16、le sheets for waterproofing, the Secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2000, and conflicting national standards shall be withdrawn at the lates
17、t by March 2000. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherla
18、nds, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This European Standard is intended for the characterization of bitumen sheets as manufactured or supplied before use. The test method relates exclusively to products, or to their components where appropriate, and
19、not to waterproofing membrane systems composed of such products and installed in the works. This test is intended to be used in conjunction with European Standards on product specifications for reinforced and unreinforced bitumen sheets for roofing. 1 Scope This European Standard specifies a test me
20、thod for determining the resistance to peeling of joints between two adjacent sheets of the same bitumen-based roofing sheets. This test method is intended to be used for testing the joints in mechanically fastened single layer bitumen roofing. The peeling characteristics of a joint between two widt
21、hs of bitumen-based sheets vary considerably depending on the material, on the method of jointing (flame or heat welding, hot adhesive or bitumen, cold adhesive, etc.) the size of the overlap and the workmanship. 2 Normative references This European Standard incorporates by dated or undated referenc
22、e, 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 incorporated
23、 in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 10002 - 2, Tensile testing of metallic materials - Part 2: Verification for the force measuring system of the tensile testirg machine. 3 Definitions For the purpose of this standard,
24、 the definitions indicated in 3.1 and the corresponding European Standard on product specifications appiy. 3.1 peel resistance the tensile force required to completely separate a prepared joint test specimen by peeling Q BSI 03-2000 Page 4 EN 12316-1:1999 4 Principle A test specimen of a joint is pu
25、lled at a constant speed until complete separation occurs. The tensile force is continuously recorded throughout the test. 5 Apparatus Tensile testing machine equipped with a continuous recording of force and corresponding distance, capable of maintaining uniform rate of grip separation as specified
26、 below. The tensile testing machine shall have a sufficient loading capacity (at least 2 O00 N) and a sufficient distance of grip separation, with a grip separation speed of (100 f IO) mmlmin. The width of grips shall be not less than 50 mm. The tensile testing machine shall be equipped with grips o
27、f a type which maintains or increases the gripping pressure as a function of the increase of the force applied to the test specimen. The test specimen should be held so that it does not slip n the grips more than 2 mm. To prevent slipping from the grips exceeding 2 mm it will be permitted to use coo
28、led grips The method of gripping shall not induce premature failure at or in the grips. The force measuring system shall meet at least class 2 in accordance with table 2 of EN 10002 - 2 (.e. i2 %). 6 Sampling and preparation of joint test pieces Samples shall be taken in accordance with the correspo
29、nding European Standard. Joint test pieces to be used for providing test specimens should be previously conditioned for at least 20 h at (23 f 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 with the unbonded ma
30、terial left on one side of the joint (see figure 1). Joint test pieces should be prepared representing all the ways of jointing. 7 Preparation test specimens From each of these joint test piece five rectangular test specimens (50 f 1) mm wide shall be cut, perpendicular to the joint. They shall have
31、 such a length that the ends of the specimen fill the clamps and that the complete overlap can be tested (see figure 1 and figure 2). Test specimens should be conditioned for at least 20 h before the test at (23 i 2) OC and at a relative humidity between 30 % and 70 %. When cold adhesives are used f
32、or jointing it may be necessary to increase the conditioning time according to the manufacturers information O BSI 03-2000 Page 5 EN 12316-1:1999 Dimensions in millimetres n w -width of joint Figure 1 Preparation of test specimen from specially made joint test pieces of side and end laps Dimmensions

34、 of the tensile testing machine and the grips are correctly aligned. The clear distance between the grips shall be (100 f 5) mm. No preload shall be applied. The test shall be camed out at (23 i 2) OC with a constant speed of grip separation of (100 i 1 O) mrnlmin. The applied force, in N, shall be
35、recorded continuously until the test specimen separates. The mode of failure of the joint shall be noted. 9 Expression of results, evaluation and precision of test method 9.1 Evaluation A force distance record shall be drawn up for each test specimen. 9.1.1 Maximum peel resistance Record the maximum
36、 force as the maximum peel resistance of the specimen expressed in N per 50 mm. 9.1.2 Average peel resistance The first and last quarter of the recorded data shall not be included when calculating the average peel resistance in N per 50 mm of the specimen. The average peel resistance value is calcul

38、2316-1:1999 NOTE: The purpose of the evaluation method specified here is to calculate an average peel resistance value which corresponds 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
39、the graphs do not feature any distinctive peaks. This can occur when testing some bonded materials. It should be noted that the resuts can vary, depending on the direction in which the specimens are taken. 9.2 Calculations From the resuts for each set of five test specimens both the mean value of ma
40、ximum peel resistance and average peel resistance shall be calculated and rounded to the nearest 5 N. 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 infomation: a) all details necessary to identify the pr
41、oduct tested; b) a reference to this European Standard (EN 1231 6-1 ) and any deviation from it; c) information of sampling in accordance with clause 6; d) details of preparation of the test specimens in accordance with clause 7 and a detailed description of the method of jointing; e) the test resul
42、ts in accordance with clause 9; f) the date of the test.
