For dated references, only the edition cited

17、applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

18、nts ISO 554, Standard atmospheres for conditioning and/or testing Specifications 3 Terms and definitions For the purposes of this document, the terms and definitions given in FprEN 15814:2011 apply. 4 Principle After coating the substrate and conditioning the test specimen is placed in a test rig. A

19、fter then the surface of the coated substrate is stressed with a constant load till a stabilization of the reduction of thickness is reached. 5 Apparatus 5.1 Flat base with a diameter equal to or greater than 10 mm (accuracy of 10 m) to measure the thickness of layers prior to loading. 5.2 Test rig,

20、 capable of exerting a constant pressure on a surface over an extended period of time. 5.3 Extensometer or vernier calliper (accuracy of 10 m), measuring marks, micrometer. 5.4 Metal or a plastic frame or a screed template. 5.5 Concrete support/loading platens with an area greater or equal than 20 c

21、m 20 cm and with a thickness greater or equal than 4 cm thick, minimum 28 days old, minimum quality C 20/25 in accordance with EN 206-1. The upper and lower surfaces of the support/platens are ground so as to be flat and parallel to each other. 6 Test specimens 6.1 General Squared test specimen with

22、 a size of approximately 20 cm 20 cm. BS EN 15815:2011EN 15815:2011 (E) 5 6.2 Preparation The supports and the components of the polymer modified bituminous thick coatings shall be conditioned prior to the preparation of the specimens in a normal climate of (23 2) C and a relative humidity of (50 5)

23、 % in accordance with ISO 554 for at least 24 h. The polymer modified bituminous thick coating shall be prepared at room temperature as specified by the manufacturer of the product and applied to the ground surface of the concrete support over an area of 20 cm 20 cm, also at a room temperature. The

24、thickness of the wet layer shall be such that the thickness of the dry layer corresponds to that specified by the manufacturer for each type of use after drying (at least 3 mm or 4 mm) within a tolerance of 10 %. A frame of the appropriate height or screed template, in which the layer is struck off,

25、 shall be used to obtain the required thickness. The specimens shall be left to dry in a normal climate of (23 2) C and a relative humidity of (50 5) % in accordance with ISO 554 for 28 days prior to testing. 6.3 Dimensions of the test specimens The thickness of the dry layer shall be measured using

26、 vernier callipers permitting a reading to 0,1 mm. 12 readings shall be taken. The highest and lowest values shall be ignored and the mean value calculated from the remaining 10 values. 6.4 Conditioning of test specimens The test specimens shall be stored for at least 28 days at a normal climate (23

27、 2) C and a relative humidity of (50 5) % prior to testing. 7 Procedure 7.1 Test conditions The test shall be carried out at (23 2) C. 7.2 Procedure The thicknesses of the layer shall be determined at sixteen measuring points distributed evenly over the surface of the specimen, but at a distance of

28、not less than 2 cm from the edges of the specimen The mean thickness of the dry layer shall then be determined (Sv). A minimum of three specimens shall be tested in each test. Several specimens may be stacked and tested simultaneously for convenience. The surface of the coating shall be prevented fr

29、om adhering to the support of the specimen above it or to the loading platens by inserting a suitable separating layer (e.g. silicone-coated paper) between the specimens. Specimens tested simultaneously shall be placed in a suitable test rig to prevent any lateral displacement of the specimens occur

30、ring during the test and to ensure an evenly distributed application of force over the entire surface of the specimens. Two gauge marks shall be made on the four sides of the specimen supports and loading platens at a distance of one third of the side length from the edges to enable the mean change

31、in the thickness of the layers of each specimen during the test to be determined. BS EN 15815:2011EN 15815:2011 (E) 6 After the specimens have been mounted in the test rig, the distance between the gauge marks on each specimen shall be measured to 10 m. A preliminary load of 0,01 MN/m shall then be

32、applied. The distances between the gauge marks shall be measured again immediately afterwards. The mean change in the thickness of each specimen (S0) shall be determined from the differences between individual measurements. The thickness of the layers at the start of the test (S0) is therefore: 0v0-

33、 SSS = (1) where S0is the thickness of the layer at the start of the test, in millimetre (mm); Svis the mean thickness of the dry layer, in millimetre (mm); S0is the mean change of the thickness, in millimetre (mm). The main load is then applied in accordance with FprEN 15814. The layer thickness of

34、 each specimen shall be measured daily. The test is deemed to have been passed if the mean change in the thickness of each specimen after 5 days (S5) is less than 50 % of the initial thickness of the layer and the difference between the changes over the last three days, e.g. between the 2ndday and 5

35、thday (S5 S2), does not exceed 3 % (stabilisation). If the change over three days exceeds 3 %, the test can be extended up to a maximum of 40 days or until the change over three days (Sn Sn-3) is 3 % for an overall change of 50 %. All three specimens shall fulfil these requirements. 8 Expression of

36、results and precision 8.1 Expression of results The mean deviation of the thickness of each specimen (Sn) from the initial thickness (S0) at each measurement n is expressed as the relative change in the thickness of the layer Sn. ()100/0nn= SSS (2) where Snis the relative change of the thickness of

37、the layer, in percent (%); Snis the mean deviation of the thickness of each specimen, in millimetre (mm); S0is the initial thickness, in millimetre (mm). The test results for each specimen shall be recorded (or plotted, as required) over time and analysed. 8.2 Precision Precision data are currently

38、not available.
