8、0-C12:1994 ii BSI 12-1999 National foreword This Part of BS 5350 has been prepared under the direction of the Adhesives Standards Policy Committee. It is identical with ISO 11339:1993 Adhesives 180 peel test for flexible-to-flexible bonded assemblies (T-peel test). ISO 11339 was produced as a result
9、 of international discussion in which the UK took an active part. This Part of BS 5350 supersedes BS 5350-C12:1979, which is withdrawn. The Technical Committee has reviewed the provisions of ISO 291:1977, ISO 4588:1989 and ISO 10365:1992, to which normative reference is made in the text, and has dec
10、ided that they are acceptable for use in conjunction with this standard. A British Standard does not 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 i
11、mmunity from legal obligations.

N
14、OTE 1This method was originally developed for use with metal adherends, but other flexible adherends may also be used. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publica
15、tion, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain register
16、s of currently valid International Standards. ISO 291:1977, Plastics Standard atmospheres for conditioning and testing. ISO 472:1988, Plastics Vocabulary. ISO 4588:1989, Adhesives Preparation of metal surfaces for adhesive bonding. ISO 10365:1992, Adhesives Designation of main failure patterns. 3 De
17、finitions For the purposes of this International Standard, the definitions given in ISO 472 and the following definitions apply. 3.1 peel strength force per unit width necessary to bring an adhesive joint to the point of failure and/or maintain a specified rate of failure by means of a stress applie
18、d in a peeling mode ISO 472 3.2 flexible adherends adherends having dimensions and physical properties that permit bending through any angle up to 90 without breaking or cracking 4 Principle For the 180 T-peel test for a flexible-to-flexible assembly, the force is applied to the unbonded ends of the
19、 specimen. The angle between the bond line and the direction of the applied force is not fixed. Adherends are separated at an approximately steady rate from an open edge of a prepared bond, so that separation occurs progressively along the bond line. 5 Apparatus 5.1 Tensile testing machine1), capabl
20、e of maintaining a predetermined constant crosshead rate (preferred rate 100 mm/min). It shall be provided with a suitable self-aligning grip to hold the specimen. Each set of jaws of the grip shall firmly engage the outer 25 mm of one of the unbonded ends of the flexible adherend. The grip and atta
21、chments shall be constructed in such a way that they will move into alignment with the specimen as soon as the force is applied. The machine shall produce a chart that can be read in terms of millimetres of crosshead movement as a function of the applied force. The machine shall permit the measureme
22、nt and recording of the applied force with an accuracy of 2 %. All equipment shall be calibrated regularly. It is recommended that inertia-free equipment be used for this test. 5.2 Device for measuring thickness, with an accuracy of 0,01 mm or a means of controlling the thickness to that tolerance.
23、6 Test specimens 6.1 Test specimens of the dimensions shown in Figure 1 shall be prepared, either individually or cut from bonded laminates. Individual test specimens shall consist of two flexible adherends properly prepared and bonded together. 6.2 Surface treatment shall be such as to obtain optim
24、um strength in the bonded assembly. The preparation of the surface shall be in accordance with either the adhesive manufacturers instructions or ISO 4588 in the case of metal substrates, and the preparation shall be stated in the test report. The adhesive shall be applied in accordance with the manu
