This standard does not apply to mattresses, bed-bases and mattress pads. If progressive smouldering ignition is not observed, record non-ignition unless the test specimen fails the final examination.

Textiles — Assessment of the ignitability of bedding items — Part 2: Politica eb sulla normazione Normazione e professioni non regolamentate. 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.

Unless large parts of the eb are consumed by the test, repeat tests can be carried out on the same specimen. Place the ignition source in the prescribed position. This standard recognizes that it is not possible to cover all the combinations of situations that might arise. The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: Introduzione I corsi di formazione Calendario Archivio corsi.
Short 129552-1 description The tests are performed in a test cabinet with a calibrated air flow.
Inchiesta pubblica preliminare UNI: The test specimen is located on a substrate of mineral wool, on top of a steel rig. A specific test method for bedding items, which can normally be placed on a mattress, for example: During the cigarette test the bedding item is not allowed to smoulder or produce externally detectable amounts of smoke, fn or glowing after one hour from the beginning of the test.

Leggere attentamente le istruzioni prima di effettuare il download. Data entrata in vigore: Leave the ignition source 129522-1 position for 15 s, then remove it from the test specimen.
According to the standard for railway applications, ENbedding items are to be tested according to EN ISOignition with a match flame equivalent.
Specific test methods for the ignitability by a small open flame. 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 aim will be achieved by: Record the extent of damage. These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific item.
Why test according to this standard? Standard Textiles — Assessment of the ignitability of bedding items — Part 1: 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.
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. 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.
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. Water-tube boilers and auxiliary installations – Part 1: If flaming ignition of the test specimen is not observed, repeat the test at a fresh position.
It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette. 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. 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.
