Attention is drawn to

15、 the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.

16、ional Test Method C has been introduced in order to comply with extended experience gained in the use of plastic roofing sheets. Additionally a sample size reduction for Method B was introduced as well as an update specification of the soft support polystyrene (EPS) boards. This European Standard is

17、 intended for characterisation and classification of bitumen, plastic and rubber sheets as manufactured or supplied before use. This test method relates exclusively to products or to their components where appropriate, and not to waterproofing membrane systems composed of such products and installed

18、 in the works. This test is intended to be used in conjunction with product standards for bitumen, plastic and rubber sheets for roof waterproofing. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European

20、a, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 12730:2015EN 12730:2015 (E) 4 1 Scope This European Standard specifies a test for puncture by static loading for roofing membranes. Mechanical stress on membranes varies from static long-term loads to dynamic short-term loads. This

21、method represents the static category of load where the stress is applied over a period of time. This European Standard may also be applied for waterproofing. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for it

22、s application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13163, Thermal insulation products for buildings - Factory made expanded polystyrene (EPS) products - Specification EN 134

23、16, Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roof waterproofing - Rules for sampling 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 surface upper side of the sheet, as used in situ Note 1 to entry The surfac

24、e is usually the inside of the roll. 4 Principle The principle of the test is to apply a concentrated load over a period of time, through a puncturing tool onto the surface of the membrane, when lying on a specified soft support (method A or method C) or hard support (method B). The choice of the ap

25、propriate test method for the different kind of membranes and the fields of applications shall be defined in the relevant product standards. For the determination of resistance to static loading on soft support Method A is typically used for sheets that do not require protective measures when mechan

26、ical loads such as ladders, scaffoldings or other mounts are applied on them. Method C is intended for sheets which require the use of a protection layer in such construction situations. 5 Apparatus 5.1 General The testing apparatus consists of parts indicated in 5.2 to 5.6 (see Figure 1). 5.2 Guide

27、 rail The guide rail holds the loading rod in a vertical position. The vertical movement of the puncturing tool from the surface of the test specimen can be limited to (10 2) mm by the guide rail. BS EN 12730:2015EN 12730:2015 (E) 5 5.3 Loading rod The loading rod has the puncturing tool at the lowe

28、r end and a support for the loading discs in the middle. The loading rod and puncturing tool are calibrated with the support disc to have a mass of 2 kg. 5.4 Loading discs A complete set of loading discs contains one disc with a mass of 3 kg and three discs with a mass of 5 kg. 5.5 Puncturing tool T

29、he puncturing tool is in the shape of a 10 mm diameter ball with a 5 mm diameter thread for attachment to the loading rod. The puncturing tool is made to the following specification: a) formed in steel material b) hardened to 50 HRC c) ball diameter (10 0,05) mm d) surface, unmarked and polished. 5.

30、6 Supports and test frame 5.6.1 General Two types of supports in accordance with 5.6.2 or 5.6.3 can be used. 5.6.2 Soft support to be used with Method A and Method C The test specimen is fixed in a clamping frame and laid directly in contact with the support. The inside dimensions of the frame are 3

31、00 mm 300 mm. The clamping frame shall not allow movement exceeding 1 mm of the sample during the test. If necessary the clamping frame (No. 6 in Figure 1) may contain spikes or nails to minimize the movement of the sample to less than 1 mm during the test. The support is expanded polystyrene (EPS-Q

32、uality CS(10)150, see EN 13163) with sizes 300 mm 300 mm 50 mm. The support shall be centred below the sample (Figure 1). 5.6.3 Hard support to be used with Method B The test specimen is loose laid directly onto a concrete paving slab with sizes 300 mm 300 mm 40 mm. The surface of the concrete shall

33、 be even and without defects. The support shall be centred below the sample (Figure 1).

36、3 Gasket 6 Support Figure 2 Example of a vacuum device 6 Sampling Test samples shall be taken in accordance with EN 13416. 7 Preparation of test specimens The test specimens with dimensions (550 mm 550 mm) 2 mm for method A and method C and (300 mm 300 mm) 2 mm for method B are taken right across th

37、e width of the roll excluding 100 mm from the edges. The number of test specimens shall be 3 per loading stage for each method. The test specimens are conditioned at least 24 h at the specified test conditions. 8 Procedure 8.1 General Testing is carried out at a temperature of (23 2) C. For every te

38、st at each loading interval a new test specimen shall be used, and a new polystyrene panel for the soft support test (see also 8.2). The test specimen is laid on the horizontal support with the surface upwards. BS EN 12730:2015EN 12730:2015 (E) 8 The puncturing tool is positioned at the centre of th

39、e test specimen. The testing is carried out with three parallel test specimens in intervals of loading starting with 5 kg. The load is then increased by steps of 5 kg until perforation occurs, or up to a maximum load of 20 kg. The duration of loading shall be 24 h for each loading interval. The load

40、 is applied carefully, without shock. After each loading interval the test specimens are examined for a possible puncture by coating the surface where the load has been applied with a soap solution between (7 2) min after the test. A pressure difference of 15 kPa (0,15 bar) is applied to the area wh

41、ere the load has been applied by means of a vacuum or pressure device with the lower pressure at the surface of the sheet. If after 60 s no air bubbles are visible, the test specimen is considered not punctured. The material under testing is considered to resist the given load when three out of thre

42、e test specimens are not punctured. 8.2 Method A When testing on soft support the test specimen is fixed in the clamping frame. The downward movement of the ball from the surface of the test specimen should be limited to 40 mm as shown in Figure 1. 8.3 Method B When testing on hard support the test

43、specimen is loose laid on the concrete paving slab. 8.4 Method C When testing on soft support the test specimen is fixed in the clamping frame. The downward movement of the ball from the surface of the test specimen shall be limited to 10 mm as shown in Figure 1. 9 Expression of test results The res

44、istance to static loading is expressed as the load which has not caused leakage of the flexible sheet for roofing or waterproofing in three out of three parallel test specimens according to the method applied (method A, method B or method C). 10 Test report The test report shall include the followin

45、g information: a) all details necessary to identify the product tested; b) a reference to this European Standard (EN 12730) and any deviation from it; c) information on sampling in accordance with Clause 6; d) details of preparation of the test specimen in accordance with Clause 7; e) information on

46、 the test procedure, indicating the method used (A,B or C) (Clause 8); f) the test results in accordance with Clause 9; g) the date of the test.
