16、pared by Technical Committee CEN /TC 67 “Ceramic tiles“, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2002, and conflicting national standards shal
17、l be withdrawn at the latest by June 2002. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland,

19、 for internal and external tile installations on walls and floors. This standard specifies the test method to be used to determine the abrasion resistance of ceramic tile grouts. This European Standard does not contain performance requirements or recommendations for the design and installation of ce
20、ramic tiles. NOTECeramic tile grouts can also be used for other types of tiles (natural and agglomerated stones, etc.), where these do not adversely affect the stones. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These
21、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, any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undate
22、d references the latest edition of the publication referred to applies (including amendments). EN 1066, Adhesives Sampling. EN 1067, Adhesives - Examination and preparation of samples for testing.

23、etermination of resistance to deep abrasion for unglazed tiles (ISO 10545- 6:1995). 3 Sampling Take a sample of at least 2 kg of the product to be tested in accordance with EN 1066 and EN 1067. 4 Test conditions Standard conditions shall be (23 2) C and (50 5) % R.H. and a circulation of air in the
24、working area less than 0,2 m/s. 5 Test materials Condition all test materials for at least 24 hours under standard conditions. 6 Apparatus 6.1Abrasion apparatus consisting essentially of a rotating disk, a storage hopper, a test specimen support and a counterweight in accordance with EN ISO 10545-6
25、(see Figure 1). 6.2Abrasive material white fused aluminium oxide of grain size 80 (see EN ISO 10545-6). 6.3Measuring gauge capable of measuring to 0,1 mm (see EN ISO 10545-6). 6.4Template a smooth, square, rigid, non-absorbent frame (e.g. in polyethylene or PTFE), with internal dimensions of (100 1)
26、 mm x (100 1) mm and thickness of (10 1) mm.

27、e 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 4.4 of EN 196-1:1994, using the slow speed settings, (140 5) rpm rotation and (62 5) rpm planetary movement. Carry out the following procedure: ? pour
28、 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 if and as specified in the manufacturers instructions, and then mix for a further 15
29、 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 sufficient quantity of grout across the template and then screed clean so as to fill neatly and completely the hole in the template. C
30、over with a glass plate according to EN 196-1:1994. After 24 hours remove carefully the template. 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 standard conditions (23 C 2 C and 50 %
31、 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 (100 10) g per 100 revolutions. Rotate the ste
32、el 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 surface. 8 Expression of results The resistance to abrasion is expressed as
33、 the volume V of material removed, in cubic millimetres. This is calculated from the chord length of the groove by means of the expression: ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 8 sin 180 2 hd V? ?

Some equivalent
35、values are given in Table 1. 9 Test report The test report shall provide the following information: a) number, title and issue of this European Standard; b) the place and date of sampling; c) type of grout, commercial designation and manufacturer name; d) identification of the test sample; e) handli
36、ng and storage of samples before testing; f) test conditions; g) date of testing; h) amount of water 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.
