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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
