Attachment 5 Validation Sheeting Colors and Reflective Characteristics.pdf

This is a technical specification attachment for validation stickers and registration materials procured by the Missouri Department of Revenue. The document establishes retroreflective characteristics and color standards for validation sheeting used on annual license plate registration stickers distributed to Missouri citizens. The specification requires that the coefficient of retroreflection be measured on flat, clean validation sheeting and meet minimum values at a 0.2-degree observation angle, with measurements conducted according to ASTM E-810 standards.

The validation sheeting must meet specific retroreflective performance requirements across ten color options: white, yellow, purple, green, blue, red, orange (neon), black, lime green, and pink (neon). Each color has defined entrance angle specifications at 4 degrees, 40 degrees, and 50 degrees, with corresponding minimum candlepower per foot-candle per square foot values. The specification ensures that registration stickers maintain adequate visibility and retroreflective properties for identification purposes across varying lighting and observation conditions.
