Specification Requirements4.1 The properties of woven awning and canopy fabricsshall conform to the specification requirements listed in Table1.5. Significance and
10、Use5.1 Fabrics intended for this end-use should meet all of therequirements listed in Table 1.5.2 It should be recognized that fabrics can be producedwith an almost infinite number of combinations of constructionvariables (for example, type of fibers, percentage of fibers, yarntwist, yarn number, wa
11、rp and pick count, chemical andmechanical finished.) Additionally, fashion or aesthetics dictatethat the ultimate consumer may find acceptable articles madefrom fabrics that do not conform to all of the requirements inTable 1.5.2.1 Hence, no single performance specification can possi-bly apply to al
12、l the various fabrics that could be utilized for thisend-use.5.3 The uses and significance of particular properties andtest methods are discussed in the appropriate sections of thespecified test methods.5.4 The significance and use of particular properties and testmethods are discussed in the approp
