33、ending behaviour of full size products (Method A) and test specimens (Method B) under the action of three-point loading. It is applicable to thermal insulating products.

34、 determine the resistance of the product to bending stresses during transport and application. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、method consists of applying, at a given speed, a force by means of a loading edge in an axial direction to the faces of a squarely cut rectangular test specimen, which is placed on two support edges. The force is applied to the test specimen at a position midway between the supporting positions (see
40、 Figure 1). a) Bending strength b) Deflection Figure 1 Principle of test method 5 Apparatus 5.1 Test machine A test machine suited to the range of force and displacement involved, and with a loading edge and adjustable support edges. It shall be capable of operating at a constant rate of movement of
41、 the movable head. 5.1.1 Support edges Test specimen supports shall consist of two adjustable cylindrical support edges placed parallel to each other and in the same horizontal plane. The diameter of the supports shall be (80 3) mm or (30 3) mm (see Figure 2). The length of the support edges shall b
42、e at least equal to the width of the test specimens. The span L (see Figure 2) between the support edges shall be adjustable in the range 300 mm to 1 200 mm (method A) or 200 mm to 500 mm (method B). 5.1.2 Loading edge The test specimen loading edge shall have the same shape and dimensions as the su
43、pport edges. The loading edge shall be located centrally between and parallel to the supporting edges. 5.1.3 Load distribution plates For products which may be subject to crushing by the loading and support edges, steel load distribution plates with a thickness of at least 1 mm shall be used. The wi
44、dth of the distribution plates shall be (30 1) mm and their length shall be at least equal to the width of the test specimen. DIN EN 12089:2013-06 EN 12089:2013 (E) 7 5.2 Measuring devices for displacement and force 5.2.1 Measurement of displacement The test machine shall be fitted with a system tha
45、t allows continuous measurement of the displacement of the movable loading edge with an accuracy of 5 % or 0,1 mm, whichever is the smaller. The measured displacement corresponds to the deflection, X, of the test specimen. 5.2.2 Measurement of force A force sensor shall be fixed to the loading edge
46、in order to measure the force F produced by the reaction of the test specimen upon the edges during the test. This sensor shall be such that its own deformation during the course of the measuring operation is negligible compared with that being measured or may be taken into account by calculation. I
47、n addition, it shall allow the continuous measurement of the force at all times permitting reading to 1 %. A device shall be used for the simultaneous recording of the force, F, and the deflection, X, to provide the force-deflection curve, required in Clause 7. 1 loading edge 2 test specimen with th
