22、ion of plastic and rubber sheets as manufactured or supplied before use. This test method relates exclusively to products, or to their components where appropriate, and not to waterproofing membrane systems composed of such products and installed in the works. This test is intended to be used in con

23、junction with EN 13956, Flexible sheet for waterproofing Plastic and rubber sheets for roof waterproofing Definitions and characteristics. Only testing by immersion of the entire surface of the test specimen is considered. The methods for determination of changes in properties are specified as follo

24、ws: a) changes in mass immediately after immersion or after immersion and drying; b) changes in appearance immediately after immersion or after immersion and drying; c) changes in physical properties (changes of tensile properties) immediately after immersion or after immersion and drying. Tests imm

25、ediately after immersion are used when it is required to ascertain the state of the material while still acted upon by the liquid. Tests after immersion and drying are used when it is required to ascertain the state of the material after the liquid, if it is volatile, has been eliminated. Licensed C

27、luding water), and methods for determining the changes in properties resulting from such exposure. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the lates

Determination of the properties b

31、efore and after immersion and, if applicable, after drying. In the latter case the determinations are made, if possible, one after the other on the same specimens. 5 Apparatus 5.1 Container Beakers of suitable dimensions and fitted with lids (airtight, if necessary, and fitted with condensers in the

32、 case of volatile liquids or those which give off vapours). 5.2 Enclosure Enclosure which is thermostatically controlled at the test temperature. 5.3 Thermometer Thermometer of suitable range and accuracy.

34、. For drying purposes, the oven shall be controlled at (50 2) C. 6 Sampling Samples shall be taken in accordance with EN 13416. 7 Preparation of test specimens Depending on the proposed test after exposure (mass, physical properties) and the nature of the plastic or rubber roof waterproofing sheet,

35、the specimens will be of very diverse shapes and dimensions. For sheets with an inner layer or reinforcement it is recommended to seal the edges of the specimens before immersion in a test liquid. The number of specimens to be used will be specified by the methods to determine the properties before

36、and after exposure. In the absence of any other instructions, at least three specimens shall be tested. Condition the test specimens, prior to testing, for at least 24 h in a standard atmosphere of (23 2) C and (50 5) % relative humidity. 8 Procedure 8.1 Test liquids If information is required about

37、 the behaviour of the sheet in contact with a specific liquid that liquid shall, wherever possible, be used. The test shall be carried out with defined chemical products, used on their own or as a mixture; the test should be as representative as possible of the effect on the waterproofing sheets. Fo

38、r general evaluations of materials behaviour when exposed to aqueous liquids the specimens shall be stored in aqueous solutions as shown in Table 1 as specified in Table A.1 of EN ISO 175:2000.

40、chnically pure) If other liquids need to be agreed on for exposure there are listings of laboratory chemicals available, for example EN ISO 175:2000. If necessary a stirrer may be used. 8.2 Temperature The standard immersion temperature is (23 2) C. For other temperatures consult the applicable prod

41、uct standard. The temperature for the determination of changes in properties is (23 2) C. If the immersion temperature is different, bring the specimens to ambient temperature by transferring them into a fresh quantity of test liquid at room temperature for 15 min to 30 min. 8.3 Exposure durations A

42、ny practicable exposure duration, representative of the phenomenon to be evaluated, may be applied. The standard exposure duration for comparison tests is 28 days. For other durations consult the applicable product standard. 8.4 Immersion procedure 8.4.1 Quantity of test liquid The quantity of test

43、liquid used shall be at least 2500 ml for 1 or more samples with maximum total dimensions of (210 x 295) mm. The test liquid shall completely cover the specimen. 8.4.2 Positioning of specimens Place each set of test specimens in a given container and completely immerse them in the test liquid (using

44、 a weight if necessary). When several materials of the same composition are to be tested, several sets of specimens may be put into the same container. Any contact between different specimens shall be avoided with a minimum distance of 10 mm at the beginning. If light is likely to have influence on

45、the action of the test liquid, it is recommended to operate either in darkness or in defined illumination conditions. It is recommended to use closed containers.

46、 Rinsing and wiping Remove the specimens from the test liquid and rinse them with a product which has no effect on the material under test and which is chosen to suit the nature of the test liquid. Wipe the specimens dry with filter paper or a lint free cloth. If elevated temperature is used during

47、exposure, at the end of the period of immersion, bring the temperature of the specimens back to ambient temperature if necessary, by transferring them quickly into fresh quantity of test liquid at room temperature, for a period of 15 min to 30 min. 8.5 Determination of changes in mass 8.5.1 Test spe

48、cimen The test specimen shall have the shape and dimensions specified in EN 1849-2 for the determination of mass per unit area. Prepare the number of specimens to determine the mass per unit area according to EN 1849-2. If elevated temperature is used during the exposure, prepare additional specimen

49、s to serve as a control of any temperature influence. Control of other influences shall require additional quantities of specimens. 8.5.2 Initial value Determine the initial mass M1 of each specimen to the nearest 0,001g in the case of specimens of mass greater than or equal to 1 g following EN 1849-2. 8.5.3 Exposure Immerse the test specimens in the test liquid at the chosen temperature for the chosen period, following the
