A.5 Limitations
This classification document does not represent type approval or certification of the product.
Include the following statement when the product is being CE marked under attestation of conformity system 3:
“The classification assigned to the product in this report is appropriate to a declaration of conformity by the manufacturer within the context of system 3 attestation of conformity and CE marking under the Construction Products Regulation.
The test laboratory has, therefore, played no part in sampling the product for the test, although it holds appropriate references, supplied by the manufacturer, to provide for traceability of the samples tested.”

Background information as regards the reaction to fire performance of
cables
General
This annex provides background information concerning the reaction to fire of a product that, in its end-use application, can contribute to the generation and spread of fire and smoke within the room of origin or in a given area.
Assumptions
For all construction products, the consideration is of a fire, initiated in a room, which can grow and eventually reach flashover. This scenario includes three fire situations corresponding to three stages in the development of a fire.
The first stage includes initiation of the fire by ignition of a product, with a small flame, on a limited area of a product.
The second stage addresses fire growth. It is simulated by fire initiated on cables mounted on a vertical ladder.
In the post-flashover phase all combustible products contribute to the fire load.
The validation of the classification of products in terms of their contribution to fire growth is based on large scale scenarios. It is assumed that this classification is representative of other scenarios.
A similar simplifying assumption is made to apply the same classification to different orientations and geometries.
There is no unequivocal relationship between different behavioural characteristics, or between similar characteristics under different fire exposures valid for all products. Different classes address to a certain extent different exposures and different behavioural characteristics. Nevertheless, a higher classification should not only represent at least the same performance in each relevant characteristic, but should also represent a better performance, if all behavioural aspects relevant for the given class are considered.
The assumption is that products classified as make no contribution to fire growth or to the fully developed fire. A product classified as Ам is assumed to present no smoke hazard.
Reference scenario and fire situations for cables
EN 50399 came from work done in the large project funded by the EU called ПРЕС, fire performance of electric cables [1]. This was developed by CLC/TC 20/WG 10 and was the basis of the Extended application work developed in the CEMAC project [2].
In the same way as for other product groups, see EN 13501-1, reference scenarios were used to identify the class limits. In this case, there were two reference scenarios, a horizontal and a vertical.
The horizontal reference scenario comprises three cable ladders mounted horizontally on top of each other. They are ignited in one end with a burner giving 40 kW for 5 min, then 100 kW for another 10 min and finally 300 kW for 10 min. The supply of air is by natural ventilation.
Figure B.1 — Horizontal reference scenario for cables, from the FIPEC project [2]
In the vertical scenario, a cable ladder is mounted in a corner. The heat output from the burner is the same as for the horizontal scenario.
Figure B.2 — Vertical reference scenario for cables, from the FIPEC project [2]
The performances of the different classes are approximately as follows.
C/ass Aca
Level of highest performance corresponding to products that practically cannot burn, i.e. ceramic products.
C/ass B1ca
Products that are combustible but show no or very little burning when exposed to both the reference scenario tests and the classification test procedure EN 50399 (30 kW flame source).
C/ass B2caand Class Cca
Products that do not give a continuous flame spread when exposed to the 40 kW - 100 kW ignition source in the horizontal reference scenario; and that do not give a continuous flame spread, show a limited fire growth rate and show a limited heat release rate when tested according to EN 50399 (20,5 kW flame source).
C/ass Da
Products that show a fire performance approximately like wood when tested in the reference scenarios. When tested according to EN 50399 (20,5 kW flame source) the products show a continuous flame spread, a moderate fire growth rate, and a moderate heat release rate.
C/ass Eca
Products where a small flame attack is not causing large flame spread.
Figure B.3 shows data from a large number of tests illustrating the positioning of some of the classes.
