This European Standard defines terms used in the adhesive industry and terms relating to adhesives in those industries that use adhesives. The terms defined have been classified so that, as far as possible, related concepts (adhesives, functional adhesive components, chemical base products, adherents, adhesives properties, bonding, and bond properties) are grouped together. All definitions are numbered and an alphabetical index which includes all terms is provided at the end of this European Standard. The numbering of the individual definitions is the same in all three versions (English, French and German) of this European Standard. Consequently this European Standard can be used as a dictionary, combined with one or both of the other versions as an aid for translation of terms into French or German, as a source of information about related concepts in the adhesive industry or to provide a term for a concept.
