The standard “IEC EN 60331-23 Tests for electrical cables under fire conditions - Circuit integrity - Part 23: Procedures and requirements - Electrical data cables”, which has its basis in a European standard and is published by the International Electrotechnical Commission (IEC), describes a test procedure for electrical data cables required to maintain circuit integrity when exposed to fire under specified conditions and the performance requirement, including the recommended flame application time.
This standard describes the means of sample preparation, continuity checking arrangements, electrical test procedure, method of burning cables and includes requirements for evaluating test results. It also covers electrical data cables used for non-rated voltage and very low voltage circuits.
In these tests, a completed cable sample of approximately 1200 mm in length is used. In the absence of a cable specification, a 90-minute flame application is recommended. Voltage protection of the cable is required to ensure circuit integrity throughout the test period, i.e. no fuses fail or circuit breakers are tripped. At the same time, no conductor is broken, i.e. the lamp does not go out.
Other standards that may be taken into consideration in the application of this standard are:
A data cable is a cable that connects two devices for the purpose of data transfer. Data cables can be divided into three main types: twisted pair cabling, coaxial cabling, fiber optic cabling. A data cable is specifically designed for data transfer. Essentially, they transmit electronic information from a source to a destination and vice versa. They are widely used in telecommunications and computing platforms, establishing connections between multiple locations throughout a network.
Data cabling is a method of connecting multiple devices within an IT network, such as PCs, printers, CCTV cameras, and servers. There are two main types of data cables: copper and fiber. There are different classes of these types of cables, which ultimately results in different standards.
The cables are run to a floor box or wall mounted point close to where the device is to be located, from a central location where a communications cabinet will be installed, in most cases all the cables will return to the same cabinet but for a large scale deployment there may be a cabinet on each floor. Fibre cables can be run much longer distances than copper, so fibre normally connects multiple cabinets together whereas copper cables connect individual devices together and return to the nearest cabinet.
Fiber is a flexible glass tube-like cable that allows light to travel long distances at high speed. Fiber cables can typically run at the following speeds: 10/100/1000/10000. They can be run from 500 meters to 2 km, depending on the speed required. There are several types of connections.
