20、5:2006iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for

21、which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on al

22、l matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are

23、circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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 res

24、ponsible for identifying any or all such patent rights. ISO 13445 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products. This second edition cancels and replaces the first edition (ISO 13445:1995), which has been technically revised. EN ISO 13445:20061Adhesives Determ

25、ination of shear strength of adhesive bonds between rigid substrates by the block-shear method 1 Scope This International Standard specifies a method for the determination of the shear strength of adhesives used to bond materials with elastic moduli higher than the elastic modulus of the adhesive. T

26、he method provides an estimate of the shear strength of an adhesive on various machinable and non-machinable substrate materials. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. Fo

The method is particularly applicable to the testing of bonds between ceramic parts, glass parts, magnet mouldings and plastic parts having one f

The machine shall conform to the requirements of ISO 7500-1. 5.2 Shearing fixture, consisting of a specimen-holding block and a shearing tool (see F

32、igures 1 and 2). Adherends measuring up to 80 mm 80 mm 13 mm can be held in the block, while the shearing tool can be used with adherends measuring up to 30 mm 30 mm 13 mm. A test specimen with adherends approximating to these dimensions is shown in Figure 3a). For test specimens having two smaller

33、adherends as shown in Figure 3b), an adapter plate can be inserted into the specimen-holding block (see Figure 4) to keep the shearing tool in its guides and to ensure the specimen is located under the clamp.

EN ISO 13445:20064 NOTE 1 Other adherend dimensions, within the limits of the shearing-fixture capacity

36、, may be used depending on the application, provided the specimens are thick enough to avoid deformation occurring. NOTE 2 This method is not applicable to thin adherends with which deformation of the specimen would occur. 6.2 Prepare the surface of the specimen in accordance with EN 13887. 6.3 Prep

37、are the adhesive and apply it in accordance with the adhesive manufacturers recommendations. Bond the adhesive-coated adherends in accordance with the procedure under investigation. Assemble straight-sided adherends such that the thrust surfaces of the specimen are parallel to within 5 m/mm. Determi

38、ne the thickness of the adhesive layer to within 0,02 mm using suitable equipment. 6.4 Remove immediately any excess adhesive squeezed out during assembly. Figure 3 shows typical specimens after bonding. 6.5 Test a minimum of five specimens. 7 Conditioning The specimens shall be conditioned and test

39、ed in one of the standard conditioning atmospheres specified in ISO 291. 8 Procedure 8.1 Mount the shearing fixture in the test machine with the specimen-holding block on top. 8.2 Place an assembled specimen in the shearing fixture in such a way that one of the adherends is held by the holding block

40、 and the other engaged by the shearing tool (see Figure 5). Centre the specimen in the shearing tool so that no turning moment is applied to the specimen during shearing. Close the toggle clamp on the rear of the specimen-holding block to keep the specimen (or adapter) located against the shearing t

41、ool. 8.3 Test the specimen using a crosshead speed of 1,5 mm/min. Record the maximum force sustained by the specimen. 8.4 Examine the adherends after the test to determine the failure pattern in accordance with ISO 10365. 8.5 Repeat the procedure for the remaining specimens. 9 Expression of results

42、Calculate the maximum shear stress for each specimen by dividing the maximum force by the bond area. Average the maximum shear stresses for all replicates to determine the average shear strength. Express the shear stress and shear strength in megapascals. 10 Precision The precision of this test meth

43、od is not known because interlaboratory data are not available. When inter-laboratory data are obtained, a precision statement will be added at the following revision. 11 Test report The test report shall include the following information: a) a reference to this International Standard; b) all detail
