High Intensity Prismatic Reflective Sheeting for road sign

High Intensity Prismatic reflective sheeting for road sign

RT-4940 reflective vinyl for warning road sign which is a non-metalized microprismatic lens retroreflective sheeting designed for production of reflective signs and traffic control signs that are exposed vertically in service.  When applied to properly prepared sign substrates,Acrylic prismatic reflective sheet provides long-term reflectivity and durability. reflective sheet for warning road signs which is available in the following colors: White,green,yellow,red,blue,F-yellow,orange etc

1.Super High reflectivity
2.Premium quality microprismatic retroreflective performance
3.Field proven durability on safety devices worldwide

4.Uniform daytime and night-time visual appearance

5.Reflective vinyl for warning road sign

Photometries
Daytime Color (X,Y)
The chromaticity coordinates and total luminance factor of the retroreflective sheeting conform to Table A Daytime Color Specifications Limit (see Note 1).

Color Test – Ordinary Colored Sheeting Conformance to standard chromaticity (x, y) and luminance factor (Y %) requirements shall be determined by instrumental method in accordance with ASTM E 1164 on sheeting applied to smooth aluminum test panels.
The values shall be determined on a spectrophotometer.

Computations shall be done for CIE Illuminant D65 and the 2° standard observer (see Note 2)

Coefficients of Retroreflection (RA)
The values in Table B and C are minimum coefficients of retroreflection expressed in candelas per lux per squaremeter (cd/lux/m2).

Coefficients of Retro reflection (Required by North American Market)
Conformance to coefficient of retro reflection requirements shall be determined by instrumental method in accordance with ASTM E-810 “Test Method for Coefficient of Retroreflection of Retroreflective Sheeting” and per E-810 the values of 0° and 90° rotation are averaged to determine the RA in Table B

Coefficients of Retro reflection (Required by European Market)
Measured in accordance with the procedure specified in CIE 54.2, using CIE standard illuminant A, the minimum initial coefficient of retroreflection RA (cd/lux/m2) of retroreflective material, shall meet or exceed the values in Table C.

The coefficient of retroreflection (RA) of all printed colors, except white, shall be not less than 70 % of the values in Table C for Class RA2.
