EN 14707:2005+A1:2007 (E) 3 Foreword This European Standard (EN 14707:2005+A1:2007) has been 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of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. This document supersedes EN 14707:2005. This document includes Amendment 1, approved by CEN on 2007-10-28. The start and finish of text introduced or altered by amendment is indicated in the text by tags !". This European Standard is one of a series of European 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 approximation 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 industrial installations, but it may also 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 national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
EN 14707:2005+A1:2007 (E) 4 1 Scope This European Standard specifies the equipment and procedures for determining the maximum service temperature for preformed pipe insulation. It is applicable to thermal insulating products. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. !EN 12429, Thermal insulating products for building applications — Conditioning to moisture equilibrium under specified temperature and humidity conditions" EN 13467, Thermal insulating products for building equipment and industrial installations — Determination of dimensions, squareness and linearity of preformed pipe insulation EN 14706, Thermal insulating products for building equipment and industrial installations — Determination of maximum service temperature 3 Terms and definitions For the purposes of this European Standard, the following definition applies. 3.1 Maximum service temperature highest temperature to which a thermal insulation product may be exposed at a given thickness and at which it will continue to function within specified limits of performance [!EN ISO 9229"] NOTE 1 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 relevant product standard). NOTE 2 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 to 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, achieved 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. NOTE The procedure may be an iterative process. 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.
EN 14707:2005+A1:2007 (E) 5 5 Apparatus A general arrangement of the apparatus is indicated in Figure 1 and comprises of: 5.1 Hot 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 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, 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 ± 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 (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 specimen the thermal movement of the apparatus (e.g. quartz rod) shall be taken into account up to the maximum service temperature.

6 Test specimens 6.1 Dimensions of test specimens 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. Thickness: The thickness shall be 100 mm or the largest thickness below 100 mm available. Inside diameter: Two sizes shall be tested, one between 25 mm and 65 mm and the other between 85 mm and 220 mm. The dimensions shall be as specified in the relevant product standard or annex to this European Standard. NOTE 1 In the absence of a product standard or any other European Technical Specification, the dimensions may be agreed between parties. NOTE 2 Testing may 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 with EN 14706. 6.2 Number of test specimens The number of test specimens shall be
