Standard Specification for Artists' Watercolor Paints
ABSTRACT
This specification establishes requirements for composition, physical properties, performance, and labeling of artists' watercolor paints. Lightfastness determination, exposure tests, and mean color difference calculation shall be conducted to meet the specified requirements.
SCOPE
1.1 This specification establishes requirements for composition, physical properties, performance, and labeling of artists' watercolor paints.
1.2 This specification covers pigments, vehicles, and additives. Requirements are included for pigment identification, lightfastness, and consistency.
1.3 Table 1 lists some pigments meeting the lightfastness requirements in this specification. In order to identify other pigments that meet these requirements, instructions are given for test specimen preparation. Test methods for determining relative lightfastness are referenced.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
