<br />The daytime luminance for fluorescent orange, fluorescent yellow-green and
<br />fluorescent pink sheeting shall have a luminance factor of 25 minimum, 60 minimum and
<br />25 minimum respectively, in addition to ASTM 04956 Table 9.
<br />994-3.3.1 Accelerated Outdoor Test: The retroreflective and nonreflective
<br />materials shall meet the ASTM D4956 weathering requirements for performance.
<br />Retroreflective materials shall meet the minimum coefficient of retroreflection as listed in
<br />Table 11 in accordance with FM 5-571.
<br />994-3.4 Adhesive Backing:
<br />994-3.4.1 General: The adhesive backing of the retroreflective and
<br />nonreflective sheeting or film shall be either Class 1, Class 2 or Class 5 per ASTM 0956,
<br />Section 4.3. 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 04956, 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 />i 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 0882.
<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.
