EN 15057:2006 (E) 4 Introduction Different fibre-cement profiled sheets on the market incorporate additional features to contribute to security during construc
18、tion of the roof. Fibre-cement profiled sheets have been evaluated for impact resistance by a number of national methods, designed to simulate the impact of accidental falling on the roof. The results from the different existing methods are not directly comparable. This European Standard establishes
19、 an agreed method for evaluation of impact resistance of fibre-cement profiled sheet products, based on the experiences obtained over the last number of years in different countries. This is a product standard with no classifications, but this test procedure with different drop heights or number of
20、drops may be used by national regulators to set classifications for roof assemblies. The performance of a roof constructed with these products depends not only on the property of the product as required by this European Standard, but also on the design, construction and performance of the roof as a
21、whole in relation to the environment and conditions of use. EN 15057:2006 (E) 5 1 Scope This European Standard specifies a soft body impact test method for fibre-cement profiled sheets for roofing. This European Standard applies to fibre-cement profiled sheets conforming to EN 494 and of length grea
22、ter than or equal to 1,04 m. It applies only to products as delivered. NOTE This European Standard can be applied, after agreement between manufacturer and purchaser, to curved sheets. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、sembly for a period of at least 60 s. compliance is required by 8 out of 8 sheets. If 1 of the 8 sheets fails, a further 8 sheets shall be tested with a compliance requirement of 8 out of 8 sheets passing the test. 6 Sampling procedure 6.1 Sampling method Take an adequate number of full size sheets
31、(16 or 24) drawn at random from a consignment of at least 151 sheets or, in case of continuous production, from a production batch. All sheets used on the test assembly shall be from the same consignment or production batch. The size of the production batch is chosen by the manufacturer up to a maxi
32、mum of one weeks production. If 1 sample out of 8 fails in the first test, the samples for retest are taken in the same manner. 6.2 Type testing The impact resistance test is a type test and shall be performed to demonstrate conformity to this European Standard. For continuous production the type te
33、st shall be repeated at least once every year. EN 15057:2006 (E) 7 7 Test method for the determination of soft body impact resistance 7.1 Principle The soft body impact resistance is determined by dropping a 50kg spheroconical bag with no initial speed from a height of 1200mm perpendiculary into the
34、 centre of the mid sheet of a given test assembly (see Figure 2) and measuring the time for which the bag is retained by the same sheet. NOTE This creates an impact energy which is in excess of the impact energy released by a person falling from a standing position. 7.2 Test apparatus The apparatus
35、consists of: a) A frame (see Figure 2) of minimum height 600 mm, made of IPN or IPE 140 bars reinforced by U braces of height 50 mm. These shall be either welded or screwed. Minimum length of the frame: 3 000 mm. Width of the frame: 1 300 mm, measured at the inside of the IPN or IPE 140. This frame
36、shall be placed on a flat, solid surface. b) Supports (see Figure 3) made of 4 IPN or IPE 100 bars of minimum length 1 430 mm. Two steel plates of 200 mm x 60 mm x 10 mm are welded on at each end. The supports are either welded or screwed into position parallel to each other using bolts M 10 x 30. T
37、he upper face of the supports shall be in a horizontal plane with a tolerance of 1 mm. c) A spheroconical canvas or leather bag of diameter (400 40) mm (see Figure 1 and ISO 7892) filled with (3,0 0,3) mm diameter glass spheres to give a total weight of (50 0,5) kg as the soft body impactor. d) A sy
38、stem for the instant release of the bag without application of initial energy. e) Hooks of the dimensions described in Figure 4 with a characteristic resistance of 2300 N. The hooks will be fitted with a washer as described in Figure 7. f) A measuring rod of (1 200 2) mm to measure the distance h be
39、tween the base of the bag and the crown of the corrugation of the sheets to be tested. g) A torque spanner for adjusting the fittings.

42、re 7 Washer 7.3 Number of tests The test shall be carried out on the test assembly described in 7.5 and shall consist of 1 impact per sheet length. 8 tests are required with a new assembly for each of the tests. The length of the overlap and underlap sheets shall be (760 10) mm. The point of impact
43、shall be in the centre at mid span (see Figure 2). The relevant sheet length span and overlap are given in Table 1. EN 15057:2006 (E) 15 Table 1 Sheet length, overlap and span Sheet length (mm) Overlap (mm) nominal value Span (mm) 1 040 140 900 1 220 140 1 080 1 520 140 1 380 The specimens should be
44、 tested with one of the above values, or at the maximum allowed by code of practice or recommended by the manufacturer. The tolerance for each of the dimensions in Table 1 is 10 mm for the sheet length and 2 mm for the span. 7.4 Moisture content of the test specimens The specimens to be tested shall
45、 have an average moisture content in the range of 8 % to 16 %. 7.5 Test assembly Fix the IPN/IPE 100 bars (see Figure 3) on the frame according to the relevant span (see Table 1). The sheets are drilled to a diameter of 9 mm at positions A and B (see Figure 5) according to both the length and number
46、 of corrugations, as specified in Tables 2 and 3.

The sheets shall have two fixings at each end, at the top of the c
48、orrugations as specified in Tables 2 and 3. The sheets shall be fixed symmetrically with respect to the longitudinal axis of the frame and with the crowns of the corrugations perpendicular to the IPN bars (see Figures 5 and 6). Fix the sheets to the IPN bars at each location using hooks and washers
49、as defined in 7.2. The overlap and underlap sheets are fixed in the same way. The screws of the hooks are then tightened with the torque spanner applying a moment of 1,5 Nm. The vertical axis of the bag is positioned at the centre of the sheet at midspan (see Figure 2). The bag is raised and reformed in the spheroconical shape defined by ISO 7892 so that its base hangs at 1 200 mm from the crown of the corrugation. Check the drop height using the measuring rod. The bag is released
