19、prepared by Technical Committee 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 conf

20、licting national standards shall be withdrawn at the latest by April 2013.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 docume

21、nt supersedes EN 14707:2005+A1:2007. The main technical changes that have been made in this new version of EN 14707 are: a) 6.1, Dimensions of test specimens has been modified; b) B.3, Dimension of test specimens has been completed. This European Standard is one of a series of European Standards whi

22、ch 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 approximation of laws, regulation

23、s 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 industrial installations, but it may al

24、so be applied to products used in other areas. A similar standard is available for testing of flat products: EN 14706, Thermal insulating products for building equipment and industrial installations Determination of maximum service temperature. According to the CEN/CENELEC Internal Regulations, the

25、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 Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

26、 Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 14707:2013-01 EN 14707:2012 (E) 4 1 Scope This European Standard specifies the equipment and procedures for determining the maximum ser

27、vice temperature for preformed pipe insulation. It is applicable to 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 ap

28、plies. For undated references, the latest edition of the referenced document (including any amendments) applies.

30、r the purposes of this document, the following term and definition applies. 3.1 maximum service temperature highest temperature at which the insulation product, when installed a the recommended thickness in a given application, continues to function within specified limits of performance SOURCE: EN

31、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 well as changes in appearance and resistance against creation of hazards such as internal self-heating (see annexes and requirements in the

32、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 temperature difference going from ambient to the maximum service temperature. This may not reflect the actual application conditions when products are exposed t

33、o different temperatures on the two main faces, e.g. in multi-layer systems or for faced products where the facing may limit the maximum service temperature. 4 Principle Measure thickness and length after one sided heat treatment for a specified time period, at the maximum service temperature, achie

34、ved using a specified rate of temperature increase. The thickness of the test specimen is measured during heat treatment and the length only after cooling to ambient temperature. The procedure may be an iterative process. Additional requirements for assessing the maximum service temperature of speci

35、fic 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 in Figure 1 and is comprised of: DIN EN 14707:2013-01 EN 14707:2012 (E) 5 5.1 Hot

36、 pipe, with a uniform temperature distribution in the measuring zone on the hot surface and a heat flux perpendicular to the surface of the pipe within the measuring zone (two pipes are required, with diameters that fulfil the requirements of 6.1). The hot pipe shall be linear to within 1 mm in the

37、measuring zone at ambient temperature. The hot pipe shall be capable of being controlled to within 2 % of a predetermined temperature 10 C whichever is smaller over the central 60 % of the total pipe length. The hot pipe shall be capable of being heated at 50 C/h and/or 300 C/h. 5.2 End insulation,

38、with a gap as small as possible between end insulation and guard piece of the test specimen (e.g. 3 mm) which will permit free movement during the test of the test specimen. 5.3 Temperature sensors, (e.g. thermocouples) capable of recording the hot surface temperature of the test pipe to the nearest

39、 1 % in centigrade but not less than 1 C, which are placed within grooves on the hot pipe. 5.4 Flexible metal foil, 3 pieces, (e.g. brass) capable of exerting a uniform pressure of 500 Pa on the upper surface of the test specimen along its testing length of (500 5) mm and the two end guards, length

40、(250 5) mm. The pressure shall be calculated using the area: e.g. the test length of 500 mm times the diameter of the hot pipe. 5.5 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 specim

41、en, the thermal movement of the apparatus (e.g. quartz rod) shall be taken into account up to the maximum service temperature.

44、imens a) Length: The test specimen, length (1 000 10) mm, shall be cut at right angles to its length to give two end guards, length each (250 5) mm, and a test length of (500 5) mm. b) Thickness: The thickness shall be 100 mm or the largest thickness below 100 mm available. c) Inside diameter: Two s

45、izes shall be tested, in the range 22 mm to 220 mm. The dimensions shall be as specified in the relevant product standard or annex to this European Standard. In the absence of a product standard or any other European Technical Specification, the dimensions may be agreed between parties. Testing may

46、be performed on multi-layer systems to simulate the conditions existing in the application. If the pipe insulation is cut from a homogeneous, isotropic flat product, then the maximum service temperature can be obtained from tests carried out on the flat product with similar properties in accordance

47、with EN 14706. 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 one test specimen for each size shall be used. DIN EN 14707:2013-01 EN 14707:2012 (E) 8 In the absence of a product standard

48、or any other European technical specification the number of test specimens may be agreed between parties. 6.3 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 or at least 24 h. 7 Procedure 7.1 Test conditions The initial tem
