ASTM D6901-06

Standard Specification for Artists' Colored Pencils (Withdrawn 2015)

ABSTRACT
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.
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.
WITHDRAWN RATIONALE
This specification establishes requirements for composition, performance, and labeling of artists’ colored pencils.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this specification was withdrawn in January 2015 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
