ASTM D4302-14(2021) - 1.11.2021
 
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.

 
1. Scope

1.1?This specification establishes requirements for composition, physical properties, performance, and labeling of artists oil, resin-oil, and alkyd paints.

1.2?This specification covers pigments, vehicles, and additives. Requirements are included for pigment identification, lightfastness, consistency, and drying time.

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.

1.5?This pertains only to the test method found in Section 8. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
