CEN EN*IS0*10365 95 3404589 OLL25Lt9 O29 E Page 3 EN IS0 10365 Adhesives - Designation of main failure patterns 1 Scope This International Standard specifies the desig- nations for the main types of failure pattern of loonded assemblies and illustrates,
18、 through dia- grams, their respective appearances. It applies to all mechanical tests performed on a bonded assembly, regardless of the nature of the adherends and adhesive which make up the as- sembly. 2 Normative reference The following standard contains provisions which, through reference in this
19、 text, constitute provisions of this International Standard. At the time of publi- cation, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encour- aged io investigate the possibility of applying the most recen
20、t edition of the standard indicated below. Members of IEC and IS0 maintain registers of cur- rently valid International Standards. is0 472:1988, Plastics - Vocabulary. 3 Definltlons For the purposes of this International Standard, the following definitions, taken from IS0 472:1988, apply. 3.1 assemb
21、ly (for adhesives): A group of materials or parts, including adhesive, which have been placed together for bonding or which have been bonded together. 3.2 adhesion failure; adhesive failure: Rupture of an adhesive bond in which the separation appears visually to be at the adhesiveladherend interface
22、. 3.3 cohesion failure; cohesive failure: Rupture of a bonded assembly in which the separation appears visually to be in the adhesive or the adherend. 4 Application The designation of the failure patterns is provided to classify failures in order to understand better the result of any mechanical tes
23、t of adhesion on a bonded assembly, which is usually expressed by quantitative measured values. The failure patterns are designated in accordance with the illustrations in table 1.
