24、 ISO 15605 and EN 1067. 4 Test conditions Standard conditions shall be (23 2) C and (50 5) % R.H. and a speed of air in the working area less than 0,2 m/s. 5 Test materials Condition all test materials for at least 24 h under standard conditions. 6 Apparatus 6.1 Abrasion apparatus consisting essenti

25、ally of a rotating disk, a storage hopper, a test specimen support and a counterweight in accordance with EN ISO 10545-6 (see Figure 1). 6.2 Abrasive material white fused aluminium oxide of grain size 80 (see EN ISO 10545-6).

26、f measuring to 0,1 mm (see EN ISO 10545-6). 6.4 Template: a smooth, square, rigid, non absorbent frame (e.g. in polyethylene or PTFE), with internal dimensions of (100 1) mm x (100 1) mm and thickness of (10 1) mm. 7 Procedure 7.1 Mixing of grouts The amount of water and/or liquid admix required for

27、 preparing the cementitious grout shall be as stated by the manufacturer in parts by weight, i.e. liquid to dry powder. Prepare at least 2 kg of the grout in a mixer of the type described in Clause 4.4 of EN 196-1:2005, using the slow speed settings, (140 5) r/min rotation and (62 5) r/min planetary

28、 movement. Carry out the following procedure: pour the liquid into the pan; scatter the dry powder over the liquid; mix for 30 s; take out the mixing paddle; scrape down the paddle and pan within 1 min; replace the paddle and mix for 1 min. Let the grout mature as specified in the manufacturers inst

29、ructions, and then mix for a further 15 s. In the case of reaction resin grouts follow the manufacturers instructions. 7.2 Preparation of test specimens Place the template over a polyethylene film. Trowel a sufficient quantity of grout across the template and then screed clean so as to fill neatly a

30、nd completely the hole in the template. Cover with a glass plate according to EN 196-1. After 24 h remove the template carefully. Condition the units according to the test requirements. Prepare two specimens for each grout sample. 7.3 Conditioning The test units are conditioned for 27 days in standa

31、rd conditions: (23 2) C and (50 5) % R.H. 7.4 Test procedure Place a test specimen in the apparatus, with the trowelled face against the wheel, so that it is tangential against the rotating disc. Ensure that the feed of abrasive material into the grinding zone is uniform at a rate of (200 10) g per

32、100 revolutions. DIN EN 12808-2:2009-01 EN 12808-2:2008 (E) 6 Rotate the steel disc for 50 revolutions. Remove the test sample from the apparatus and measure the chord length of the groove by means of the measuring gauge to the nearest 0,5 mm. Test each sample in at least two places on its trowelled

33、 surface. 8 Expression of results The resistance to abrasion is expressed as the volume V of material removed, in cubic millimetres. This is calculated from the chord length of the groove by means of the expression: 8sin1802dhV= where sin ( / 2) = L / d; d is the diameter of the rotating disc (in mm

34、); h is the thickness of the rotating disc (in mm); is the angle (in degrees) subtended at the centre of the rotating disc by the chord (see Figure 2); L is the length of the chord (in mm). Some equivalent values are given in Table 1. 9 Test report The test report shall provide the following informa

35、tion: a) number, title and issue of this European Standard; b) place and date of sampling; c) type of grout, commercial designation and manufacturer name; d) identification of the test sample; e) handling and storage of samples before testing; f) test conditions; g) date of testing; h) amount of wat

36、er or liquid used for preparing the grout; i) test results (volume V for each individual groove and the mean value, in cubic millimetres); j) any other factor that could have influenced the result.
