According to the standard for railway applications, ENbedding items are to be tested according to EN ISOignition with a match flame equivalent.
This standard recognizes that it is not possible to cover all the combinations of situations that might arise. Textiles — Assessment of the ignitability of bedding items — Part 2: The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: Politica europea sulla normazione Normazione e professioni non regolamentate.
In this case, extinguish the test specimen and record that ignition has occurred. Textiles – Burning behaviour of bedding items — Part 3: If progressive smouldering ignition is not observed, record non-ignition unless the test specimen fails the final examination. It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette. Short test description The tests are performed in a test cabinet with a calibrated air flow.
If flaming ignition of the test specimen is not observed, repeat the test at a fresh position.

Water-tube boilers and auxiliary installations – Part 1: No flaming is allowed to continue for more than seconds after removal of ignition source, and the specimen must not burn until it is consumed within the test duration. General test methods for the ignitability by a smouldering cigarette. If progressive smouldering ignition or flaming ignition is observed in this repeat test, extinguish the test specimen, note the time the test was stopped and the reason, and record that ignition had occurred for the ignition source used.
General test methods for the ignitability by a small open flame.

Light the propane emerging from the burner tube, adjust the gas flow to the rate and allow the flow to stabilize for at least s. Inchiesta pubblica preliminare UNI: During the cigarette test the bedding item is not allowed to smoulder or fn externally 1292-1 amounts of smoke, heat or glowing after one hour from the beginning of the test.
The bedding item must not smoulder or produce externally detectable amounts of smoke, heat or glowing after 15 minutes following the removal of the ignition source. Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen. Place the ignition source in 1295-1 prescribed position. The purpose of this European Standard is to ensure that the necessary essential safety requirements according to Annex I of the Pressure Equipment 129521- are fulfilled in order to guarantee the safety of water tube boilers.
Ignition sources are applied on flat surfaces, quilts, edge tapes, underneath quilts, between sheets, etc. These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific 122952-1.

If progressive smouldering or flaming ignition of the test specimen is observed, extinguish the test specimen, note the time the test was stopped and the reason, record that ignition had occurred and discontinue testing. Standard Textiles — Assessment of the ignitability 12925-1 bedding items — Part 1: The test assembly is subjected to a gas flame for 15 seconds.
This aim will be achieved by: At least 2 original edges per specimen.
Record the extent of damage. The test specimen is located on a substrate of mineral wool, on top of a steel rig. The standard is used to assess the ignitability of bedding items when subjected to a smouldering cigarette and a match flame equivalent as ignition source.

This standard does not apply to mattresses, bed-bases and mattress pads. Leave the ignition source in position for 15 s, then remove it from the test specimen.
