This European Standard shall be given the status
18、 of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2001, and conflicting national standards shall be withdrawn at the latest by March 2001. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follow
19、ing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This European Standard is inte
20、nded 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 installed in the works. This test is intended to be us
21、ed in conjunction with European Standard “Definitions and Characteristics“ for plastic and rubber sheets for roof waterproofing. 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
22、 roof waterproofing. NOTE The shearing characteristics of a joint between two widths 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 This European Standard incorporates, by dated or undat
23、ed references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when
24、incorporated in it by amendment or revision. For undated references, the latest editions of the publication referred to apply.

25、eets for waterproofing Bitumen, plastic and rubber sheets for roof waterproofing Rules for sampling 3 Definitions For the purpose of this standard, the following definition applies: 3.1 Shear resistance: The maximum tensile force required to extend a prepared joint test specimen, in shear, until it
26、breaks or separates. Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 09:53:10 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 4 EN 12317 - 2:2000 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
27、 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 a uniform speed of grip separation as specified below. The tensile testing machine shall have a sufficient loading c
28、apacity in excess of 2000 N 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 of the increase of the force applied to th
29、e test specimen. The test specimen shall be held so that it does not slip in the grips 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%). 6 Sampling Samples shall be taken
30、in accordance with prEN 13416:2000. 7 Preparation 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 f
31、or installation, both for side lap and end lap 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 jo
32、int test pieces five rectangular test specimens (50 ? 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). Licensed Copy: sheffieldun sheffieldu

34、at the longitudinal axis of the test specimen, the axis of the tensile testing machine and the grips are correctly aligned. Each test specimen shall be marked at the grips in order to identify any slippage out of the grips. The clear distance between the grips shall be (200 ? 5) mm. No preload shall
35、 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 tensile force shall be recorded continuously until the test specimen ruptures or shears. The mode of failure shall be recorded. Li

37、the specimen shall be reported. The shear resistance of the specimen is the maximum force recorded during the test. List the individual values for each set of five specimens in Newton. Calculate and state the shear resistance of the joint as the mean value to the nearest Newton. Calculate and state
38、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 grips of the tensile testing machine, and retest with a replacement specimen. 9.3 Precision of the test method No information is availa
39、ble at this time. 10 Test report The test report shall include the following information: a) a reference to this European Standard (EN 12317-2) 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 pr
40、eparation of the test specimen in accordance with clause 7; e) the test results in accordance with clause 9 ; f) any peculiarities in the method employed or encountered during the test; g) the date of the test(s).
