This European Standard shall be given the status of a national standard, eithe
18、r 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of an identical text or by endorsement, at the latest by March 2001, and conflicting national standards shall be withdrawn at the latest by March 2001.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 following countries are bound to imp
19、lement 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 intended for characterisation of p
20、lastic 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 used in conjunction with Europe
21、an 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 peeling of joints between two adjacent sheets of the same plastic or rubber sheets for roof waterproofing. This test
22、 method will be used mainly for testing the joints in mechanically fastened plastic or rubber sheets for roof waterproofing. NOTE The peeling 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 ove
23、rlap and the workmanship. 2 Normative references This European Standard incorporates, by dated or undated 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, subseq
24、uent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest editions of the publication referred to apply. EN ISO 7500-1Metallic materials Verification of static uniaxial testin

26、ance: The tensile force required to completely separate a prepared joint test specimen by peeling. Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 09:40:33 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 4 EN 12316 -2:2000 4 Principle The principle of the test is to pull a test specimen to pe
27、el 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 specified below
28、. 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 of t
29、he 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. 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
30、%). 6 Sampling Samples shall be taken in accordance with prEN 13416:2000.

31、 Page 5 EN 12316-2:2000 Dimensions in millimetres Key 1 Grip w Width of joint Figure 2 - Peel strength testing of side and end laps 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 h
32、umidity between 30 % and 70 %. Test pieces of the sheet are joined by the method(s) to be used for installation. 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 the
33、se joint test pieces, five rectangular test specimens (50 ? 1) mm wide shall be cut, perpendicular to the joint. They shall have such a length, that the ends of the specimen fill the grips and that the complete overlap can be tested perpendicular to joint (see Figure 1 and Figure 2). Rectangular joi
34、nt 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 Procedure The test specimen shall be firmly held in the grips of the tensile testing machine, taking care that the lon
35、gitudinal 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 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
36、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 joint shall be recorded. Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 09:40:33 GMT+00:00 2006, Uncontro

Disregard any test result where the test specimen breaks less than
38、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 shall be reported. 9.2.1 Maximum peel resistance From the graph read the maximum force and record as the maximum peel resistance
39、 of the test specimen in N/50 mm (relevant if the test specimen ruptures and no peel occurs and there is only one peak). 9.2.2 Average peel resistance (Relevant only if peel occurs) The first and last quarter of the graph shall not be included when calculating the average peel resistance of the test
40、 specimen. An average value is calculated on the remaining section by considering 10 equidistant values and expressed as N/50 mm (see Figure 3).
