This GSO standard specifies requirements for the resistance to ignition of mattresses, mattress pads, divans and bed bases when tested in accordance with BS EN 597-1, BS EN 597-2 and BS 6807 including those used in areas vulnerable to arson. It does not apply to mattress protectors. The levels of ignition resistance have been set after careful consideration of the fire risk of the particular end-use environment involved. These levels do not necessarily reflect the behavior of the mattress, mattress pad, divan or bed base in a fully developed fire.
