ASTM D5067-16

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.
SIGNIFICANCE AND USE
4.1 This specification establishes quality requirements and provides a basis for common understanding among producers, distributors, and users.  
4.2 It is not intended that all paints meeting the requirements be identical nor of uniform excellence in all respects. Variations in manufacture, not covered by this specification, may cause some artists to prefer one brand over another, either of which may be acceptable under this specification.
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 SI units are to be regarded as standard. The values given in parentheses are for information only.
