21、(E) 4 Introduction This European Standard is intended for characterisation of plastic and rubber sheets as manufactured or supplied before use. This test method relates to products, or to their components where appropriate, and not to waterproofing membrane systems composed of such products and inst
22、alled in the works. This test is intended to be used in conjunction with European Standards for plastic and rubber sheets for waterproofing. DIN EN 12316-2:2013-08 EN 12316-2:2013 (E) 5 1 Scope This European Standard specifies a method for determining the resistance to peeling of joints between two
23、adjacent sheets of the same plastic or rubber sheets for waterproofing. This test method will be used mainly for testing the joints in mechanically fastened plastic or rubber sheets for waterproofing. The peel strength characterises the optimum joint strength which can be reached for a membrane and
24、a joint technique under laboratory conditions. On roofs the joint strength could be clearly reduced due to the non-optimal conditions (e.g. pressure, temperature, humidity, pollution, workmanship). The requirement for the joint technique at the site is to ensure a permanently tight joint. 2 Normativ

27、proofing Rules for sampling 3 Terms and definitions For the purpose of this document, the following terms and definitions apply. 3.1 peel resistance tensile force required to completely separate a prepared joint test specimen by peeling 4 Principle The principle of the test is to pull a test specime
28、n to peel a joint at a constant speed until it breaks. The tensile force is continuously recorded throughout the test. 5 Apparatus Tensile testing machine equipped with a continuous recording of force and corresponding extension and capable of maintaining uniform speed of grip separation as specifie
29、d below. Tensile testing machine shall have a sufficient loading capacity and a grip separation speed of (100 10) mm/min. The width of grips shall not be less than 50 mm. The tensile testing machine shall be equipped with grips of a type which maintain or increase the clamping pressure as a function
30、 of the increase of the force applied to the test specimen. The test specimen shall be held so that it does not slip in the grips more than 2 mm. DIN EN 12316-2:2013-08 EN 12316-2:2013 (E) 6 The method of gripping shall not induce premature rupture close to the grips. The force measuring system shal
31、l meet at least Class 2 of EN ISO 7500-1 (i.e. 2%). 6 Sampling Samples shall be taken in accordance with EN 13416.

32、Peel strength testing of side and end laps DIN EN 12316-2:2013-08 EN 12316-2:2013 (E) 7 7 Preparation of test pieces and test specimens Test pieces of the sheet are joined by the method(s) to be used for installation as recommended by the manufacturer. After jointing, the test piece shall be conditi
33、oned for a minimum of 16 h at (23 2) C before testing unless the manufacturer recommends differently. From each of these joint test pieces, five rectangular test specimens (50 1) mm wide shall be cut, perpendicular to the joint (see Figure 1). They shall have such a length, that the ends of the spec
34、imen fill the grips and that the complete overlap can be tested perpendicular to joint (see Figure 2). Rectangular joint test specimens shall be prepared representing all possibilities of jointing according to the way(s) to be used for installation. The number of specimens tested is five per set. 8
35、Procedure The test specimen shall be firmly held in the grips of the tensile testing machine, taking care that the longitudinal axis of the test specimen, the axis of the tensile testing machine and the grips are correctly aligned. The clear distance between the grips shall be (100 5) mm (see Figure
36、 2). No preload will be applied. The test is carried out on a test specimen at a temperature of (23 2) C and at a constant separating speed for the grips of (100 10) mm/min. The applied force and extension shall be recorded continuously until the test specimen separates. The mode of failure of the j
37、oint shall be recorded. The modes of failure are classified in three classes A, B, C or combinations of them (see Figure 3). A - Peeling of the joint B - Break outside of the joint DIN EN 12316-2:2013-08 EN 12316-2:2013 (E) 8 C - Delamination of sheet. In this case the area of delamination has to be
38、 more than 5 % of the joint area. Figure 3 Mode of failure 9 Expression of results 9.1 Jointing information State all relevant information on the formation and the conditioning of the joint. 9.2 Evaluation 9.2.1 General A force extension graph shall be drawn up. Disregard any test result where the t
39、est specimen breaks less than 10 mm from the grips or slips by more than the permitted limit within the grips of the tensile testing machine, and retest with a replacement specimen. The mode of failure of each specimen has to be reported in accordance to Clause 8. An average of all specimens can onl
40、y be calculated if the failure mode is identical for all specimens. If different failure modes occur, only evaluation in accordance to the main failure mode has to be reported. 9.2.2 Maximum peel resistance If a majority of the specimens do not show failure mode A (i.e. a majority of the specimens s
41、how either failure mode B or C or combination of both) and the maximum force detected is more than 100 N/50 mm, then the maximum peel resistance has to be evaluated. In this case, no value for the resistance should be reported. Only the classification “no failure of the joint” has to be reported. Th
42、is is the best possible joint. This evaluation applies if, for a majority of the specimens, “no failure of the joint” occurs. 9.2.3 Average peel resistance (relevant only if peel fully occurs) If a majority of the specimens show failure mode A, then the average peel resistance has to be evaluated. A
43、t least the first and last quarter of the graph shall not be included when calculating the average peel resistance of the test specimen. An average value of the force is calculated on the remaining section by determination of ten equidistant values and is expressed as N/50 mm (see Figure 4). DIN EN
44、12316-2:2013-08 EN 12316-2:2013 (E) 9 Key 1 maximum peel force a points to be evaluated Y force axis X extension axis Figure 4 - Graph for calculating the peel resistance (example) The purpose of the evaluation method specified here is to calculate an average peel resistance value, which corresponds
45、 to the mean value of the forces acting on the test specimen at certain specified times during testing. This method also permits an evaluation to be carried out if the graphs do not feature any distinctive peaks. This can occur when testing some bonded materials. It should be noted that the results
46、could vary, depending on the direction in which the test specimens are taken. 9.3 Calculations If a majority of the specimens show failure mode A then calculate the results for specimens with failure mode A, the peel resistance as the mean (using the maximum or average peel force as occurs for each
47、specimen) expressed in N/50 mm. State the peel resistance to the nearest Newton with the corresponding standard deviation. If the maximum peel resistance is evaluated, no calculation is needed. 9.4 Precision of the test method As estimated by accredited laboratories the scattering due to the uncerta
48、inty in measurement based on a single value evaluation (force, width) is about 10 %. 10 Test report The test report shall include the following information: a) reference to this European Standard (EN 12316-2) and any deviation from it; b) all details necessary to identify the product tested; c) information on sampling in accordance with Clause 6; d) details of preparation of the test specimen in accordance with Clause 7; DIN EN 12316-2:2013-08 EN 12316-2:2013 (E) 10 e) test results in accord
