23、ich may include some processing of the results from the testing of a number of specimens). A test result is expressed in terms of one or more fire performance parameter(s) 3.2 direct field of application of test results outcome of a process (involving the application of defined rules) whereby a test
24、 result is deemed to be equally valid for variations in one or more of the product properties and/or intended end use applications 3.3 extended field of application of test results outcome of a process (involving the application of defined rules that may incorporate calculation procedures) that pred
25、icts, for a variation of a product property and/or its intended end use application(s), a test result on the basis of one or more test results to the same test standard CEN/TS 15117:20055 3.4 classification process defined in the Parts of EN 13501, whereby the fire performance parameters obtained fr
26、om the results of one test, or a set of tests, or from a process of extended application, are compared with limiting values for those parameters that are set as criteria for achieving a certain classification. The relevant classes and related criteria for fire resistance, for reaction to fire and fo
27、r external fire exposure to roofs, are specified in Commission Decisions (2000/367/EC, 2000/147/EC and 2001/671/EC respectively) 3.5 product material, element or component, about which information is required (EN 13501-1). Refers to a construction product, as defined by the Construction Products Dir
28、ective (CPD), from an individual producer (i.e. the item to which the CE marking applies) (EC Guidance Paper G) 3.6 product group range of products within defined limits of variability (defined by the manufacturer or a technical specification) of the product parameters and, if relevant, end-use para
29、meters, for which the reaction to fire performance remains unchanged (does not get worse) 3.7 product parameter aspect of a product (for example thickness, composition, density) which may vary and which may or may not have an influence on the products fire performance 3.8 end use application real ap
30、plication of a product, in relation to all aspects that influence the behaviour of that product under different fire situations. It covers aspects such as its quantity, its orientation, its position in relation to other adjacent products and its method of fixing (EN 13501-1) 3.9 end-use application
31、parameter aspect of the mounting and fixing arrangement of a product reflecting/simulating its end use application (for example type of substrate, fixing method, position and type of joints) which may or may not affect the fire performance 4 Product and end-use application parameters Table 1 gives e
32、xamples of product parameters and end-use application parameters which may have to be taken into account in developing direct and extended application rules. If other parameters are found to be relevant for a given product, then these too should be considered. The technical specification of the manu
33、facturers has to define the end-use application parameters for the particular product (group) which could influence the results of the reaction to fire tests in the fire tests.

36、se gives the principles of, and rules for, the development of direct application of tests results leading to fire classification. It also lists the product parameters and end-use application parameters which need to be taken into account. Parameters will need to be examined one by one depending on t
37、he product, and the limits chosen to ensure that the basic principle, that the reaction to fire performance remains unchanged, holds. Two possibilities exist for the development and implementation of direct application rules. The first is where the rules are developed by, for example, a CEN product
38、TC (or EOTA WG) in collaboration with CEN TC127 and then these rules are written into a harmonised technical specification. These rules/limits are then applicable to all users of the technical specification. The second is where an individual manufacturer, in the absence of written rules/limits in th
39、e technical specification, develops his own rules/limits for his particular product or product group. These rules/limits then apply only to that manufacturer. In this case, however, the manufacturer shall follow the guidelines given in this document. In developing direct application rules, the conce
40、pt of lowest performance is important. This means that any change to the product or end use application parameters which goes in the direction of improving the fire performance can be relatively easily applied. Changes which go in the direction of lowering the fire performance have to be treated wit
41、h care, so as to ensure that there is no lowering of the products fire performance sufficient to lead to a lowering of (additional) class or classification. Each fire performance parameter shall be considered independently. Direct application rules may apply to an individual product, or a product gr
42、oup, each in their end use application(s). While there are commercial and technical advantages in trying to develop direct application limits for all products covered by a given harmonised technical specification, there is no specific requirement to do so. Nor is there any specific requirement to de
43、fine limits for all parameters of the product and its end use applications parameters which have an effect on fire performance. Where parameters are not given in a harmonised product specification, then manufacturers have to develop their own specific rules/ limits. Annex A gives a more detailed pre
44、sentation of possible effect of changes in product parameters on classification, and B.1 gives examples of some direct application rules. CEN/TS 15117:20057 6 Extended application 6.1 General principles for extended application Two options to establish rules for extended application are possible: by
45、 use of additional tests results which, together with the initial test result, enables consideration of a larger range of one or several product and end-use application parameters, by use of tests results and additional calculations relating the product and end-use application parameters to the fire
46、 performance. 6.2 Extended application by additional tests 6.2.1 Additional tests on one product/end-use application parameter It is assumed that only one product/end-use application parameter changes and the other parameters remain constant and that there is an initial test result on one value of t
47、he product/end-use application parameter. If the relationship between the fire performance and the product/end-use application parameter is unknown, the tests will be carried out on several variants of the parameter to assess the complete range of the product/end-use application parameter on which t
48、he extended application is required and to know this relationship. From this relationship it will be possible to predict the different levels of fire performance as a function of the levels of the product/end-use application parameter and therefore the level of classification. If for a product or a
49、product group there is an established rule about the relationship between the product/end-use parameter and the fire performance (direct application), it will be possible to optimise the additional tests, as a function of the classification result which is expected, as follows: If a fire performance parameter is known to change with the change of a product/end-use application parameter(s) in a known direction, the test can be carried out on the parameter, the variation of which is known to give the lowest (worst) classification for this product and/or its en
