ENISO10365 was produced as a result of international discussion in which the United Kingdom participated. A British Standard does not
8、 purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside fr

18、 10365:1995 BSI 11-1999 3 1 Scope This International Standard specifies the designations for the main types of failure pattern of bonded assemblies and illustrates, through diagrams, their respective appearances. It applies to all mechanical tests performed on a bonded assembly, regardless of the na
19、ture of the adherends and adhesive which make up the assembly. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are
20、subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 472:1988, P
21、lastics Vocabulary. 3 Definitions For the purposes of this International Standard, the following definitions, taken from ISO472:1988, apply. 3.1 assembly (for adhesives) a group of materials or parts, including adhesive, which have been placed together for bonding or which have been bonded together
22、3.2 adhesion failure; adhesive failure rupture of an adhesive bond in which the separation appears visually to be at the adhesive/adherend interface 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 Ap
23、plication The designation of the failure patterns is provided to classify failures in order to understand better the result of any mechanical test of adhesion on a bonded assembly, which is usually expressed by quantitative measured values. The failure patterns are designated in accordance with the
24、illustrations inTable 1.EN ISO 10365:1995 4 BSI 11-1999 Table 1 Designation of failure patterns Substrate Failure patterns Designation SF Failure of one or both adherends (Substrate failure) CSF Failure of an adherend (Cohesive substrate failure) DF Failure through delamination (Delamination failure
25、) Adhesive Types of cohesion failure Cohesion failure CF Special cohesion failure SCF AF Adhesion failure ACFP Adhesion and cohesion failure with peelEN ISO 10365:1995 BSI 11-1999 5 If more than one type of failure occurs, an approximate percentage for each type of failure pattern shall be given aft
26、er each designation (seeFigure 1). If a delamination failure occurs (i.e.the coating tears off the adherend), the designation (DF) shall be followed by the nature of the coating. NOTE 1Types of coating include primer, varnish, paint, phosphatization, etc. When an oscillating failure of two patterns
27、occurs, it is indicated by adding “OSC” after the description of the failure patterns: AF (50%) + CF (50%), OSC NOTE 2The slip-stick mode of oscillating failure is typical of a system constituted by an elastic adherend and an adhesive which may undergo a transition between different failure mechanis
28、ms (cohesion and adhesion failure or ductile and brittle-cohesion failure), elastic energy being periodically stored and released by the adherend. Figure 2 illustrates a typical pattern of oscillating cohesion and adhesion failure. Examination of the surface using a suitable instrument may enable th
29、e different types of failure pattern to be better distinguished.
