19、land, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 12808-5:2009-01 EN 12808-5:2008 (E) 4 1 Scope This European Standard applies to all ceramic tile grouts for intern

20、al and external tile installations on walls and floors. This European Standard specifies the test method to be used to determine the water absorption coefficient due to capillary action when the grout surface contacts the water without any additional pressure. The coefficient is measured by means of

21、 prisms. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTE Ceramic tile grouts may also be used for other types of tiles (natural and agglomerated stones, etc.), where these do not adversely affect the stones. 2

For undated references, the latest edition of the referenced document (including any amendments) applies. EN 196-1:2005, Method of te

23、sting cement Part 1: Determination of strength EN 1067, Adhesives - Examination and preparation of samples for testing EN ISO 15605, Adhesives Sampling (ISO 15605:2000) 3 Sampling Take a sample of at least 2 kg of the product to be tested in accordance with EN ISO 15605 and EN 1067. 4 Test condition

24、s 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 Three gang mould with ground surfaces, made of steel, used for the preparatio

25、n of 40 mm x 40 mm x 160 mm prisms, in accordance with Clause 4.5 of EN 196-1:2005. 6.2 Jolting apparatus or jolting table used for the compaction of 40 mm x 40 mm x 160 mm grout specimen, in accordance with Clause 4.6 of EN 196-1:2005. 6.3 Tray with a flat base, large enough to contain three test s

26、pecimens. DIN EN 12808-5:2009-01 EN 12808-5:2008 (E) 5 7 Mixing of grouts The amount of water and/or liquid admix required for 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 t

27、ype 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 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

28、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 s. In the case of reaction resin grouts follow the manufacturers instructions. 8 Preparation of test specimens Insert a 1 mm th

29、ick, rigid, plastic (e.g. PTFE) or metal divider into each compartment of the mould, approximately in the middle, parallel to the ends. Mould the specimens immediately after the preparation of the grout, with the mould firmly clamped to the jolting table. Introduce, using a suitable scoop, the first

30、 of two layers of grout into each of the compartments, directly from the mixing bowl. Spread the layer uniformly, then compact using 60 jolts. Introduce the second layer of grout, level and compact with a further 60 jolts. Lift the mould gently from the jolting table, strike off excess of material a

31、nd smooth the surface with a flat trowel. Wipe off the grout left on the perimeter of the mould. Cover the mould with a glass plate according to EN 196-1. Place the mould, suitably identified, on a horizontal base in standard conditions, (23 2) C and (50 5) % R.H. After 24 h carefully remove the spe

32、cimen from the mould. Keep the demoulded prisms for 27 days in standard conditions leaving a clearance of at least 25 mm on all sides. Prepare six specimens for each grout. DIN EN 12808-5:2009-01 EN 12808-5:2008 (E) 6 9 Conditioning The test units are conditioned for 27 days in standard conditions,

33、(23 2) C and (50 5) % R.H. 10 Test procedure After 21 days from manufacture seal the side faces by means of a neutral curing silicone sealant so as to be water impermeable. After 28 days from manufacture, weigh, with 0,1 g precision, each test sample and then place them in the tray, with the upper s

34、urface down, immersed in water, 5 mm to 10 mm deep, taking care to prevent the prism faces from coming in contact with each other. Maintain the water level constant by adding water when necessary. After 30 min remove the test samples from water, quickly dry them by blotting with a dampened cloth and

35、 immediately weigh. Replace in the tray and repeat the procedure after 210 min. 11 Evaluation and expression of results Calculate the water absorption, in grams, after 30 min and 240 min of each sample using the following formula: dtmm =mtW where: Wmt is the water absorption, in grams; md is the mas

36、s of the dry specimen, in grams; mtis the mass of the specimen after immersion, in grams. Calculate the mean of at least three test samples. 12 Test report The test report shall provide the following information: a) number, title and issue of this European Standard; b) place and date of sampling; c)

37、 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 water or liquid used for preparing the grout; i) test results (water absorption, individual and mean values after 30 min and 240 min); j) any other factor that could have influenced the result.
