DIN EN 12090:2013-06EN 12090:2013 (E) 5 1 Scope This European Standard specifies the equipment and procedures for d
32、etermining shear behaviour. It is applicable to thermal insulating products. NOTE The tests described in this standard do not determine pure shear behaviour, but measure the effects of applying two opposite parallel forces to the major faces of the test specimen. The test is however called shear in
33、this text by convention. The application of a force tangentially to the major surface of the test specimen is considered to represent more closely the stresses imposed upon thermal insulation products in many building applications, particularly walls, than other methods of measuring shear performanc

36、ce applied to the product, which will cause rupture along a plane parallel to the direction of the applied force, to the area of the plane on which the force acts 3.2 shear modulus, G shear stress divided by the corresponding relative deformation below the proportional limit, when the relationship i
37、s linear Note 1 to entry: See Figure 3. 4 Principle A test specimen is subjected to a shear stress transmitted to the test specimen through rigid supports to which it is bonded. The corresponding force-displacement curve is determined. NOTE Tests carried out using the single test specimen method hav
38、e produced results for shear strength, which indicate the result to be dependent upon test specimen thickness, with more scattered results at greater thicknesses. Tests using the double test specimen method have also shown test specimen thickness to influence results for shear strength. 5 Apparatus
39、5.1 Test machine 5.1.1 General A test machine capable of applying a sufficient force within the maximum displacement experienced in the shear test. It shall be capable of operating at a constant rate of movement of the movable head of (3 0,5) mm/min in a direction parallel to the longitudinal axis o
40、f the test specimen assembly. DIN EN 12090:2013-06EN 12090:2013 (E) 6 The test machine shall exert a force F on the test specimen with a maximum error of 1 %, and produce a displacement , of the movable support relative to the fixed supports, having a maximum error of 1 %. If the shear modulus is re
41、quired, the force F and the displacement shall be simultaneously recorded to provide the curve of F, required in Clause 7. It may be necessary to use a displacement transducer for accurate measurement of deformation particularly where a thick adhesive layer has been used in preparing the test specim
42、en. The null or zero displacement of the test specimen may be calculated by subtraction from , the displacement due to the equipment and the same thickness of adhesive measured without the test specimen, e.g. replace the test specimen by metal block(s) in a blank test. 5.1.2 Single test specimen arr
43、angement The test machine shall exert longitudinal shear forces through parallel plates bonded to a single test specimen of dimensions as in 6.1.2. The parallel plates shall be rigid with one plate attached to the fixed and the other to the movable parts of the test machine. 5.1.3 Double test specim
44、en arrangement The test machine shall exert longitudinal shear forces through parallel plates bonded to a double test specimen of dimensions as in 6.1.3. The parallel plates shall be rigid with the outer plates attached to the fixed and the central plate to the movable parts of the test machine. 5.2
45、 Specimen supports 5.2.1 Single test specimen assembly Two flat rigid specimen supports of length 330 mm and width 50 mm which shall be attached to the grips of the test machine via an adaptor and universal joint. The method of attaching the specimen supports to the grips is shown in Figure 1. The t
46、hickness of the adaptors that connect the specimen supports to the test machine grips shall be the same as the thickness of the test specimen. Flat rectangular sectioned mild steel plates with a thickness of 16 mm have proved suitable for the support material. 5.2.2 Double test specimen assembly The
47、 essential features are three flat rigid supports of which two can be maintained with their planes parallel and vertical. Two suitable arrangements are shown in Figure 2. Experience gained using both the single and double test specimen methods with several products indicated that it is of paramount
48、importance that the specimen supports are very rigid. With the double test specimen arrangement, the fixed supports should be maintained in parallel vertical planes. Both the arrangements shown in Figure 2 have proved suitable. 5.3 Adhesive The adhesive used to fix the test specimen shall be such that the shear strength and modulus of the adhesive film is greater than that of the product under test. This ensures that rupture occurs
