16、of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2002, and conflicting national standards shall be withdrawn at the latest by March 2002. This European Standard is on

17、e 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 app

18、roximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 8911 OG/EEC) through the consideration of the essential requirements. This European Standard has been prepared for products used to insulate building equipment and industri

19、al installations, but it may also be applied to products used in other areas. No existing European Standard is superseded According to the CENICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium

20、, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 13471:2001 (E) i Scope This European Standard specifies the equipment and procedures for determining the coefficien

21、t of linear thermal expansion. The standard is applicable to thermal insulating products within the temperature range - 196 OC to 850 OC, subject to the possible temperature limitation of the test specimens. It shall not be used for products which during the test experience dimensional changes due t

22、o the loss of hydration water or which undergo other phase changes. NOTE Because of its small dimensions the test specimen should be carefully selected to be representative of the product being tested. 2 Normative references This European Standard incorporates, by dated or undated reference, provisi

23、ons from other publica-tions. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it b

EN 12085, Thermal insulating products for building applications - Determination of linear dimensions of test specimens. 3 Terms and definitions For the purpose of this Eu

25、ropean Standard, the following terms and definitions apply: 3.1 linear thermal expancion reversible changes in the length of a product resulting from a change in temperature 3.2 mean coefficient of linear thermal expansion a, between different temperatures reversible change in length divided by the

26、length at the reference temperature and the temperature difference between the test tem peratures 3.3 coefficient of thermal expansion 4 at the temperature T limit value of % as the higher temperature approaches the lower temperature (see Figure 1) NOTE The definition of 12 is the length of the test

27、 specimen, in millimetres, at the temperature T2. in degree Celcius. If required, determine the coefficient of thermal expansion at the temperature T, a, as the tangent to the above curve. 9 Accuracy of measurement NOTE It has not been possible to include a statement on the accuracy of the method in

28、 this edition of the standard, but it is intended to include such a statement when the standard is next revised. 10 Testreport The test report shall include the following information: a) reference to this European Standard; b) product identification 1) product name, factory, manufacturer, or supplie
