European CPR regulations prescribe severe fire tests to be performed by cable manufacturers in official laboratories. Official results of these tests indicate the performance of these cables before the fire, reflected in class B2ca, Cca, Dca or Eca.

Among many other relevant aspects, cables B2ca should not propagate the fire to more than 1,5 meters. The cable Cca They should not spread the fire over 2 meters. Therefore, the installation of cables B2ca or Cca prevents a localized fire from spreading to other areas through the cable network.

In addition, the CPR provide three additional levels of classification，these additional classifications are vital when it comes to safety in case of fire.

The H1Z2Z2-K cable from SUNKEAN is Cca certified. In particular, it has obtained Cca-s1a,d0,a2 certification following EN 50575. At the same time, the cable has also passed TUV EN50618 certification, has AD7 waterproof performance, and can play a full role in solar photovoltaic power plants and industrial or residential rooftop photovoltaic installations.

1.Smoke opacity

The following performance criteria for smoke emission have been established:
s1: Little production and slow propagation of smoke
s1a: S1 with visibility over 80% (UNE-EN 61034-2).
s1b: S1 with visibility over 60% and below 80% (UNE-EN 61034-2).
s2: Intermediate values of production and propagation of smoke

s3: Neither s1 or s2

2. Fall of droplets during combustion

The following performance criteria for droplets / flamed particles have been established:

d0: No fall of droplets or flamed particles(UNE-EN 50399).

d1: Fall of droplets and flamed particles that persist for less than 10 seconds(UNE-EN 50399).

d2: Neither d0 or d1.

3. Smoke acidity

The following performance criteria for acidity have been established:

a1: Low acidity (UNE-EN 60754-2 conductivity <2,5ms/mm y pH > 4.3)

a2: Intermediate values of acid (UNE-EN 60754-2 conductivity <10 ms/mm y pH > 4.3)

a3: Neither a1 or a2

In most European countries class Cca is required in public places with a high density of people and important equipment such as: offices, schools, hotels, hospitals and suchlike.
