ASTM D 333 : 2001 : R2021

Note 1:In accordance with Terminology D16, a lacquer is defined as a coating composition that is based on synthetic thermoplastic film-forming material dissolved in organic solvent(s) and that dries primarily by solvent evaporation. Typical lacquers include those based on nitrocellulose, other cellulose derivatives, vinyl resins, acrylic resins, etc.

Note 2:Lacquers may be applied under such diverse conditions, to so many different surfaces, and their dried films may be subjected to so many kinds of wear and exposure that it is not possible to assure desired performance from a single selection of test methods and numerical results therefrom. Those skilled in lacquer technology may find partial assurance of obtaining desired qualities in various types of lacquers through careful selection of the methods covered herein and intelligent interpretation of results therefrom.

Note 3:It is intended ultimately to remove all experimental procedures from Test Methods D333 and to establish them as a guide to the selection of test methods for lacquer and perhaps to interpretation of results therefrom. Temporarily there remain in Test Methods D333 a few tests that are too short or otherwise presently unsuitable for establishment under separate ASTM designations.
