If other parameters are found to be relevant for a given product, then these too should be considered. The technical specification of the manufacturers has to define the end-use application parame

38、ples for direct application This clause 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
39、be examined one by one depending on the 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 deve
40、loped by, for example, a CEN product 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
41、absence of written rules/limits in the 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 developin
42、g direct application rules, the concept 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 fi
43、re performance have to be treated with 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 a
44、n individual product, or a product group, 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
45、 there any specific requirement to define 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/ limi
46、ts. Annex A gives a more detailed presentation of possible effect of changes in product parameters on classification, and B.1 gives examples of some direct application rules.

47、ication 6.1 General principles for extended application Two options to establish rules for extended application are possible: by 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 par
48、ameters, by use of tests results and additional calculations relating the product and end-use application parameters to the fire 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 a
49、pplication parameter changes and the other parameters remain constant and that there is an initial test result on one value of the 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 the extended application is required and to know this relationship. From this relationship it will be possible to predict the different lev
