Attachment 5 Validation Sheeting Colors and Reflective Characteristics.pdf

This is a technical specification attachment establishing validation sheeting retroreflective characteristics standards for a state or local contract opportunity. The document specifies minimum coefficient of retro-reflection values that validation sheeting must meet, measured at a 0.2 degree observation angle and expressed in candelas per lux per square meter. Testing must be conducted in accordance with ASTM E-810, "Standard Test Method for Coefficient of Retro-reflection of Retro-reflective Sheeting," on flat, clean material samples. The specification includes retroreflective performance requirements across multiple colors at three entrance angles: -4 degrees, 40 degrees, and 50 degrees. Color requirements are provided for white, yellow, purple, green, blue, red, orange (neon), black, lime green, and pink (neon) sheeting.

The document establishes minimum candlepower performance thresholds that vary by color and entrance angle, with white sheeting requiring the highest retroreflection values (50, 15, and 30 candelas per lux per square meter at the respective angles) and black sheeting requiring the lowest values (6, 2, and 3 candelas per lux per square meter). These specifications ensure that validation sheeting meets established retroreflective standards necessary for visibility and safety applications. The attachment does not contain pricing information, award dates, contract terms, or other administrative details related to the procurement opportunity.
