This standard specification establishes quality requirements for composition, performance, and labeling of artists´ colored pencils. This specification also covers vehicles and additives. Labeling requirements shall include company or brand name, identification number, country of origin, colour index names, lightfastness, pencil type, name and address of manufacturer, constitution number, toxicity, and statement of conformance. Additives for colored pencils shall include thickeners, preservatives, surfactants, wax, oil, and humectants. The pencil shall be capable of applying an even coating without scratch marks and without excessive breaking. Lightfastness, color difference test, exposure to natural daylight through window glass, and exposure to Xenon-arc radiation shall be done in accordance with the ASTM standard testing method using white, uncoated, neutral pH, buffered paper or board, without optical brighteners.
