Standard Specification for Artists' Colored Pencils
SCOPE
1.1 This specification establishes requirements for composition, performance, and labeling of artists' colored pencils.
1.2 This specification covers vehicles and additives. Requirements are included for identification, lightfastness, and consistency.
1.3 Colored pencil specimens are exposed to both natural daylight through window glass and simulated window glass-filtered daylight radiation to determine the lightfastness rating for each pencil.
