Materials that can be tested according to eb standard Mattress covers, underlays, incontinence sheets and pads, sheets, blankets, electric blankets, quilts duvets and covers, pillows whatever the filling and bolsters, pillowcases.

Ignition sources are applied on flat surfaces, quilts, edge tapes, underneath quilts, between sheets, etc.

This standard does not apply to mattresses, bed-bases and mattress pads. The requirements of this European Standard take account of pressure-related hazards, which apply to water tube boilers, including failure of pressure-retaining 12925-1 due to overheating. Observe the specimen for any evidence of progressive smouldering ignition or flaming ignition.

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 bedding item must not smoulder or produce externally detectable amounts 12952- smoke, heat or glowing after 15 minutes following the removal of the ignition source.

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. In 1292-1 case, extinguish the test specimen and record that ignition has occurred.

Data entrata in vigore: Record the extent of damage. Leave the ignition source in position for 15 s, then remove it from the test specimen. Short test description The ej are performed in a test cabinet with a calibrated air flow.

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. This standard recognizes that it is not possible to cover all the combinations of situations that might arise.

Introduzione I corsi di formazione Calendario Archivio corsi. Leggere attentamente le istruzioni prima di effettuare il download. According to the standard for railway applications, ENbedding items are to be tested according to EN ISOignition with a match flame equivalent.

Water-tube boilers and auxiliary installations – Part 1: Politica europea sulla normazione Normazione e professioni non regolamentate. Textiles — Assessment of the ignitability of bedding items — Part 2: If flaming ignition of the test specimen is not observed, repeat the test at a fresh position.

The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: If flaming ignition is not observed in the repeat test, continue to observe both test sites for evidence of progressive smouldering ignition. Textiles – Burning behaviour of bedding items — Part 3: 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.

Place the ignition source in the prescribed position. 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. At least 2 original edges per specimen. 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.

Inchiesta pubblica preliminare UNI: It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette. Specific test methods for the ignitability by a small open flame. The test specimen is located on a substrate of mineral wool, on top of a steel rig.

The test assembly is subjected to a gas flame for 15 seconds. Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen. General test methods for the ignitability by a small open flame.

These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific item.

A specific test method for bedding items, which can normally be placed on a mattress, for example: Why 12925-1 according to this standard?

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.

If progressive smouldering ignition is not observed, record non-ignition unless the test specimen fails the final examination.
