The retroreflective and nonreflective sheeting or film, after application, shall <br />tightly adhere to the application surface and show no discoloration, cracking, crazing, <br />blistering or dimensional change. <br />994 -3.4.2 Protective Liner: The protective liner over the adhesive backing <br />shall be removable from the adhesive backing by peeling without soaking in water or other <br />solvents and without breaking, tearing or removing any adhesive from the adhesive <br />backing in accordance with ASTM D4956, Section 7.10. <br />994 -3.5 Film: The exterior film of the sheeting shall be a flexible, smooth - surfaced, <br />moisture resisting material and shall have sufficient strength and flexibility to be easily <br />handled, cut to shape, processed and applied without stretching, tearing, or other damage. <br />In addition, retroreflective sheeting shall have a transparent exterior film. <br />994 -3.6 Tensile Strength: The retroreflective and nonreflective sheeting or film shall <br />have a minimum tensile strength of five pounds -force so that the sheeting can be handled, <br />processed and applied without damage to sheeting. The tensile strength shall be tested in <br />accordance with ASTM D882. <br />994 -3.7 Physical Properties: The retroreflective and nonreflective sheeting or film <br />material shall meet the ASTM D956 minimum requirements for specular gloss, shrinkage <br />and flexibility. <br />994 -3.8 Workability: The retroreflective and nonreflective sheeting or film shall <br />permit preapplication handling, positioning, cutting by hand or die machine and oven <br />drying. In addition, retroreflective sheeting shall permit color processing. <br />994 -3.9 Chemical Resistance: The retroreflective and nonreflective sheeting or film <br />shall be chemically resistant so as to permit cleaning with naphtha and mineral spirits, <br />turpentine, mild soaps, detergents and alcohol. <br />994 -3.10 Color Processibility: The retroreflective sheeting shall permit color <br />processing with compatible transparent and opaque process inks as approved by the <br />sheeting manufacturer and listed on the QPL. <br />Table 13 <br />Type VII Sheeting <br />Minimum Coefficient of Retroreflection <br />(cd /(Foot - candle ft2)) [(cd /((1x m2))] <br />Observation /Entrance <br />Angle (degree) <br />White <br />Yellow <br />Red <br />Orange <br />Blue <br />Green <br />Brown <br />Fluorescent <br />Orange <br />Fluorescer <br />Yellow <br />0.2/4 <br />380 <br />304 <br />95 <br />250 <br />19 <br />38 <br />19 <br />180 <br />220 <br />0.5/ -4 <br />250 <br />195 <br />55 <br />100 <br />12 <br />25 <br />8 <br />60 <br />145 <br />0.2/30 <br />220 <br />176 <br />48 <br />1.10 <br />11 <br />22 <br />9 <br />85 <br />125 <br />0.5/30 <br />135 <br />1.05 <br />30 <br />1 50 <br />7 <br />14 <br />3 <br />33 <br />75 <br />aMarch 2007 01000 -217 03- 4122.D <br />
