This European Standard shall be given th
16、e status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2000, and conflicting national standards shall be withdrawn at the latest by September 2000. According to the CENEENELEC Internal Regulations, the national standards organization
17、s of the following 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 standard h
18、as been prepared by the Technical Committee CENTTC 254 to determine the watertightness of sheets for waterproofing. This standard has been prepared for applications in roofing but it may also be used in other areas where it is relevant. This standard is intended for characterization of flexible shee
19、ts for waterproofing as manufactured or supplied before use. This standard relates exclusively to products and not to waterproofing membrane systems composed of such products and installed in the works. 1 Scope This European Standard applies to bitumen, plastic and rubber sheets for roof waterproofi
20、ng and specifies procedures for determining the watertightness, .e. the resistance to ponding water or to hydraulc pressure absorbed by a limited part of the surface, of factory made products. This standard may also be used in other waterproofing areas. 2 Normative references This European Standard
21、incorporates by dated or undated reference, 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 these publications apply to this draft
22、European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. prEN 13416:1999 Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roof waterproofing - Rules for sampling. 3 Definitions
23、 For the purpose of this standard, the following definitions apply. 3.1 upper side: the upperside of the sheets, as laid, usually the inside of the roll 3.2 watertightness: condition of flexible sheet for waterproofing if: a) b) in case of method A: no discoloration is observed of the filter paper a
24、bove the surface of a test specimen at the applied water pressure during the total test period in case of method B: the applied maximum pressure does not drop by more than 5 % of the initial value Q BSI 09-2000 Page 4 EN 1928:2000 4 Principle Due to the nature of the bitumen, plastic or rubber sheet
25、s concerned, the test procedure given in this standard consists of two methods. 4.1 Method A Test procedure for sheets intended for use in low pressure application, e.g. roofing, underlay, vapour control layer. The specimen is subjected to a pressure up to 60 kPa for 24 h. 4.2 Method B Test procedur
26、e for sheets intended for use in high pressure application, e.g. special roofs, tunnelling and tanking. Submission of a test specimen to a specified water pressure for 24 h against a disk containing four slots of specified form and dimensions. The test specimen is observed to establish whether it re
27、mains watertight. 5 Apparatus 5.1 MethodA A cylindrical metal flanged box, with a 150 mm diameter aperture, is connected to an open ended pipe or vessel which rises to a height of not less than 1 m, generally as shown in Figure 1.

34、 Preparation The specimens shall be taken evenly distributed across the width of the sheet, the outer ones 100 mm of the edges. The longitudinal direction on the test specimens shall be marked parallel to direction of production. The number of test specimens shall be as specified in the relevant pro
35、duct standard, but shall be a minimum of three. 7.2 Dimensions of the test specimens 7.2.1 MethodA Circular test specimens with a diameter of (200 f 2) mm. 7.2.2 Method B Circular test specimens wih a diameter equal to the external diameter of the slotted plate (approximately 130 mm). 7.3 Conditioni
36、ng of test specimens The test specimens shall be stored for at least 6 h at (23 f 5) “C prior to testing. 8 Procedure 8.1 Test conditions The test shall be camed out at (23 f 5) “C. In case of dispute it shall be camed out at (23 f 2) “C and (50 f 5) % relative humidity (RH). The test pressure shall
37、 be specified in the product specification. It shall be ensured that the margins are watertight. 8.2 Procedure method A Insert the test specimen into the apparatus (5.1). Tighten the wing nuts (9) firmly onto the clamping ring. Open the valve (1 1) to let water in while valve (IO) is left open to al
38、low air to escape. Close valve (IO) once water passes through indicating that the apparatus is filled. Apply the required pressure to the upper side of the test specimen. Maintain the pressure for a period of (24 f 1) h. . Inspect the test specimen to see if there has been discoloration of the upper
39、 filter paper. 8.3 Procedure method B Fill the apparatus in accordance with Figure 2 with water until overflowing. Purge the water line thoroughly. Place the test specimen with its upper side downwards in the apparatus and cover with the specified slotted plate, one of the slots (see Figure 4) being
40、 parallel to the longitudinal direction of the sheet. Place the cover and progressively tighten until the specimen is tightly in place. Dry the non-exposed side of the specimen with a cloth or with compressed air. Pressurize progressively to the specified test pressure. Once the test pressure is rea
41、ched, maintain the pressure for a period of (24 f I) h. Observe the watertightness of the test specimen after the testing time (sudden pressure drop or presence of water on the non-exposed face of the test specimen).

42、ion of results 9.1.1 Method A Any specimen with evidence of water penetration through to the upper filter paper is deemed to have failed the test. The sheet is deemed to be watertight when all specimens pass the test. 9.1.2 Method B The watertightness test is considered passed if all test specimens
43、remain watertight after the specified testing time. 9.2 Precision Precision is not specified by this standard. NOTE No report on inter-laboratory tests of repeatability and reproducibility is available. 10 Test report The test report shall include at least the following information: a) all details n
44、ecessary to identify the product tested: b) a reference to this European Standard (EN 1928) and any deviation from it; c) information on sampling in accordance with clause 6; d) details of preparation of test specimens in accordance with clause 7; e) test procedure indicating method A or B used, inc
45、luding the test pressure and any deviation: 9 the test results in accordance with clause 9: g) the dates of the tests.
