvanic corrosion of mcallic componcnts of thc fucl containct. Resins. Thc malcrial for imprcgnation may be thcrmoscting or thermoplastic resin. Examples of suitablc matrix matcrials are cpoxy, mdificd cpoxy, polycsta and vinylcstcr thcrmoscting plastics, and polyethylenc and polyamide thcrmoplastic matcrial.
