ASTM D 4800 : 1994 : R2023

1.1This guide provides a classification system for tabulating the properties of adhesives suitable for holding parts or assemblies together. The use of this guide also provides information necessary for the development of standard specifications for adhesives.

1.2Limitations—This classification system is intended to be a means of identifying adhesives. It is not intended for the selection of materials. Material selection should be made by those having expertise in the adhesives field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the attachment process to be employed, the inherent properties of the material not covered in this document, and the economic factors.

1.3This classification system is based on the premise that adhesives can be arranged into broad generic families using basic properties to arrange the materials into groups, classes, and grades.

1.4In all cases where the provisions of this classification system would conflict with the referenced ASTM specification for a particular material, the latter shall take precedence.

1.5The values stated in SI units, as detailed in IEEE/ASTM SI 10, are to be regarded as the standard.

1.6This 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.
