18、uminous sheets for roofing. It can also be used in other areas where it is relevant. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For u
19、ndated references, the latest edition of the referenced document (including any amendments) applies. EN 13416:2001, Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roof waterproofing - Rules for sampling ISO 3310-1, Test sieves Technical requirements and testing Part 1: Te
20、st sieves of metal wire cloth 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 surface upper side of the sheet, as used in situ; which is usually the inside of the roll 3.2 granule particle which does not pass a sieve as defined in B.1.2 4 Pri
21、nciple The method determines the adhesion of granules during a brushing test under specified conditions. The mass of brushed-off granules is compared to the original mass of granules on a test specimen cut off from the same roll. 5 Apparatus 5.1 Brushing machine, working automatically to perform out
22、ward and return cyclic linear movements between a replaceable brush applied with a force of (21,5 0,5) N on the surface of the test specimen, and the test specimen itself. The constant amplitude A of the relative movement of the axis of the replaceable brush is (200 20) mm, and the average displacem
23、ent speed is such that 50 cycles are achieved within (55 5) s. The brushing machine shall include suitable clamps, at least 50 mm wide, to restrain the ends of the specimen. 5.2 Replaceable brush, consisting of a block of a suitable material in which 22 holes are drilled as indicated in Figure A.1,
24、with a 4 mm diameter. From each hole, 22 polyamide 66 yarns, diameter 0,80 mm project (16 2) mm. The effective area of the replaceable brush, when loaded, is 80 mm 25 mm. The effective brushed area B, as shown in Figure A.2, is (A + 80) 25 mm2. A single replaceable brush shall be used for a maximum
25、of 100 tests of fewer if yarns are projecting less than 13 mm from a hole. 5.3 Balance, accurate to the nearest 0,01 g. BS EN 12039:2016EN 12039:2016 (E) 5 5.4 Machine, to cut or die-cut test specimens with a width of (50 1) mm in the desired length. 5.5 Room for conditioning, temperature (23 2) C a
26、nd (50 20) % relative humidity. 5.6 Household vacuum cleaner, 500 W, sucking air through an accessory 50 mm wide. 6 Preparation of test samples and test specimens 6.1 Sampling Sampling in accordance with EN 13416:2001. 6.2 Sampling and preparation of test specimens Test specimens shall be cut or die
27、-cut in the dimension (50 1) mm wide, length minimum 285 mm, from the samples in the length direction of the sheet. Condition five test specimens for (24 0,5) h in the climate room at (23 2) C. Suck the loose granules from the test specimens carefully moving the vacuum cleaner accessory over their s
28、urfaces. Determine the mass M1iof each test specimen to the nearest 0,01 g. 7 Procedure The mass of brushed-off granules is compared to the initial mass of granules of the test specimens cut from the same roll and in the same position on the sheet with respect either to its axis or right side or lef
29、t side. Determine the initial mass of granules in accordance with Annex B. Secure the test specimen onto the brushing machine using the clamps, and place the loaded replaceable brush on the test specimen, the length of the replaceable brush being in the length direction of the specimen (see Figure A
30、.2). Perform 50 cycles and remove the test specimen from the brushing machine. Repeat the procedure for each test specimen. Suck the loose granules from the test specimens moving the vacuum cleaner accessory over their surfaces. Determine the mass M2iof each test specimen to within 0,01 g. 8 Express
31、ion of results Determine the adhesion of granules (Mi), expressed as percentage of relative difference between the two masses of each test specimen using Formula (1): 100o2i1ii=GBMMM (1) where Gois the initial mass of granules per 1 m2in the same third of the sample where the specimens were cut in a
32、ccordance with EN 13416:2001, in gram/square metre (g/m2), as determined in Annex B; M1iis the mass of the test specimen before brushing, in gram (g); M2iis the mass of the test specimen after brushing, in gram (g); BS EN 12039:2016EN 12039:2016 (E) 6 B is the area effectively brushed, in square met
33、re (m2). 9 Accuracy The precision of the method is not specified. NOTE No report on interlaboratory tests on repeatability, r, or on reproducibility, R, is available. The accuracy will be specified when sufficient interlaboratory data are available. 10 Test report The test report shall include at le
34、ast the following information: a) all details necessary to identify the product tested; b) a reference to this European Standard and any deviation from it; c) information on sampling and details on preparation of test specimens in accordance with Clause 6; d) information on the test procedure in acc
35、ordance with Clause 7; e) the test results in accordance with Clause 8; f) date of the test.

37、eve in accordance with ISO 3310-1. B.1.3 Solvent, e.g. toluene, trichloroethylene or dichloromethane, according to national safety regulations. B.1.4 Balance see 5.3. B.2 Specimens Cut the specimens from the roll(s) which was (were) sampled in preparation for the granule adhesion test. Exclude the f
38、irst and the last metre in the length direction of the roll, and 100 mm nearest to the edge in the width direction of the roll. Divide the roll equally into three parts in the length direction. From each third, cut two specimens of (100 1) mm (100 1) mm to the nearest 1 mm (total area of each specim
39、en 0,01 m2) or alternatively 70 mm 50 mm (total area of each specimen 0,0035 m2). Each pair of specimens will be representative of the initial mass of granules found in the thirds of roll used for the adhesion test. B.3 Procedure B.3.1 The area Siof the specimen shall be calculated in m2. B.3.2 The
40、specimen shall be placed in the extractor with the solvent adjusted as necessary. B.3.3 Soluble components shall be separated by hot extraction, until the solvent in the hot extraction apparatus becomes colourless (usually 1 h to 2 h). B.3.4 The specimen shall be taken out of the extractor, dried at
41、 (105 2) C for at least 2 h. B.3.5 The granules shall be separated from other components using sieve (B.1.2). B.3.6 The mass of the granules Nishall be determined to the nearest 0,01 g. The procedure shall be repeated on each specimen. B.4 Calculation and expression of results B.4.1 Calculate the ma
42、ss per unit area of granules (Gi), expressed in g/m2, of each specimen using Formula (B.1): iiiSNG = (B.1) BS EN 12039:2016EN 12039:2016 (E) 9 where Niis the mass of the granules relative to one specimen, in gram (g); Siis the area of the specimen, in square metre (m2).
