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. No flaming is allowed to continue for more than seconds after removal of ignition source, and the specimen must not burn until it ne consumed within the test duration.
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.
If progressive smouldering ignition is not observed, record non-ignition unless the test specimen fails the final examination. The requirements of this European Standard take account of pressure-related hazards, which apply to water tube boilers, including failure of pressure-retaining 1295-1 due to overheating.
At least 2 original edges per specimen.
It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette. Inchiesta pubblica preliminare UNI: Politica europea sulla normazione Normazione e professioni non regolamentate. In this case, extinguish the test specimen and record that ignition has 12952-11.
Leggere attentamente le istruzioni prima di effettuare il download. Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen. During the cigarette test the bedding item is not allowed to smoulder or produce externally detectable amounts of smoke, heat or glowing after one hour from the beginning of the test.
Record the extent of damage.
If progressive smouldering or flaming ignition of the test specimen is observed, extinguish the test specimen, note the 1292-1 the test was stopped and the reason, record that ignition had occurred and discontinue testing.
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. Place the ignition source in the prescribed position.
BS EN ISO – Flame Retardants
This standard does not apply to mattresses, bed-bases and mattress pads. These test methods only evaluates the ignitability of bedding products and does not 12952- the burning behavior of a specific item. Observe the specimen for any evidence of progressive smouldering ignition or flaming ignition.
This aim will be achieved by: The test assembly is subjected to a gas flame for 15 seconds. Textiles — Assessment of the ignitability of bedding items — Part 2: This standard recognizes that it is not possible to cover all the combinations of situations that might arise.

Textiles – Burning behaviour of bedding items — Part 3: General test methods for the ignitability by a small open flame. General test methods for the ignitability by a smouldering cigarette. Why test according to this standard? Data entrata in vigore: If flaming ignition of the test specimen is not observed, repeat the test at a fresh position. Ignition sources are applied on flat surfaces, quilts, edge tapes, underneath quilts, between sheets, etc.
The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: 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 rn ignition source used.
1952-1 UNIstore Non ci sono articoli nel tuo carrello. The 129552-1 specimen is located on a substrate of mineral wool, on top of a steel rig.

Leave the ignition source in position for 15 s, then remove it from the test specimen. 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. A specific test method for bedding items, which can normally be placed on a mattress, for example: 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.
