The specification requires manufacturers to submit detailed documentation, including pre-qualification requests, 50-lb samples of each color for testing, and comprehensive product literature. Manufacturers must meet strict technical requirements, such as specific percentages of binders, pigments, and glass traffic beads, precise color coordinate specifications for white, yellow, and black materials, and compliance with environmental and performance standards.
