This standard recognizes that it is not possible to cover all the combinations of situations that might arise.
This aim will be achieved by: The test specimen is located on a substrate of mineral wool, on top of a steel rig. Observe the specimen for any evidence of progressive smouldering ignition or flaming ignition. These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific item.
At least 2 original edges per specimen. If flaming ignition is not observed in the repeat test, continue to observe both test sites for evidence of progressive smouldering ignition.
Water-tube boilers and auxiliary installations – Part 1: 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.
BS EN ISO – Flame Retardants
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.
If flaming ignition of the test specimen is not observed, repeat the test at a fresh position. 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 small open flame. Short test description The tests are performed in a test cabinet with a calibrated air flow.

According to the standard for railway applications, ENbedding items are to be tested according to EN ISOignition with a match flame equivalent. During the cigarette test the bedding item is not allowed to smoulder or produce externally detectable amounts of smoke, heat or e after one hour from the beginning of the test.

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.
General test methods for the ignitability by a smouldering cigarette. The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: The purpose of this European Standard is to ensure that the necessary essential safety requirements according to Annex I of the Pressure Equipment Directive are fulfilled in order to guarantee the safety of water tube boilers.
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. Specific test methods for the ignitability by a small open flame.

This standard does not apply to mattresses, bed-bases and mattress pads. The test assembly is subjected to a gas flame for 15 seconds. Carrello UNIstore Non ci sono articoli nel tuo carrello. The requirements of this European Standard take account of pressure-related hazards, which apply to water tube boilers, including failure of pressure-retaining components due to overheating.

Data entrata in vigore: Why test according to this standard? If progressive smouldering ignition is not observed, record non-ignition unless the test specimen fails 122952-1 final examination. Materials that can be tested according to this standard Mattress covers, underlays, incontinence sheets and pads, sheets, blankets, electric blankets, quilts duvets and covers, pillows whatever the filling and bolsters, pillowcases.
Standard Textiles — Assessment of the ignitability of bedding items — Part 1: Leave the ignition source in position for 15 s, then remove it from the test specimen. Record the extent of damage. Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen. It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette.
A specific test method for bedding items, which can normally be placed on a mattress, for 129522-1 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. Ignition sources are applied on flat surfaces, quilts, edge tapes, underneath quilts, between sheets, etc.
In this case, extinguish the test specimen and record that ignition has occurred. Place the ignition source in the prescribed position.
