The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is o
17、ne of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the ap
18、proximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in buildings but it may also be used in other
19、 areas where it is relevant. This European test standard is one of the following group of interrelated standards on test methods for determining dimensions and properties of thermal insulation materials and products, all of which fall within the scope of CEN/TC 88: EN 822, Thermal insulating product

33、ferenced document (including any amendments) applies.

34、f the product under a load of 250 Pa 3.2 thickness dFthickness of the product under a load of 2 kPa 3.3 thickness dBthickness of the product under a load of 2 kPa after application of a short time additional load (48 kPa) 4 Principle The thickness is determined as the distance measured between a rig
35、id 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 Apparatus 5.1 Dial gauge, which permits reading to 0,1 mm, mounted on a rigid frame fastened to a rigid flat base plate. 5.2 Device, w
36、ith the same accuracy with two readings of the thickness/deformation placed symmetrically on a diagonal on the upper square plate of the device. The mean of these two readings is the thickness/deformation. 5.3 Base plate and pressure plate, which shall be at least as large as the test specimen. 5.4
37、Device, which exerts a total pressure on the test specimen of (250 5) Pa (including the force exerted by the dial gauge). DIN EN 12431:2013-05 EN 12431:2013 (E) 6 5.5 Device, which exerts a total pressure on the test specimen of (2 000 20) Pa (including the force exerted by the dial gauge). 5.6 Devi
38、ce, which exerts a total pressure on the test specimen of (50 000 500) Pa. Alternative to 5.1 through 5.6, a compression testing machine suited to the range of force and displacement involved can be used. The compression testing machine shall have two very rigid, polished, square plane parallel plat
39、es of which the length of one side is at least as large as the test specimen 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 is applied to the test specimen. A device for measuring
40、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 by the reaction of the test specimen upon
41、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 measurement of the force permitting a reading into
42、1 %. When measurements are made on a movable plate and not in the axis, two sensors shall be used placed symmetrically versus the axis. The mean value of the two readings is used. 6 Test specimens 6.1 Dimensions of test specimens The thickness of the test specimens shall be the original product thic
43、kness. The test specimens shall be squarely cut and square having sides of (200 1) mm. The length and width shall be determined in accordance with EN 12085, with an accuracy of 1 mm. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. If
44、the number is not specified, then ten test specimens shall be used. 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 test specimens The test specimens shall be cut so that they do not in
45、clude 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 specimens The test specimens shall be stored for at least 6 h at (23 5) C. In case of dispute
46、they shall be stored at (23 2) C and (50 5) % relative humidity for the time specified in the relevant product standard. DIN EN 12431:2013-05 EN 12431:2013 (E)7 7 Procedure 7.1 Test conditions The test shall be carried out at (23 5) C. In case of dispute it shall be carried out at (23 2) C and (50 5
47、) % relative humidity. 7.2 Test procedure 7.2.1 General Figure 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 contac
48、t 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. The thickness may be measured with the dial gauge at two diagonally opposite corners or in the ce
