Understanding ASTM D4956 Type VI Standard
ASTM D4956 is a comprehensive specification that outlines the requirements for retroreflective sheeting used in traffic control applications. Type VI, as defined in the standard, refers to an elastomeric, high-intensity retroreflective sheeting without adhesive, typically made of vinyl microprismatic retroreflective material. This type is specifically intended for temporary roll-up signs, warning signs, traffic cone collars, and post bands, providing high visibility under various lighting conditions.
Detailed Parameters and Data
The performance requirements for Type VI sheeting are rigorous, with a focus on reflectivity and durability. The minimum coefficient of retroreflection (RA) for Type VI sheeting varies by color and angle, with specific values provided in the standard. For instance, the RA values for fluorescent yellow-green at a 0.2° observation angle and -4° entrance angle is 600 cd/fc/ft², while for fluorescent orange it's 450 cd/fc/ft². These values ensure that signs remain visible and legible, even in low-light conditions.
Advantages of ASTM D4956 Type VI Reflective Roll Up Sign Vinyl
High Visibility: With a minimum coefficient of retroreflection ranging from 190 to 750 cd/fc/ft² depending on color and angle, Type VI sheeting ensures optimal visibility for drivers.
Durability: Designed to withstand outdoor weathering for six months as per ASTM D4956, Section 6.4, without significant degradation in reflectivity.
Ease of Use: The non-adhesive backing allows for easy rolling and storage, without causing damage to the retroreflective properties.
Versatility: Available in colors like fluorescent yellow-green, fluorescent yellow, and fluorescent orange, suitable for a variety of temporary signage needs.
Compliance: Adherence to ASTM D4956 standards ensures that the product meets the required safety and performance benchmarks for traffic control applications.
