This standard applies to reaction resin ceramic ti
23、le grouts and adhesives for internal and external ceramic tile installations on walls and floors. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles and grouts. NOTECeramic tile adhesives and grouts can be used also fo
24、r other kinds of tiles (natural and agglomerated stones, etc.), where these do not adversely affect the materials. This standard can involve hazardous materials and operations. Persons using this standard shall be familiar with normal laboratory practice. This standard does not purport to address al
25、l the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any European and national regulatory conditions. 2 Normative references This draft European Standard incorporates, by dated
26、or undated reference, provisions from other publications. These 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 on
27、ly when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 1066, Adhesives Sampling. EN 1067, Adhesives Examination and preparation of samples for testing. 3 Sampling Take a test sample of at least 2 kg of the adhesive or
28、 grout in accordance with EN 1066 and EN 1067. 4 Test conditions Standard conditions shall be (232) 8C and (505) % relative humidity and a circulation of air in the testing area less than 0,2 m/s. 5 Test materials Condition all test materials other than the adhesive to be tested for at least 24 h un
29、der standard conditions. The adhesive to be tested shall be within its shelf life, where this is specified. 6 Apparatus 6.1 Mould The mould shall be a right cylinder (251) mm in diameter by (251) mm high. The mould shall be constructed in any manner that allows the formation of the desired test spec
30、imen. Typical moulds consist of a (251) mm thick flat plastic board in which (251) mm diameter holes have been cut, and to the bottom of which a flat and smooth plastic sheet, at least 6 mm thick, without holes, which is attached by means of screws or any other suitable system. Alternatively, the mo
31、ulds shall consist of sections of round plastic tubing or pipe, (251) mm in inside diameter, and (251) mm long, with sufficient wall thickness to be rigid and retain dimensional stability during the moulding operation, and a 6 mm thick flat plastic sheet on which one open end of each section shall b
32、e able to be rested. NOTEThe material from which the mould is constructed should be chemically inert and have antistick properties. Polyethylene, polypropylene, polytetrafluoroethylene and metal forms having a sintered coating of tetrafluoroethyiene polymer have been found satisfactory. 6.2 Containe
33、rs 6.2.1 Wide mouth jars of sufficient capacity, fitted with plastic or plastic-lined metal screw caps for low temperatures tests involving media of low volatitlity. 6.2.2 Erlenmeyer flasks, of sufficient capacity, fitted with standard-taper-joints and a reflux condenser attachment for use with vola
34、tile media. 6.2.3 Containers, as described in 6.2.1 and 6.2.2, of a suitable inert material for use with media which attack glass. 6.3 Compression machine A test machine with suitable capacity and sensitivity for the test and with a variable testing speed. The machine shall be capable of applying th
35、e compression load to the specimen through a suitable compression jig designed to provide self-alignment with specimen. 6.4 Chemical agent The chemical agent shall consist of the media to which the chemical resistant materials are to be exposed in service. 7 Test specimen 7.1 Number The number of sp
36、ecimen required is dependent upon the number of test media to be employed, the number of different temperatures at which testing is performed and the frequency of test intervals. In any case the test specimen shall consist of sets of a minimum of three cylinders for one medium, at a single temperatu
37、re and for each test interval. In addition one set of at least three specimens shall be available for test immediately following the conditioning period, and other sets of at least three, equivalent to the number of test temperatures, for the total test period. Calculate the total number of specimen
38、 required as follows: N = n (MTI) + nT + n where Nis the number of specimen; nis the number of specimen for a single test; Mis the number of media; Tis the number of test temperatures; Iis the number of test intervals.

39、ncontrolled Copy, (c) BSI Page 4 EN 12808-1:1999 BSI 12-1999 7.2 Dimension The test units shall be cast right cylinders, (251) mm in diameter by (251) mm high, with flat smooth faces normal to the axis of the cylinder, prepared in moulds described in 6.1 and employing no release agent in the mould.
40、7.3 Preparation Mix the components in the ratio specified by the manufacturers instructions. Blend the parts using a suitable hand tool or machine mixer, ensuring that any ingredients are thoroughly and uniformly mixed. Place the product in the mould with a spatula, taking care to ensure complete fi
41、lling of the mould cavity without entrapment of air. Scrape off the excess material with a flat trowel, making the exposed surface as smooth and even as possible. Permit the material to remain in the mould until it has set sufficiently to allow removal without danger of deformation or breakage. 7.4
42、Conditioning Condition the test units for seven days in standard conditions, seven days includes the mixing time in the mould. After the seven days proceed as described in 8.5 on one set of specimens. 8 Procedure 8.1 Immediately following the conditioning period measure the diameter of all test spec
43、imen to the nearest 0,03 mm using a micrometer. Make two measurements at right angles to each other and record the diameter as the average of the two. Following the diameter measurement weigh all the specimen to the nearest 0,001 g on an analytical balance and record the values. Prior to immersion r
44、ecord a brief description of the colour and surface appearance of the specimen and of colour and transparency of the test medium. 8.2 Place the weighed specimen, to be immersed, on their curved sides into the container (6.2) taking care to prevent the cylinder faces coming in contact with each other
45、. The total number of specimen per container is only limited except by the ability of the container to hold the specimen plus the required amount of test medium per specimen. 8.3 Add (1005) ml of the chemical agent for each specimen and place the closed container in a constant-temperature oven adjus
46、ted to the required temperature or in a suitably adjusted liquid bath simulating the actual service and exposure as closely as possible. Replace agents that are known to be unstable, as often as necessary, in order to maintain the original chemical composition and concentration, for the planned inte
47、rvals. 8.4 Remove the specimen after 28 days of immersion to determine the chemical attack. If necessary employ other exposure periods. Clean the specimen by three quick rinses in running cold tap water and quick dry by blotting with a paper towel between each rinse. After the final blotting allow t
48、he specimen to dry for 30 min, resting on its curved surface, weigh to the nearest 0,001 g and measure the diameter of the test specimen as described in 8.1. Note any indication of surface attack on the specimen, any discoloration of the test specimen and the formation of any sediment. 8.5 Determine
49、 the compressive strength for one set of specimens: immediately after the conditioning period; after the exposure period for each chemical agent and each temperature; after ageing in air for the total test period at each test temperature. The elapsed time between the removal of the specimen from the test medium and the compressive test should be uniform for all specimens. Place each specimen in the testing machine with the plane faces of the cylinder in contact with the surface of the compre
