This European Standard shall be given the status of a national standard, either by publication of an identical text or
16、by endorsement, at the latest by September 2013, and conflicting national standards shall be withdrawn at the latest by September 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsib
17、le for identifying any or all such patent rights. This document supersedes EN 12430:1998. The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test methods for d
18、etermining 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 approximation of laws, regulations and administrative provisio
19、ns 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 areas where it is relevant. This European test standard is
20、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 products for building applications Determination of length and widt

DIN EN 12430:2013-05 EN 12430:2013 (E) 5 1 Scope This European Standard specifies equipment and procedures for determining the behaviour of products under a force applied to a small area of a test specimen at a given speed. It is applicable to thermal i
33、nsulating 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, mainly caused by pedestrian traffic. NOTE The test methods given in the main body of the st
34、andard and in Annex A are reported and interpreted in different ways. The similarities that exist between the methods are not sufficient to permit reasonable comparisons to be made. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and a

38、ntry: 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 at the critical point and/or the force for a given deformation is calculated. 5 Apparatu
39、s 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 side (or the diameter) is at least as large as the length (or the diagonal length) of t
40、he 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. DIN EN 12430:2013-05 EN 12430:2013 (E) 6 If appropriate, the indentor shall be connected to the compression machine through a centrally positioned
41、 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 2 and 3).

This sensor shall be such
44、 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 measurement of the force permitting reading to 1 %. 5.5 Recording device, for th

Any skins, facings, and/or coatings shall be retained. The test specim
46、ens shall be squarely cut and square with sides having dimensions of 300 mm 300 mm. Other dimensions may be specified in the relevant product standard or any other European Technical Specification or may be agreed between parties. The linear dimensions shall be determined in accordance with EN 12085

The test specimens shall be cut and prepared by methods that do not change the 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 specime
