913Reflectorizing Materials

913.1 General Description

This section includes the requirements for reflective sheeting.

913.1.01 Definitions

• Reflective Sheeting Types: Type I: Medium-intensity retroreflective sheeting (engineering grade) that is typically an enclosed lens glass-bead retroreflective material. Type II: Medium-high-intensity retroreflective sheeting (super engineering grade), that is typically enclosed lens glass-bead retroreflective material. Type III: High- intensity retroreflective sheeting that is typically an encapsulated glass-bead retroreflective material or an unmetalized microprismatic retrotreflective element material. Type IV: High- intensity retroreflective sheeting that is typically an unmetallized microprismatic retroreflective element material. Type V: Super-high-intensity retroreflective sheeting that is typically a metallized microprismatic retroreflective element material. This material is typically used for delineators. Type VI: Elastomeric high-intensity retroreflective sheeting without adhesive that is typically a vinyl microprismatic retroreflective material. This material is typically used for orange temporary roll up signs. Type VII: Super-high-intensity retroreflective sheeting that is typically an unmetallized microprismatic retroreflective element material. Type VIII: Super-high-intensity retroreflective sheeting that is typically an unmetallized microprismatic retroreflective element material. Type IX: Very-high-intensity retroreflective sheeting that is typically an unmetallized microprismatic retroreflective element material. Type X: Super-high intensity retroreflective sheeting that is typically an unmetallized microprismatic retroreflective elemnt material. Type XI: Very-high-intensity retroreflective sheeting that is typically an unmetalized cube corner microprismatic retrotreflective element material.

913.2.01 Type I, II, III, IV, V, VI, VII, VIII, IX, X, and XI Reflective Sheeting

A. Requirements 1. Use reflective sheeting that meets the requirements of ASTM D 4956. 2. Use reflective sheeting as listed in QPL 29. 3. Use reflective sheeting that has been evaluated by the National Transportation Product Evaluation Panel (NTPEP) test facility or other approved test facility. 4. Submit the following to the Department: a. A certificate with each lot or shipment stating the following: • The material supplied will meet all the test requirements listed herein. • You have performed the specified tests to ensure compliance. • You will submit test results upon request. B. Fabrication General Provisions 101 through 150. C. Acceptance 1. The Engineer will reject reflective sheeting in the following situations: a. The material fails to meet any one of the designated requirements. b. The material meets the requirements but later fails during sign fabrication or in actual field use. Cracks, wrinkles, delamination, color change, or abnormal loss of reflectivity constitute failure. c. Natural causes deteriorate the material to the extent that: 1) The sign is ineffective for its intended purpose as defined in Subsection 913.2.01.C.1.b above. 2) The average nighttime reflective brightness does not meet the outdoor weathering requirements of ASTM D 4956. D. Materials Warranty Transfer to the Department a performance warranty for Type I, II, III, IV, V, VI, VII, VIII, IX, X, or XI reflective sheeting issued by the manufacturer. Ensure that the warranties cover the full replacement cost, including material and labor. Include in these warranties a provision that the warranty is subject to a transfer to the Department. Submit a warranty from the manufacturer that states that the reflective sheeting—processed, applied to sign blank materials, and cleaned—meets the outdoor weathering photometric requirements of ASTM D 4956.
