DIN EN 12317-2:2010-12 EN 12317-2:2010 (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 comp
22、onents where appropriate, and not to waterproofing membrane systems composed of such products and installed in the works. This test is intended to be used in conjunction with EN 13956, Flexible sheet for waterproofing Plastic and rubber sheets for roof waterproofing Definitions and characteristics.
23、DIN EN 12317-2:2010-12 EN 12317-2:2010 (E) 5 1 Scope This European Standard specifies a method for determining the resistance to shearing of joints between two adjacent sheets of the same plastic or rubber sheets for roof waterproofing. NOTE The shearing characteristics of a joint between two widths
24、 of plastic or rubber sheets vary considerably depending on the material, method of jointing, the size of the overlap and the workmanship. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited ap
25、plies. For undated references, the latest edition of the referenced document (including any amendments) applies.

26、testing machines Part 1: Tension/ compression testing machines Verification and calibration of the force-measuring system (ISO 7500-1:2004) 3 Terms and definitions For the purposes of this document, the following term and definition apply. 3.1 shear resistance maximum tensile force required to exten
27、d a prepared joint test specimen, in shear, until it breaks or separates 4 Principle The principle of the test is to pull a specimen of a joint in shear at a constant speed until it breaks or separates. The tensile force is continuously recorded throughout the test. 5 Apparatus Tensile testing machi
28、ne equipped with a continuous recording of force and corresponding extension and capable of maintaining a uniform speed of grip separation as specified below. The tensile testing machine shall have a sufficient loading capacity in excess of 2000 N and a grip separation speed of (100 10) mm/min. The
29、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 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 g
30、rips more than 2 mm. The method of gripping shall not induce premature rupture close to the grips. The force measuring system shall meet at least Class 2 of EN ISO 7500-1 (i.e. 2 %). DIN EN 12317-2:2010-12 EN 12317-2:2010 (E) 6 6 Sampling Samples shall be taken in accordance with EN 13416. 7 Prepara
31、tion of test pieces and test specimens Test pieces to be used for jointing should be previously conditioned for at least 20 h at (23 2) C and at a relative humidity between 30 % and 70 %. Test pieces of the sheet are joined by the method(s) to be used for installation, both for side lap and end lap
32、jointing, with an overlap that is specified for the product. After jointing, the test piece shall be conditioned for a minimum of 2 h at (23 2) C and at (50 5) % RH before testing unless the manufacturer recommends differently. From each of these joint test pieces five rectangular test specimens (50
33、 1) mm wide shall be taken perpendicular to the joint. They shall have such a length, so that the ends of the initial distance between the two grips is (200 5) mm with the joint in the middle (see Figure 1).

34、 of joint DIN EN 12317-2:2010-12 EN 12317-2:2010 (E) 7 8 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. Each test s
35、pecimen shall be marked at the grips in order to identify any slippage out of the grips. The clear distance between the grips shall be between 3 and 4 times the width of the joint with a minimum of 120 mm and a maximum of 200 mm. No preload shall be applied. The test is carried out on a test specime
36、n at a temperature of (23 2) C and at a constant separating speed for the grips of (100 10) mm/min. The applied tensile force shall be recorded continuously until the test specimen ruptures or shears. The mode of failure shall be recorded. 9 Expression of results 9.1 Jointing information State all r
37、elevant information on the formation and the conditioning of the joint. 9.2 Evaluation The mode of failure of each of the specimens shall be reported (see Annex A). The shear resistance of the specimen is the maximum force recorded during the test. List the individual values for each set of five spe
38、cimens in Newton. Calculate and state the shear resistance of the joint as the mean value to the nearest Newton. Calculate and state the standard deviation. Disregard any test result where the test specimen breaks less than 10 mm from the grips or slips by more than the permitted limit within the gr
39、ips of the tensile testing machine, and retest with a replacement specimen. 9.3 Precision of the test method No information is available at this time. 10 Test report The test report shall include at least the following information: a) reference to this document (EN 12317-2) and any deviation from it
40、; b) all details necessary to identify the product tested; c) all details of how the weld was carried out; d) information on sampling in accordance with Clause 6; e) details of preparation of the test specimen in accordance with Clause 7; DIN EN 12317-2:2010-12 EN 12317-2:2010 (E) 8 f) test results
41、in accordance with Clause 9; g) the shear resistance and the failure mode; h) any peculiarities in the method employed or encountered during the test; i) date of the test(s).
