The
19、 work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gove
20、rnmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. T
21、he main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vot
22、e. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8510-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

25、-to-rigid test specimen assembly Part 2: 180 peel SAFETY PRECAUTIONS Persons using this document should be familiar with normal laboratory practice, if applicable. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the u
26、ser to establish appropriate safety and health practices and to ensure compliance with any regulatory conditions. 1 Scope This part of ISO 8510 specifies a 180 peel test for the determination, under specified conditions, of the peel resistance of a bonded assembly of two adherends where one adherend
27、 is flexible and the other is rigid. A 90 peel test, more suitable for use with less flexible adherends that crack, break or delaminate in the 180 peel test, is described in ISO 8510-1. 2 Normative references The following referenced documents are indispensable for the application of this document.
28、For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、f metals and plastics prior to adhesive bonding 3 Principle A bonded assembly of two adherends is prepared using the adhesive under test. The adherends are then pulled apart at a substantially steady rate, starting at the open end of the bond, in such a way that separation occurs progressively along
30、 the length of the bonded adherends. The force is applied substantially parallel to the plane of the bond, through the separated part of the flexible adherend. 4 Apparatus 4.1 Tensile testing machine, capable of supplying a tensile force with a constant rate of grip separation. The machine shall be
31、equipped with a force-measuring system complete with an indicator and/or a recorder. The indicated force shall not differ from the true applied force by more than 2 %. The response time of the machine shall be short enough not to affect the accuracy with which the force applied at the time of ruptur
32、e can be measured. The force at rupture of the specimen shall lie in the range between 10 % and 80 % of the full-scale reading.

33、 Grips, one of which shall be suitable for firmly clamping the rigid adherend (5.1.2) so that the plane of the bond is parallel to the applied force, while the other shall be suitable for holding the flexible adherend (5.1.3), as shown in Figure 1. The latter grip shall be self-aligning, so that the
34、 force will be exerted parallel to the plane of the bond, and linked to the sensor of the tensile testing machine (4.1). 5 Test specimens 5.1 Adherends 5.1.1 General The adherends shall be thick enough to withstand the expected tensile force and their dimensions shall be measured accurately and repo
35、rted in full in the test report. The recommended thicknesses of test specimens are: metals 1,5 mm; plastics 1,5 mm; wood 3 mm; compounded rubbers 2 mm. Other thicknesses agreed on between the purchaser and the supplier of the adhesive may be used. 5.1.2 Rigid adherend The rigid adherend shall consis
36、t of a strip of flat material of width 25,0 mm 0,5 mm and minimum length 200 mm. 5.1.3 Flexible adherend The flexible adherend shall be capable of being bent through an angle of 180 without gross irreversible dimensional change. Unless specified otherwise, the flexible adherend shall be not less tha
37、n 350 mm in length. Its width shall be either a) the same width as the rigid adherend, or b) for materials prone to fraying, e.g. cotton duck, 5 mm wider at each edge. NOTE Flexible adherends may cause difficulties in test specimen assembly and give rise to a greater dispersion of results than would
38、 otherwise be the case, because of distortion or fraying of the weave during assembly and testing. The use of a flexible adherend 5 mm wider at each edge than the rigid adherend is designed to reduce these effects. 5.2 Preparation of test specimens The procedure used in preparing the test specimens
39、shall be such as to minimize variations. The use of a pneumatic or hydraulic press, hand or power-operated, that can apply a pressure of up to 1 MPa, is recommended. Surface treatments shall be in accordance with ISO 17212, or, if this is not feasible, in accordance with the manufacturers instructio
40、ns. Apply the adhesive, in accordance with the manufacturers instructions, over the whole width of the adherends to a length of 150 mm on each adherend. NOTE A convenient method of obtaining a sharp adhesive boundary is to place a thin strip of material to which the adhesive does not adhere (anti-ad
41、hesive strip) at the end at which separation of one of the adherends will commence (see Figure 1). Allow the adhesive to set and, if necessary, cure it, in accordance with the manufacturers instructions. Bond the adherends using the method recommended by the manufacturer of the adhesive.

43、bly be fitted with a timer-controlled release mechanism. In order to provide a uniform distribution of pressure over the bonded area, the platens of the press shall be parallel. When this is impracticable, one platen shall be covered with a resilient pad. A 10 mm thick pad of rubber of Shore A hardn
44、ess approximately 45 has been found to be satisfactory, using a press that applies a pressure of up to 700 kPa. As an alternative to preparing individual test specimens, panels of suitable size may be bonded to each other and test specimens cut from the bonded assembly, discarding from the bonded as
45、sembly the 12 mm strip along each of the outer edges parallel to the longer sides of the test specimens. Determine the average thickness of the applied adhesive as accurately as practicable, by weighing or another suitable technique. 5.3 Number of test specimens A minimum of 5 specimens shall be tes
46、ted. 6 Conditioning and testing atmosphere The test specimens shall be conditioned and tested in one of the standard atmospheres specified in ISO 291. 7 Procedure Bend back the unbonded end of the flexible adherend. Clamp the rigid adherend in the fixed grip and the flexible adherend in the other gr
47、ip, taking care that the test specimen is accurately positioned between the grips so that the tension applied is distributed uniformly across the width of the test specimen (see Figure 1). Set the machine in motion at a constant rate of grip separation. The recommended rate of grip separation is 100
48、 mm/min 10 mm/min. If this is not practicable, other rates may be agreed on between the purchaser and supplier of the adhesive. Record the rate of grip separation. Also record the force as a function of grip separation, preferably autographically. Continue the test until at least 125 mm of the bonde
49、d length has separated. Note the type of failure, i.e. adhesive failure, cohesive failure or adherend failure. NOTE The peeled part of the flexible adherend will rub on the adhering part as separation progresses. To reduce friction, a suitable lubricant, such as glycerol or soap solution, may be used, provided it does not affect the adherends. 8 Expression of results For each specimen, determine from the curve of force versus grip separation, the average peel force in newtons, over a peel length of at least
