16、or building surface elements.The actualloading on building surfaces is quite complex,varying withwind direction,time,height above ground,building shape,terrain,surrounding structures,and other factors.These factorsare discussed in the literature in 2.2 and 2.3 and Footnotes 4and 5.NOTE1In applying the results of tests by this test method,it shouldbe borne in mind that the performance of a cladding system may be afunction of fabrication,installation,and adjustment,and that the specimenmay or may
