21、ee CEN/TC 88 “Thermal insulating materials and products”, the secretariat 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 April 2013, and conflicting national standards sh
22、all be withdrawn at the latest by April 2013.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 responsible for identifying any or all such patent rights. This document supersedes EN 14706:2005.
23、The main technical changes that have been made in this new edition of EN 14706 are the following: a) 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
24、, Dimensions of test specimens has been revised; f) A.3.1, Test conditions has been revised; g) A.5, 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 on
25、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
26、roximation 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 prepared for products used to insulate building equipment and industria
27、l installations, but it may also be applied to products used in other areas. A similar standard is 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 p
28、ipe insulation. According to the CEN/CENELEC Internal Regulations, the national standards organisations 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 Macedo
29、nia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

It is applicable t
31、o thermal insulating products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the reference
32、d document (including any amendments) applies.

35、Viscosity and viscometric fixed points Part 7: Determination of annealing point and strain point by beam bending 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 maximum service temperature highest temperature at which the insulation product,
36、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 properties, and mechanical properties as
37、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, the test specimen is exposed to a tem
38、perature 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 facing may limit the maximum service
39、 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 during heat treatment, and the length
40、 and width only after cooling to ambient temperature. The procedure may be an iterative process.

41、 6 Additional requirements for assessing the maximum service temperature of specific materials are described in normative annexes 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
42、in Figure 1 and comprises: 5.1 Flat square or circular hot plate, with a uniform temperature distribution in the measuring zone on 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 ambi
43、ent temperature. The hot plate shall be capable of being controlled to within 2 % of a predetermined temperature or 10 C, whichever 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 spec
44、imen during the test is critical and shall be controlled strictly. 5.2 Edge insulation, with a gap as small as possible (e.g. 1 mm/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 th
45、e same dimensions as the test specimen exerting the required load on the test specimen. 5.4 Device, e.g. electromechanical, for measuring 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 apparat
46、us (e.g. quartz rod) shall be taken into account up to the maximum service temperature. 5.5 Temperature sensors (e.g. thermocouples) 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.
