Some installations need to maintain the power supply or the control and command of specific equipment, either to operate a safety scenario or, for example, to allow the evacuation of people.
The purpose of cable tray protection is to maintain the operational capacity of the protected cables, even during a fire. The solutions must be tested and CE marked according to EN1366-11, depending on the type of application: functionality, heat subtraction or anti-propagation.
There are other categories of equipment or products that perform equipment fire protection functions (structural steel protection, load-bearing walls, etc.) and which have their own specific test standards and classifications.
REGULATIONS
The decree of 22 March 2004, published in the “Official Journal” of 1 April 2004, implements the fire resistance classification system for construction products defined at the European level. Thus, classes R, E and I replace the designations Fire-Resistant (SF), Flame Arrestor (PF) and Firewall (CF) as soon as the corresponding European test standard is available.
| Criterion (Functions to be performed) | Former classification (1999 Decree) | Former classification (2004 Decree) |
| Mechanical strength | Fire-resistant SF | R |
| Hot gas sealing | Fire-resistant SF | (R) + E —> E |
| Mechanical strength | Fire wall SF | (R) + E —> E |
