Rate of spread of flame

Rate of spread of flame

Rate of spread of flame.

Here the textile will ignite when a small ignition source is applied. The rate of burning after the ignition source is removed or the total distance the flame has travelled is recorded. This indicates the textile will burn slowly to reduce risk of rapid spread of the ignition source.

Very rapid surface spread of flame is possible and this requires special testing of what is known as surface flash.

This is an example where testing is key to understanding the behaviour of textiles under specific conditions.
