This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health
16、 practices and to ensure compliance with any regulatory conditions. It is recognized that some of the materials permitted in this document may have a negative environmental impact. As technological advances lead to more acceptable alternatives for such materials, they will be eliminated to the great
17、est extent possible. At the end of the test, care should be taken to dispose of all waste in an appropriate manner in accordance with local regulations. 1 Scope This International Standard specifies a T-peel test for the determination of the peel strength of an adhesive by measuring the peeling forc
18、e of a T-shaped bonded assembly of two flexible adherends. This test procedure does not provide design information. NOTE This method was originally developed for use with metal adherends but other, flexible, adherends may also be used. 2 Normative references The following referenced documents are in

21、essary to bring an adhesive joint to the point of failure and/or maintain a specified rate of failure by means of a stress applied in a peeling mode ISO 472:1999 BS EN ISO 11339:2010ISO 11339:2010(E) 2 ISO 2010 All rights reserved3.2 flexible adherend adherend having dimensions and physical properti
22、es that permit bending through any angle up to 90 without breaking or cracking 4 Principle For the T-peel test for a flexible-to-flexible assembly, the force is applied to the unbonded ends of the specimen. The angle between the bond line and the direction of the applied force is not fixed. Adherend
23、s 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), capable of maintaining a predetermined constant crosshead rate (preferred rate 100 mm/min). It shall be provide
24、d 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 the unbonded ends of the flexible adherends. The grip and attachments shall be constructed in such a way that they will move into alignment with the specimen as soon as the
25、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 measurement and recording of the applied force with an accuracy of 2 %. All equipment shall be calibrated regularly. It
26、is recommended that a clamping device with low inertia be used. 5.2 Device for measuring thickness, with an accuracy of 0,01 mm, or a means of checking the thickness to that tolerance. 6 Test specimens 6.1 Test specimens of the dimensions shown in Figure 1 shall be prepared, either individually or c
27、ut from bonded laminates. Test specimens shall consist of two flexible adherends properly prepared and bonded together. 6.2 Surface treatment shall be such as to obtain optimum strength in the bonded assembly. The preparation of the surface shall be in accordance with ISO 17212, and details of the p
28、reparation shall be stated in the test report. The adhesive shall be applied in accordance with the manufacturers instructions to obtain an optimum bond with minimum variation; the procedure used shall be reported in the test report. NOTE Direct comparison of different adhesives can be made only whe
29、n specimen construction, adherend materials and dimensions, and test conditions are identical. 6.3 The thickness of the flexible adherends shall be reported. The preferred thicknesses are 0,5 mm 0,02 mm for steel (type XES)2)and 0,7 mm 0,02 mm or 0,5 mm 0,02 mm for aluminium (type 5754, H111)3)unles
30、s otherwise specified. 1) See for instance ISO 58934. 2) XES = low-carbon steel: composition (in mass %) C = 0,05, Cr 0,01, Cu = 0,013, Mn = 0,018, Al = 0,064, Ni = 0,02; Youngs modulus E = 210 GPa; initial yield stress y= 150 MPa; strain-hardening coefficient = 0,4. 3) See ISO 2091and ISO 21073.

31、 EN ISO 11339:2010ISO 11339:2010(E) ISO 2010 All rights reserved 36.4 Test specimens shall be cut from the bonded panels (see Figure 1) by a method that is not deleterious to the bond. The width shall be either a) 25 mm (preferred width) or b) any other convenient width, provided that the test equip
32、ment is suitably adapted and the width is stated in the test report. NOTE The method of cutting the specimens is dependent upon the adherend and adhesive compositions and the specimen width tolerance specified in Figure 1. Milling and bandsawing are two methods commonly used for this purpose. 6.5 Be
33、fore the test is carried out, the test specimen shall be bent in a manner that does not affect the bonded joint. The two unbonded ends of the flexible adherends shall be bent in opposite directions until each end is perpendicular to the bonded assembly, to form a T-shaped specimen (see Figure 1) for
34、 clamping in the grips of the test machine. 6.6 The number of specimens tested shall be not less than five. 6.7 The specimens shall be conditioned and tested in one of the standard laboratory atmospheres specified in ISO 291, which shall be reported in the test report. 7 Procedure On the at least fi
35、ve specimens, using the device described in 5.2, measure with an accuracy of 0,01 mm the average thickness of the adhesive layer after formation of the bond. Clamp each unbonded end of the T-shaped specimen in the grips of the test machine, taking care that the end is accurately aligned between the
36、grips so that the tension applied is distributed evenly across the width. If one adherend is more flexible than the other, attach the less flexible adherend to the moveable grip. Set the machine in motion at the selected separation rate and record the force applied versus the distance of grip separa
37、tion. NOTE A separation rate of 100 mm/min is generally used for metals and 10 mm/min for other adherends. Continue the test until at least 150 mm of the bonded length is separated. Note the type of failure in accordance with ISO 10365. BS EN ISO 11339:2010ISO 11339:2010(E) 4 ISO 2010 All rights res

Figure 1 Panel before cutting and individual specimen after cutting 8 Expression of results Determine from the recorded curve, for about 100 mm of peeling (disregarding the first 25 mm
39、and the last 25 mm), the average, maximum and minimum peeling force, in newtons, required to separate the adherends. The average force shall be determined from the curve by drawing the best straight line, or by using other suitable means if a more accurate result is required. Record the average, max
40、imum and minimum peeling forces for each individual specimen. From the peeling forces thus recorded, calculate the average, maximum and minimum peel strengths for each individual specimen, in newtons per 100 mm of specimen width. 9 Precision The precision of this test method is not known because int
