22、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of an identical text or by endorsement, at the latest by April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. Attention is drawn to the possibility that some of th

23、e elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14706:2005. The main technical changes that have been made in this new edition of EN 14706 are the following: a

24、) Normative references have been updated; b) Figure 1 has been corrected; c) Clause 9, Accuracy of measurements has been revised; d) 5.1, Flat square or circular hot plate has been supplemented; e) 6.1, Dimensions of test specimens has been revised; f) A.3.1, Test conditions has been revised; g) A.5

25、, Test for internal self-heating has been completed; h) C.4, Additional tests and/or observations has been completed; i) D.3, Dimensions of test specimens has been revised. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of

26、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 provisions of the Member States relating to cons

27、truction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been prepared for products used to insulate building equipment and industrial installations, but it may also be applied to products used in other areas. A similar standard is

28、available for testing of preformed pipe insulation EN 14707, Thermal insulating products for building equipment and industrial installations Determination of maximum service temperature for preformed pipe insulation. According to the CEN/CENELEC Internal Regulations, the national standards organisat

29、ions of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malt

36、re at which the insulation product, when installed at the recommended thickness in a given application, continues to function within specified limits of performance SOURCE: EN ISO 9229:2007, 2.6.9.1 Note 1 to entry: The required performance may be in the areas of dimensional stability, thermal prope

37、rties, and mechanical properties as well as changes in appearance and resistance against creation of hazards such as internal self heating (see Annexes A and C and possible requirements in the relevant product standard). Note 2 to entry: In the present test procedure, which is used as a reference, t

38、he test specimen is exposed to a temperature difference going from ambient to the maximum service temperature. This may not reflect the actual application conditions when products are exposed to different temperatures on the two main faces, e.g. in multilayer systems or for faced products where the

39、facing may limit the maximum service temperature. 4 Principle Measure thickness, length, and width after one sided heat treatment for a specified time period, at the maximum service temperature, achieved using a specified rate of temperature increase. The thickness of the test specimen is measured d

40、uring heat treatment, and the length and width only after cooling to ambient temperature. The procedure may be an iterative process. DIN EN 14706:2013-01 EN 14706:2012 (E) 6 Additional requirements for assessing the maximum service temperature of specific materials are described in normative annexes

41、 to this European Standard or the relevant product standard or any other European Technical Specification. 5 Apparatus A general arrangement of the apparatus is indicated in Figure 1 and comprises: 5.1 Flat square or circular hot plate, with a uniform temperature distribution in the measuring zone o

42、n the hot face and a heat flux perpendicular to the face of the hot plate. The deviation from flatness of the hot plate shall not exceed 1 mm in the measuring zone at ambient temperature. The hot plate shall be capable of being controlled to within 2 % of a predetermined temperature or 10 C, whichev

43、er is smaller. The hot plate shall be capable of being heated at 50 C/h and/or 300 C/h. If a small size equipment (e.g. 100 mm) is used, the free movement of the test specimen during the test is critical and shall be controlled strictly. 5.2 Edge insulation, with a gap as small as possible (e.g. 1 m

44、m/100 mm test specimen size) which will permit free movement during the test of the test specimen and of the pressure plate. 5.3 Square or circular pressure plate, with the same dimensions as the test specimen exerting the required load on the test specimen. 5.4 Device, e.g. electromechanical, for m

45、easuring the thickness of the test specimen during the test to the nearest 0,1 mm. When determining the thickness of the test specimen, the thermal movement of the apparatus (e.g. quartz rod) shall be taken into account up to the maximum service temperature. 5.5 Temperature sensors (e.g. thermocoupl

46、es) capable of recording the hot plate temperature to the nearest 1 % in centigrade but not less than 1 C, which are placed within grooves on the hot plate.
