1. INTRODUCTION

This expert judgement report with classification defines the function in fire classification assigned to element „ Cable bearing system and fireboxes BAKS with cables business Tele-Fonika Kable sp. z o.o.

S.K.A. at raised access floor” in accordance with the classes given in DIN 4102-12: 1998-11.

This test was carried out according to standard STN 92 0205: 2012 and meets requirements of DIN 4102-12: 1998-11. Basic deviation in process and carrying out of test between these standards is in measuring and in control of temperature in the test furnace. According to STN 92 0205: 2012, plate thermometers according to EN 1363-1 are used. According to DIN 4102-12: 1998-11, common thermocouples of construction which was used for this measurement till issue of EN 1363-1 are used.

Measurement by plate thermometers acc. to EN 1363-1 can be considered as stricter method of temperature control in test furnace in compare with thermocouples used till issue of EN 1363-1. Therefore, it is possible to use results of test according to STN 92 025: 2012 for classification of tested cables according to DIN 4102-12: 1998-11, but not conversely.

This expert judgement report defines field of application which is outside the field of direct application according test standard or outside the field of extended application according to relevant extended application standard. This expert judgement expresses the opinion of the FIRES and is based on the experience or internal rules of FIRES.

4.3 FIELD OF APPLICATION

This classification is valid for the following end use applications:

§ throughout the period during which circuit integrity is to be maintained, neighbouring building components shall not have a negative effect on circuit integrity;

§ although testing is only carried out on cables arranged horizontally, test results also apply to cables arranged either diagonally or vertically (e.g. risers), as long as the cable system is supported in transitional areas (i.e. where it switches from a horizontal to a vertical arrangement) in such a manner that the cables will not slip or kink at corners;

§ test results of function in fire test of cables tested at standard supporting construction are also applicable for tested standard supporting construction of other producers;

§ test results of function in fire test of cables tested at standard supporting construction are also applicable for cables of other producers tested at standard supporting construction;

§ maximal length of increasing routing shall be 3500 mm with consistent horizontal placing of cable with minimal length of 300 mm (apart from cable bending) and with maximal spacing of clips of 300 mm, eventually the cables are stabilized by cable transmissions at floor or ceiling with particular fire resistance;

§ for vertical systems, the test results obtained for cables mounted singly on the ceiling using single clips apply. Brackets of proven suitability may also be used, as long as their spacing is equal to that of the single clips tested;

§ results of testing single cables on the ceiling apply also to cables mounted horizontally on walls;

§ results of testing bunched cables on a ladder or tray also apply to support construction attached to a wall. However, such constructions required proof of suitability by means of a test certificate or other document issued by an accredited testing laboratory.

5. LIMITATIONS

Load-bearing construction elements for fixing of cable systems must be proved for at least the same fire resistance compare to classified function in fire of cable system.

This classification document does not represent type approval or certification of the product.

The classification is valid until 25. 10. 2018 provided that the product, field of application and standards and regulations are not changed.
