1、Designation: D 16 08Standard Terminology forPaint, Related Coatings, Materials, and Applications1This standard is issued under the fixed designation D 16; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision.An

2、umber in parentheses indicates the year of last reapproval.Asuperscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This standard consists of technical terms used in stan-d

3、ards under the jurisdiction of ASTM Committee D01 (onPaint and Related Coatings, Materials, and Applications), andof definitions suitable for use in these standards.NOTE 1When any definition in this standards is quoted or publishedout of the context of this standard, editorially insert the following

4、delimiting statement “for paints and related coatings, materials, andapplications” after the dash following the term (in the absence of anexisting delimiting statement). This will limit the filed of application ofthe term and definition to that approved by this committee.1.2 In this terminology stan

5、dard, definitions used in otherASTM standards are indicated by following the definition withthe designation of that standard. In some cases, a relevant D01subcommittee is also listed. Definitions influenced by thoseused by other organizations are indicated by the acronym of theorganization. Primary

6、terms are given in bold, while narrowerand unapproved terms are given in italics.1.3 There are several specialized terminology standardsunder the jurisdiction of Committee D01, as follows: D 804,D 1695, D 6440, D 6488, and D 7188. Few definitions fromthose standards are included in Terminology D 16.
