Fire testing of cables: comparison of SBI with FIPEC/Europacable tests

It was found that while SBI does not enable the cables to be ranked in terms of flame spread, for other parameters (THR600s, HRRpeak, FIGRA, TSP), both methods can be adequate, even if for cables with very high fire performance (e.g. as required for installation in some hidden voids), more stringent scenario(s) might be needed. A number of possible pitfalls have been highlighted, for the future possible use of those methods for the harmonized classification of cables.
