The Complete Guide to Construction Products Regulation in Network Cable

CPR Rated Cable for Fire Safety.

In choosing network cable for data network, Construction Products Regulation (CPR) is critical to fire safety of buildings. There are numberless cases happened in electrical fire because of cable sparking.

The safety level of the building is a vital factor of life and property, so fire retardant and lower toxin and low smoke Ethernet cable were developed under concern and the protection from fire in the cable industry in years. CPR and its new product classification system represent a further requirement towards improved LAN cable performance and its level of safety.

Then, what exactly is CPR? CRXCabling’s getting ready for Construction Products Regulations (CPR) in network cable, and we can help you to better understand these important regulations, and determine which level of safety must be achieved in data wiring.

Classification Of CPR:

EN 50575 standard specifies the requirements for the fire performance of cables, classified in 7 Euroclasses according to their contribution to fire: Aca, B1ca, B2ca, Cca, Dca, Eca and Fca. Main classification criteria are flame spread and heat release.

Sub-classifications:

Euroclasses B To D In Terms Of Smoke, Droplet and Acidity

Smoke Density
s1 - low levels of smoke density (an LSZH cable)
s1a - LSZH over 80% light transmittance
s1b - LSZH over 60% light transmittance
s2 - Moderate levels of smoke density
s3 - Emits dense smoke - non above all

Flaming Droplets
d0 - no flaming droplets
d1 - low levels of flaming droplets
d2 - Flaming droplets - non above all

Acid Gas Emissions
a1 - Low levels of acid gas emissions
a2 - intermediate levels of acid gas emissions
a3 - Acid gases - non above all

Why CPR?

In the case of cables, whose standard application is developed in EN 50575. CPR affects only those power cables, telecommunications, data and control, to be incorporated in construction works permanently. The benefits of the cables which will be regulated by the CPR are:

Where To Apply?

Based on the risk of fire, here we provide some suggestions about how to apply the CPR-compliant cables in proper environment or circumstances. According to the amount of people or closed conditions, classifying the risk of fire level from low to very high. The below chart shows the use of applications by different risk of fire level.

Stay Compliant, Keep Safety.

As part of the commitment to meet current regulations, CRXCabling Cables are over CPR-compliant cables. You can view the full range and browse our CPR Compliant cables.
