It supports a series of product standards for thermal insulating materials and products which derive from the Council D
16、irective of 21 December 1988 on the approximation 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 buil
17、dings but it may also be used in other 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

30、plied to a small area of a test specimen at a given speed. It is applicable to thermal insulating products. This European Standard can be used to determine whether the products have sufficient strength to withstand forces applied directly to them either during installation or during application, mai

The similarities that exist between the methods are not sufficient to permit reasonable comparisons to be made. 2 Normative references The fol

34、erms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 point load compressive force applied to a test specimen by a circular indentor with a circular cross section of 50 cm2(diameter 79,8 mm) 3.2 critical point point on the force-deformation curve, whe
35、re a straight line, forming a tangent to the curve, separates from the curve Note 1 to entry: See Figure 4a). 4 Principle A point load is applied with an indentor at a given speed in an axial direction perpendicular to the major faces of a squarely cut square test specimen and the compressive force
36、at the critical point and/or the force for a given deformation is calculated. 5 Apparatus 5.1 Compression testing machine, appropriate to the range of force and displacement involved and having one rigid, polished, fixed or vertically movable square or circular plane plate of which the length of one
37、 side (or the diameter) is at least as large as the length (or the diagonal length) of the test specimen (see Figure 1). 5.2 Cylindrical indentor, steel, having a diameter of (79,8 0,1) mm, connected to a vertically movable or fixed support. BS EN 12430:2013EN 12430:2013 (E) 6 If appropriate, the in
38、dentor shall be connected to the compression machine through a centrally positioned ball joint to ensure that only axial force is applied to the relevant area of the test specimen. The indentor or the supporting plate shall be capable of moving at a constant speed in accordance with 7.2 (see Figures
39、 2 and 3).

40、ng device, capable of continuous measurement of the displacement of the indenter or the movable plate, permitting a reading to 5 % or 0,1 mm, whichever is the smaller (see 5.1.1). 5.4 Force-measuring sensor, fitted to the machine plate or the indenter, to measure the force produced by the reaction o
41、f the test specimen upon the plate and the indenter. This sensor shall be such that its own deformation during the course of the measuring operation is negligible compared with that being measured or if not, it shall be taken into account by calculation. In addition, it shall allow the continuous me
42、asurement of the force permitting reading to 1 %. 5.5 Recording device, for the simultaneous recording of the force F and the displacement X which provides a curve of F as a function of X (see 7.2). 6 Test specimens 6.1 Dimensions of test specimens Test specimens shall be at the original product thi

Other dimensions may be specified in the relevant product standard or any other European Technical Specification or may be agreed between
44、parties. The linear dimensions shall be determined in accordance with EN 12085, to the nearest millimetre. The tolerance on parallelism and flatness between the two major faces of the test specimens shall not be greater than 0,5 % of the test specimen side with a maximum of 0,5 mm. BS EN 12430:2013E
45、N 12430:2013 (E) 8 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. If the number is not specified, then at least three test specimens shall be used. In the absence of a product standard or any other European Technical Specification th
46、e number of test specimens may be agreed between parties. 6.3 Preparation of test specimens Test specimens shall be cut so that the specimen base is normal to the direction of compression of the product in its application. The test specimens shall be cut and prepared by methods that do not change th
47、e original structure of the product. Moulded skins that do not remain with the product in use shall be removed. Rectangular test specimens with parallel major faces shall be cut from the product so that the test specimen base is normal to the direction of the force which is experienced in its applic
48、ation. 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 they shall be stored at (23 2) C and (50 5) % relative humidity for the time specified in the relevant product standard. 7 Procedure 7.1 Test conditions The test shall be car
49、ried out at (23 5) C. In case of dispute it shall be carried out at (23 2) C and (50 5) % relative humidity. 7.2 Test procedure Measure the linear dimensions to the nearest millimetre in accordance with EN 12085. Place the test specimen in the compression testing machine on the fixed plate so that the indentor is centrally located above the test specimen (see Figure 1). Preload with a force of (2,5 0,25) N corresponding to a pressure of
