Information Source:Henan Huadong Cable Co., Ltd  Release date:2014-02-18

The continuous increase of LANs makes use of integrated wiring for commercial office building is growing, which leads to the ceiling or floor space more and more communication cable. In Europe and Asia because there is no according to the requirements for fire resistance, fire resistance and some cable poor or don't know. By contrast, North America and Mexico is completely different, the communication cable all must conform to one of the four level of fire safety, and there must be a sign. The fire resistance rating for the installation environment is different, its logo on the fire, health and safety inspection are very useful.

In addition, the fire rules around the world is also not the same. In North America, communication cable with fire regulations, and emphasizes how to reduce the flame spread, fire spread, smoke generation; in Europe and Asia, according to the rules of communication cable fire does not exist (for other building products such as retaining wall, ceiling and floor etc. the existence of fire rules) anyway, in some European countries because of the low smoke halogen free (LSZH) European cable standards, some users pay more attention to how to reduce smoke and acid gases. These standards are currently being revised, let us take a look at the development of new.

2 standard

When the fire performance of communication cable, must consider several key factors:
Fire resistance (sometimes called the circuit integrity test)
Flame spread and fire resistance
The heat release rate and total heat release
Smoke
Toxicity
Corrosive smoke

2.1 fire resistance

Fire resistance or circuit integrity testing is especially for fire control system, such as a sounder / alarm / fire alarm telephone equipment, the testing requirements can maintain the circuit integrity in particular fire conditions (e.g., at 1000 ° C fire in under 3 hours remained integrated circuit). Standard major Huadong Cable Co., Ltd. is:

IEC 60331
EN 50200

The special structure of the cable, communication cable, the general does not apply.
