LSF vs LSHF Cables Flame Test

LSF vs LSHF -Cables There is a difference

To clear up the confusion that still remains over the difference between LSF (Low Smoke and Fume) and LSHF (Low Smoke Halogen Free) cables, we have recorded a very simple cigarette lighter test to show the difference.

Using a the same piece of unscreened data cable in both LSF and LSHF version, a simple cigarette lighter flame was applied to both cable. The results are startling.

As you can see the LSF cable very quickly begins to burn and give off black smoke.

By contrast, see how the LSHF cable burns cleanly when exposed to the same heat source. The sheath swells and will eventually burn through in the same way as LSF but it is only producing a tiny amount of white smoke and almost no flame.

As a rule of thumb, if the application calls for a data, signal or control cable in LSF, question it.

If its a public access building such as an airport, hospital, prison, or hotel, or indeed anywhere that the evacuation in the event of a fire may be restricted you will almost certainly need a LSHF cable.
