994-1 Description.
994-1.1 General: This Section specifies the requirements for ret roreflective and
nonreflective sheeting and sign panel materials and fabrication. This includes the sign sh eeting materials such as transparent and opaque process inks for retroreflective sheeting materials , vinyl and transparent overlays.
994-2 Retroreflective and Nonreflective Sheeting Systems .
994-2.1 Materials: Retroreflective sheeting material shall be classified in accordance
with and meet the requirements of ASTM D4956. Overlay materials include colored and colorless transparent overlays and vinyl. Inks include transparent and opaque silkscreen inks as well as inkjet inks used in digital print systems.
994-2.2 Approved Product List (APL): All sheeting, process inks and overlay materials
shall be listed as a system on the Department’s Approved Product List (APL). Sign sheeting systems shall consist of base sheeting wi th ink and/or overlay materials. Products with an ASTM classification of Type XI or greater will not be accepted for qualification on the APL for fluorescent orange. Manufacturers seeking evaluation of their products need to submit product data sheets, per formance test reports from an independent laboratory showing the sign sheeting system meets the requirements of this Section, and a APL application in accordance with Section 6. Information on the APL application shall include the individual materials comp rising the sign sheeting system and identify colors, ASTM base sheeting classification, adhesive backing class, availability of transparent and/or opaque backing and availability of liner type s.
994-2.3 Performance Requirements :
994-2.3 1 General: Sheeting, process inks and overlay materials shall be tested in
accordance with, and meet all the performance requirements of ASTM D4956, including Supplemental Requirement S2, Reboundable Sheeting Requirements , except as amended in this Section. For performance requirements that are color dependent, each color included in the APL application shall be tested and meet the requirements identified in ASTM D4956 or this Section as applicable. All sign sheeting systems consisting of inks and/or overlays will be tested as a system consisting of white base sheeting and each color of ink and/or overlay. Panels for testing sheeting shall be prepared in accordance with 994 -3 for testing. The in -service life for the sign sheeting system shall equal the life of the reflective base sheeting of the system .
994-2.3 2 Retroreflective Intensity: The retroreflectivity of sheeting and
sheeting systems shall meet the minimum initial requirements as stated for all observation and entrance angles as identified in ASTM D4956. The 0.2 and 0.5 degree observation angles with an entrance angle of minus 4 degrees per ASTM D4956 shall be used for in -service requirements. Rotational sensitivity shall be tested in accordance with AASHTO M268. Rotationally sensitive sheeting will be noted on the APL.
994-2.3 3 Clear Overlay Films: Clear overlay film shall be compatible with the
sign sheeting system and not delaminate or dis color for the in -service life of the system. FY 2023-24 Return to Table of Contents
