The following equipment and components can be integrated in the assembly at the discretion of the manufacturer: The bedding item must not smoulder or produce externally detectable amounts of smoke, heat or glowing after 15 minutes following the removal of the 1252-1 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. Record the extent of damage. 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.

This standard recognizes that it is 1295-21 possible to cover all the combinations of situations that might arise.

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 1295-21, pillowcases. Standard Textiles — Assessment of the ignitability of bedding items — Part 1: If progressive smouldering or flaming ignition of the test sn 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 test assembly is subjected to a gas flame for 15 seconds.

Leave the ignition source in position for 15 s, then remove it from the test specimen. Why test according to this standard?

According to the standard for railway applications, ENbedding items are to be tested according to EN ISOignition with a match flame equivalent. Short test description The tests are performed in a test cabinet with a calibrated air flow.

Place the ignition source in the prescribed position. At least 2 original edges per specimen. Carrello UNIstore Non ci sono articoli nel tuo 12952–1. Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen.

This aim will be achieved by: Water-tube boilers and auxiliary installations – Part 1: In this case, extinguish the test specimen and record that ignition has occurred. It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette. No flaming is allowed to continue for more than eh after removal of ignition source, and the specimen must not burn until it is consumed within the test duration.

If flaming ignition is not observed in the repeat test, continue to observe both test sites for evidence of progressive smouldering ignition. 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 21952-1 the beginning of the test. This standard does not apply to mattresses, bed-bases and mattress pads.


If flaming ignition of the test specimen is 129522-1 observed, repeat the test at a fresh position. 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.

These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific item. Specific test methods for the ignitability by a small open flame. General test methods for the ignitability by a small open flame. The purpose of this European Standard 129952-1 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.

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

The requirements of this European Standard take account of pressure-related hazards, which apply to water tube boilers, including 129552-1 of pressure-retaining components due to overheating.
