ASTM D 4175:2024

1.1 This terminology standard covers the compilation of terminology developed by Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, except that it does not include terms/definitions specific only to the standards in which they appear. 1.1.1 The terminology, mostly definitions, is unique to petroleum, petroleum products, lubricants, and certain products from biomass and chemical synthesis. Meanings of the same terms outside of applications to petroleum, petroleum products, and lubricants can be found in other compilations and in dictionaries of general usage. 1.1.2 The terms/definitions exist in two places: (1) in the standards in which they appear and (2) in this terminology standard. The compilation is done by a program that pulls the terms and definitions from the Definitions section (usually 3.1) of each published D02 standard. Recently the program has run in early Fall of each year. See X1.1.4 for further information. 1.1.2.1 ASTM recognizes a second type of definition, Definitions Specific to This Standard. See X1.3.2 . These definitions are not included in the terminology standard. 1.2 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.
