23、 of ceramic tiles and grouts. NOTE Ceramic tile adhesives and grouts can be used also for other kinds of tiles (natural and agglomerated stones, etc.), where these do not adversely affect the materials. WARNING - This European Standard can involve hazardous materials and operations. Persons using th

24、is standard should be familiar with normal laboratory practice. This European Standard does not purport to address all 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 Eur

25、opean and national regulatory conditions. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 1067, Adhesives - Examination and preparation of samples for testing EN ISO 15605, Adhesives Sampling (ISO 15605:2000) 3 Sampling Take a test sample of at least 2 kg of the adhesive or grout in accordance with EN ISO 15605 and EN 1067. 4 Test conditions Standard conditions shall b

27、e (23 2) C and (50 5) % relative humidity and a speed 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 under standard conditions. The adhesive to be tested shall be within its shelf life, where this is

28、specified. DIN EN 12808-1:2009-01 EN 12808-1:2008 (E) 5 6 Apparatus 6.1 Mould The mould shall be a right cylinder (25 1) mm in diameter by (25 1) mm high. The mould shall be constructed in any manner that allows the formation of the desired test specimen. Typical moulds consist of a (25 1) mm thick

29、flat plastic board in which (25 1) 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 moulds shall consist of sections of round plastic

30、tubing or pipe, (25 1) mm in inside diameter, and (25 1) 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 be able to be rested. NOTE The material from wh

31、ich the mould is constructed should be chemically inert and have antistick properties. Polyethylene, polypropylene, polytetrafluoroethylene and metal forms having a sintered coating of tetrafluoroethylene polymer have been found satisfactory. 6.2 Containers 6.2.1 Wide mouth jars of sufficient capaci

32、ty, fitted with plastic or plastic-lined metal screw caps for low temperatures tests involving media of low volatility. 6.2.2 Erlenmeyer flasks, of sufficient capacity, fitted with standard-taper-joints and a reflux condenser attachment for use with volatile media. 6.2.3 Containers, as described in

33、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 the compression load to the specimen through a s

34、uitable 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 specimen required is dependent upon the number o

35、f 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 temperature and for each test interval. In addition one

36、 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 required as follows: () nTnITMnN += (1) DIN E

37、N 12808-1:2009-01 EN 12808-1:2008 (E) 6 where: N is the number of specimen; n is the number of specimen for a single test; M is the number of media; T is the number of test temperatures; I is the number of test intervals. 7.2 Dimension The test units shall be cast right cylinders, (25 1) mm in diame

38、ter by (25 1) 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. 7.3 Preparation Mix the components in the ratio specified by the manufacturers instructions. Blend the parts using a suitable hand tool o

39、r 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 filling of the mould cavity without entrapment of air. Scrape off the excess material with a flat trowel, making the exposed surface as smo

40、oth 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 Conditioning Condition the test units for 7 days in standard conditions, 7 days includes the mixing time in the mould. After the 7 days,

41、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 specimens 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 t

42、wo. 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 record 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 wei

43、ghed 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. The total number of specimen per container is only limited by the ability of the container to hold the specimen plus the required amount of test

44、medium per specimen. 8.3 Add (100 5) ml of the chemical agent for each specimen and place the closed container in a constant-temperature oven adjusted to the required temperature or in a suitably adjusted liquid bath simulating the actual service and exposure as closely as possible. Replace agents t

45、hat are known to be unstable, as often as necessary, in order to maintain the original chemical composition and concentration, for the planned intervals. 8.4 Remove the specimen after 28 days of immersion to determine the chemical attack. If necessary, employ other exposure periods. DIN EN 12808-1:2

46、009-01 EN 12808-1:2008 (E) 7 Clean the specimen with three quick rinses in cold running tap water and quick dry by blotting with a paper towel between each rinse. After the final blotting allow the specimen to dry for 30 min, resting on its curved surface, weigh to the nearest 0,001 g and measure th

47、e 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 the compressive strength for one set of specimens: immediately after the conditioning period; after the

48、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 tes

49、ting machine with the plane faces of the cylinder in contact with the surface of the compression tool or cage. Apply the load to the specimen at a crosshead movement of (5,5 0,5) mm/min when the machine is running without load. Break the specimen and record the maximum load. 9 Evaluation and expression of results 9.1 Mass change Calculate to the nearest 0,01 % the percentage loss or gain in mass of the specimen during exposure for each examination period as follows: ()100/ = CCWW (2) where: W is the mass chan
