1.1 This specification covers flexible, non-exposed glass bead lens and microprismatic, retroreflective sheeting designed for use on traffic control signs, delineators, barricades, and other devices. This specification covers the performance of retroreflective sheeting materials and does not specifically address inks, overlays, or other imaging methods that may be applied to retroreflective sheeting material to create traffic signs or other devices. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 The following safety hazards caveat pertains
only to the test methods portion, Section 7, of this specification.
