Significance and Use | ||||||||||||||||||||
This specification establishes quality requirements and provides a basis for common understanding among producers, distributors, and users. 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. |
