3P Fire Safety Testing

Fire safety testing is carried out for the three different cable types: PVC, LSOH and LSFROH.

The three versions of a specific cable are listed independently in the 3P survey of qualified cables. A qualification of one of these cable types (for instance the cable version with PVC sheath) does not automatically lead to qualification of one of the other types (for instance the similar cable in LS0H version), since the sheathing material may critically affect both mechanical and electrical performance. Evaluation of performance for each sheathing type is always required.

The following fire safety testing is carried out for the three different cable types:

A cable with PVC sheath is verified for:
Flame retardancy according to IEC 60332-1-2 / CENELEC EN 60332-1-2

A cable in LS0H version is verified for:
Flame retardancy according to IEC 60332-1-2 / CENELEC EN 60332-1-2
Smoke density according to IEC 61034-1 / CENE LEC EN 50268-1 and IEC 61034-2, incl. Amend ment 1 / CENELEC EN 50268-2
Acidity of smoke according to IEC 60754-2 / CENELEC EN 50267-2-3

A cable in LSFR0H version is verified for:
Flame retardancy according to IEC 60332-1-2 / CENELEC EN 60332-1-2
Fire retardancy according to IEC 60332-3-24 (Cat. C) / CENELEC EN 50266-2-4 (Cat. C) or IEC 60332-3, Cat. C:1992 / CENELEC HD 405.3
Smoke density according to IEC 61034-1 / CENE LEC EN 50268-1 and IEC 61034-2, incl. Amend ment 1 / CENELEC EN 50268-2
Acidity of smoke according to IEC 60754-2 / CENELEC EN 50267-2-3
