19、echnical Committee CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI. This Technical Specification has been prepared by ad hoc working group 40 (“Mounting and fixing in reaction to fire tests”) of Technical Committee CEN/TC 127 (“Fire safety in buildings”). This document
20、 has been prepared on request of the CEC as support for CEN Technical Committees involved in the production of technical specifications under the Construction Products Directive (CPD). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries
21、are bound to announce this CEN Technical Specification: Austria, Belgium, 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, Swe
22、den, Switzerland and United Kingdom. CEN/TS 15447:20064 Introduction The Essential Requirements of the CPD apply to the construction works. Interpretative documents have been produced to form a link between the Essential Requirements and the performance characteristics of construction products incor
23、porated in a permanent manner in construction works, i.e. in end-use application1. The Essential Requirement concerned in this document is “Safety in case of fire”, and from that requirement the reaction to fire performance of construction products only is considered. Technical specifications under
24、the CPD, such as product standards, deal with construction products and their reaction to fire performance. For the assessment of reaction to fire performance the technical specifications use a set of supporting fire standards through reference to the classification standard EN 13501-1. Five reactio
25、n to fire test methods have been developed for the purpose of testing construction products, including products incorporated within building elements. The procedure for classification is outlined in EN 13501-1 providing a choice of Euroclasses. Since EN ISO 1182 (“non-combustibility”) and EN ISO 171
26、6 (“gross calorific potential”) deal with material characteristics and are thus independent of the end-use application of the product, the mounting and fixing2instructions presented apply to EN 13823, EN ISO 9239-1 and EN ISO 11925-2. Technical specifications refer to EN 13501-1 for the assessment o
27、f reaction to fire performance. The EN 13501-1 refers to the five supporting test standards for determination of the relevant parameters. In principle a product standard should not refer directly to the test standards. However, where EN 13501-1 and the test standards do not fully define the mounting
28、 and fixing of a product in a test, the relevant product standard may add instructions to ensure that the test result is representative of the product behaviour in one or more end-use applications when exposed to a fire in the relevant fire scenario. In the absence of standard mounting and fixing ru
29、les, a test result is only valid for the end-use application that is represented by the mounting and fixing (and other test configuration aspects) used in the test3. As a consequence all other end-use applications have to be tested. EN 13501-1, test standards and substrate standard EN 13238 contain
30、some aspects of standardised mounting and fixing, to some degree limiting the number of tests to be performed to classify a product, which can lead to CE-marking. To limit the number of tests further, standardised mounting and fixing test arrangements may be introduced in the technical specification
31、s. This may reduce the number of m (b) a product (a combination of one or more materials) without taking into account the incorporation of the product in the building; or (c) a product in its end-use application (i.e. taking into account the incorporation of the product in the building). This frame
32、work should be used by technical specification writers to develop further specific rules for product groups. 1In some documents “end-use application” is used as a global indication of the use of the product (e.g. use as wall lining or ceiling lining). The more detailed description of the way the pro
33、duct is incorporated in the building in the (global) “end-use application” is then referred to as “end-use condition” (including e.g. jointing, fixing and position in relation to adjacent products). In this document the two terms are both covered by “end-use application”, in line with the definition
34、 given in EN 13501-1. 2In this document “mounting and fixing” is often abbreviated as “m mounting the applicability of the resulting classification is likely to be limited (to the end-use application(s) represented by the chosen m density; colour; surface coating; composition of product; geometry an
35、d structure, e.g. shape, number and composition of layers; substrate; method of fixing; joints, type and position; air gaps; CEN/TS 15447:200610 edges; product orientation; exposure to thermal attack. The parameters of this list that may be part of the m this may damage fixings and may open joints.
36、Thin products in contact with a support may lose a significant amount of heat to the support limiting the progress of the flame front. CEN/TS 15447:200612 5.2.2 Rules in the reaction to fire standards EN 13501-1:2002, 6.3 and 13: “Typical positions in relation to other products” (than floorings) “ar
37、e for example: Free standing: without any product immediately behind or in front of it. In this case the product shall be tested free standing with an appropriate support. On a substrate: glued, mechanically fastened or simply in contact. In this case the product shall be tested with a substrate and
38、 fastening representing the end use application.” “Taking into account the role of the substrates and the fixings on the potential contribution of a product to a fire, a single product may be classified in different classes as a function of its end use application. If only one end use is envisaged,
39、only that end use shall be tested.” “The applicability of test results obtained for products attached to a substrate is limited to the method of attachment used in the test. If generic adhesives are used, the results apply for all adhesives of the same type, applied in similar quantities. Generic re
40、fers to adhesives giving the same or higher reaction to fire classification to the product in question, as that tested. Subject to the above, generic may also apply to adhesives of a defined type (e.g. polyvinylpyrolidone, polyvinylacetate). If specific adhesives are used. the results apply only for
41、 the specific adhesives.” EN 13238:2001, 5.2: “The method of attachment, e.g, adhesive, shall be representative of end-use application. The method of attachment in end-use practice shall be reproduced in the preparation of the specimen for test i.e. end-use adhesive and end-use quantities etc. If th
42、e order in which the attachments are conducted is known, this shall also be reproduced in the test specimen e.g. if the adhesive is applied to the substrate and not to the surface product in practice, then it shall be applied to the substrate during test specimen preparation. The same or greater tim
43、e for curing and drying as used in end-use practice shall also be allowed.” EN 13823:2002, 5.2.2: “Boards that are fixed mechanically to a substrate in the end use application shall be tested fixed to a substrate using appropriate fixings. Fixings that stick out of the specimen surface shall be plac
44、ed in such a way that the specimen wing can be placed against the U-profile at the bottom and against the other specimen wing at its side, over its full length.” “Products that in their end use application are glued to a substrate shall be tested glued to a substrate.” 5.2.3 Recommendations All prod
45、ucts The method of fixing should be specified in any m&f test arrangement used. It should consist of at least the composition, type, size, position and number of fixings and including the position of supporting elements like battens. If no influence of the fixing to the reaction to fire performance
46、is expected and a product does not collapse or distort during testing, the test specimen should just be mechanically pressed by the backing board against the U-profiles of the SBI-apparatus. CEN/TS 15447:200613 Free standing products For rigid free standing products which can stand without support a
47、nd which are expected not to collapse during test, distance holders should be used between the product and the backing board and the product should be held only at the periphery of the product. For the following free standing products a supporting frame and spacers should be used (the supporting fra
48、me should be representative of the end-use application): those supported in end-use, those expected to collapse, fall apart or melt, those for which the test specimen has to be assembled from a number of smaller pieces to get the necessary test specimen size. It is recommended to use screwing to fix
49、 products to a frame. If washers are used, they should not exceed a diameter of 30 mm. The number of fixings and their spacings should be representative of the end-use application. Distance holders can be any profile of Euroclass A1 or A2, which is mounted on the backside of the frame, at the upper and lower edge of the test specimen. For samples which can stand without support, distance holders can be mounted on the front side of the backing board. Distance holders should not substantially influence the air ventilation.
