This European S
15、tandard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2000, and conflicting national standards shall be withdrawn at the latest by September 2001. According to the CENKENELEC Internal Regulations, the nationa
16、l 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, Nethetlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Intr
17、oduction This European Standard is intended for the characterization and/or classification of bitumen sheets as manufactured or supplied before use. The test method relates exclusively to products, or to their components where appropriate, and not to waterproofing membrane systems composed of such p
18、roducts and installed in the works. This test is intended to be used in conjunction with European Standards on product specification for reinforced and unreinforced bitumen sheets for roofing. This test is intended to determine the dimensional changes in bitumen sheets as a result of production-indu
19、ced internal stresses released under the effect of heat. Excessive dimensional changes can result in detrimental stresses in service. This test can be used to measure basic properties of the bitumen sheeting directly relevant to its fitness for purpose for waterproofing applications. 1 Scope This Eu
20、ropean Standard specifies the determination of the dimensional stability of bitumen sheets. 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
21、 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 in it by amendment or revision.

35、6 Sampling Test samples shall be taken in accordance with the corresponding European Standard. Five rectangular test specimens with dimensions of (250 f 1) mm x (50 f 1) mm are taken from the test sample uniformly over the width of the sheet and with the larger dimension in the longitudinal directio
36、n of the sheet. The test specimens shall not be taken within 150 mm of the edges of the sheet. In the case of sheets with more than one reinforcement 10 test specimens shall be taken. The test specimens shall be numbered consecutively, beginning from one edge of the sheet and the upper and lower fac
37、es of the sheet shall be marked. 7 Preparation of test specimens Any protective film shall be removed, preferably by applying a strip of adhesive tape to it at ambient temperature, cooling the test specimen to approximately the presumed cold bending temperature and then pulling the adhesive tape fro
38、m the test specimen. Alternatively, or additionally, the film can be removed by means of a compressed air jet (maximum pressure approximately 5 bar, nozzle diameter approximately 0,5 mm). If it is not possible to remove the film using these methods, a gas flame may be used but for the least time nec
39、essary to destroy the film but not otherwise to damage the test specimen. The coating on the lower face of the test specimen shall be removed down to the reinforcement as shown in Figure 1 or Figure 2 using the metal template and a heated spatula or similar device. The reinforcement shall not be dam
40、aged. The measuring bases as shown in Figure 1 and Figure 2 are bonded to the exposed reinforcement with a solvent-free adhesive. In the case of test specimens for the optical measuring method, the aluminium tag is fastened as shown in Figure 1 by means of two staples at right angles to the longitud
41、inal edge of the test specimen through the reinforcement in such a way that the imaginary line through the staples is approximately 200 mm from the middle of the measuring base. In the case of sheets without reinforcement, the measuring bases are bonded directly to the surface of the test specimen.
42、In the case of sheets with more than one reinforcement, both sides shall be tested. The test specimens prepared in this way are then conditioned on a flat talced base for at least 24 h at (23 f 2) “C. The compass and steel plate and, where appropriate, the calliper measuring device are also conditio
43、ned at the same temperature. 8 Procedure 8.1 Method A (optical method) When using the optical method (see 5.3) the reference measuring length Lo on the test specimen (see Figure 1) is determined at (23 i 2) “C to the nearest I mm using the length measuring device. Then the first measuring mark is ap
44、plied to the test specimens. For this, the steel plate with the cut outs is placed over the measuring base and the aluminium tag. The centering cone of the compass is then positioned on the measuring base and a measuring mark in the form of a curved line is scribed into the aluminium tag with the pi
45、n. This is done without any additional pressure, just the dead weight of the compass. The first measuring mark shall be identified approgriats. QBSI 02-2000 Page 8 EN 1107-111999 8.2 Method B (calliper method) Using the test specimens to be tested in accordance with the calliper method (see 5.4), th
46、e measuring device is placed on the measuring bases at a temperature of (23f2)“C and the distance between the measuring bases is measured accurately to the nearest 0,05 mm and noted as the reference measuring length Lo. 8.3 The oven is preheated to a temperature of (80 f 2) OC. The temperature is co
47、ntrolled by the thermocouple positioned in the proximity of the test specimens in the test area. Then, the test specimens with the measuring base uppermost are placed in the oven for 24 h f 10 min at (80 f 2) “C supported on a talcumed glass plate. The glass plate shall be coated with sufficient tal
48、cum to prevent the test specimens sticking to it. The temperature shall be maintained throughout the whole conditioning period in the charged part of the oven. After the conditioning period, the glass plates with the test specimens are removed from the oven and allowed to cool for at least 4 h at (2
49、3 f 2) OC. General (methods A and B) 9 9.1 Method A (optical method) The test specimens are then given a second measuring mark as described in 8.1. The distance between the outside contours of the two marks is measured in the radial direction (see Figure 1) to the nearest 0,05 mm with a precision length measuring device on each test specimen. The individual measured values are given as a percentage of Lo. Recording of results, evaluation and precision of test method 9.2 Method B (calliper method) The distance between the measuring bases on the test specimen is measured a
