25、This European Standard incorporates, by dated 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, subsequentamendments to or revisions of these publicatio
26、ns apply to this European Standard only when incorporated init by amendment or revision. For undated references the latest edition of the publication referred to applies.EN 12085, Thermal insulating products for building applications Determination of linear dimensions of test specimens.3 Definitions
27、For the purposes of this standard, the following definitions apply.3.1thickness, dLthickness of the product under a load of 250 Pa3.2thickness, dFthickness of the product under a load of 2 kPa3.3thickness, dBthickness of the product under a load of 2 kPa after application of a short time additional
28、load (48 kPa)4 PrincipleThe thickness is determined as the distance measured between a rigid flat base plate on which the test specimen rests and a rigid flat pressure plate exerting different specified pressures on the top surface of the test specimen.5 Apparatus5.1 Dial gauge, which permits readin
29、g to 0,1 mm, mounted on a rigid frame fastened to a rigid flat base plate.!A device with the same accuracy with two readings of the thickness/deformation placed symmetrically ona diagonal on the upper square plate of the device. The mean of these two readings is the thickness/deformation.5.2 Base pl
30、ate and pressure plate, which shall be at least as large as the test specimen.5.3 A device, which exerts a total pressure on the test specimen, of (250 5) Pa (including the force exerted by the dial gauge).5.4 A device, which exerts a total pressure on the test specimen, of (2 00020) Pa (including t
31、he force exerted by the dial gauge).5.5 A device, which exerts a total pressure on the test specimen of (50 000500) Pa.!Alternative to 5.1 through 5.5 a compression testing machine suited to the range of force anddisplacement involved can be used. The compression testing machine shall have two very
32、rigid, polished, square plane parallel plates of which the length of one side is at least as large as the test s pecimen side to be tested. One of the plates shall be fixed and the other movable, if appropriate, with a centrally positioned knee ball joint to ensure that only axial force isapplied to
33、 the test specimen.A device for measuring the displacement shall be fitted to the compression testing machine, which allows measurement of the displacement of the movable plate and which permits a reading to 0,1 mm.A sensor shall be fitted to one of the machine plates to measure the force produced b
34、y the reaction of the test specimen upon the plates. This sensor shall be such that its own deformation during the course of the measuring operation is negligible compared with that being measured. If not, it shall be taken to account by calculation. In addition, it shall allow continuous measuremen
35、t of the force permitting a reading into 1 %. Whe n measurements are made on a movable plate and not in the axis, two sensors shallbe used placed symmetrically versus the axis and then the mean value of the two measurements is used.6 Test specimens6.1 Dimensions of test specimensThe thickness of the
36、 test specimens shall be the original product thickness.The test specimens shall be squarely cut and square having sides of (200 1) mm.The length and width shall be determined inaccordance with EN 12085, with an accuracy of 1 mm.6.2 Number of test specimensThe number of test specimens shall be as sp
37、ecified in the relevant product standard. If the number is not specified, then ten test specimens shall be used.NOTE In the absence of a product standard or any other European technical specification, the number of test specimens may be agreed between parties.6.3 Preparation of the test specimensThe
38、 test specimens shall be cut so that they do not include product edges. The test specimens shall be prepared by methods that do not change the original structure of the product. Any skins, facings and/or coatings shall be retained.6.4 Conditioning of test specimensThe test specimens shall be stored
39、for at least 6 h at (235) 8C. In case of dispute they shall be stored at (232) 8C and (50 5) % relative humidity for the time specified in the relevant product standard.7 Procedure7.1 Test conditionsThe test shall be carried out at (23 5) 8C. In case of dispute it shall be carried out at (23 2) 8C a
40、nd(50 5) % relative humidity.7.2 Test procedure7.2.1 GeneralFigure 1, below, indicates the procedures to be followed for the determination of the test specimen thicknesses.7.2.2 Thickness, dLLay the test specimen on the rigid, flat and horizontal base plate ensuring that the measuring area is in con
41、tact with the base plate.Place the test specimens, if faced or coated on one side, with the facing or coating against the base plate.Load the test specimen with a device exerting a pressure of 250 Pa.Measure the thickness (120 5) s after placing the pressure plate in position, to the nearest 0,1 mm.
42、NOTE The thickness may be measured with the dial gauge at two diagonally opposite corners or in the centre of the pressure plate or using a measuring device (pin) forced through an opening in the centre of the pressure plate.7.2.3 Thicknesses dF and dBThe thicknesses dF and dB shall be determined on
43、 the same test specimens that were previously used for determining the thickness dL.Load the test specimens with a device exerting a pressure of 2 kPa. Measure the thickness dF (120 5) s after applying this pressure, to the nearest 0,1 mm. Apply an additional pressure of 48 kPa. Remove this addition
44、al pressure after (120 5) s.Measure the thickness dB to the nearest 0,1 mm(120 5) s or (300 10) s after removing the pressureof 48 kPa. The pause before measuring the thickness, either 120 s or 300 s, shall be as specified in the relevant product standard.NOTE In the absence of a product standard or
45、 any other European technical specification the pause time may be agreed upon between parties.8 Calculation and expression of resultsThe results for each thickness dL, dF and dB shall be the mean value of the respective measurements made on all test specimens, rounded to the nearest 0,1 mm.9 Accurac
46、y of measurementNOTE It has not been possible to include a statement on the accuracy of the measurements in this edition of the standard, but it is intended to include such a statement when the standard is next revised.Licensed Copy: London South Bank University, London South Bank University, Thu Jan 18 01:30:33 GMT+00:00 2007, Uncontrolled Copy, (c) BSI
