General test methods for the ignitability by a smouldering cigarette. If flaming ignition is not observed in the repeat test, continue to observe both test sites for evidence of progressive smouldering ignition. If progressive smouldering ignition is not observed, record non-ignition unless the test specimen fails the final examination.

In this case, extinguish the test specimen and record that em has occurred. These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific item.

Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen. Specific test methods for the ignitability by a small open flame. 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. It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette.

Data entrata in vigore: Why test according to this standard? 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.

Water-tube boilers and auxiliary installations – Part 1: 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.

Textiles — Assessment of the ignitability of bedding items — Part 2: 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. If sn smouldering ignition or flaming ignition is observed in this repeat test, extinguish the test specimen, note the time the test was stopped 129952-1 the reason, and record that ignition had occurred for the ignition source used.

This standard does not apply to mattresses, bed-bases rn mattress pads. 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.

A specific test method for bedding items, which can normally be placed on a mattress, for example: No flaming is allowed to continue for more than 12925-1 after removal of ignition source, and the specimen must not burn until it is consumed within the test duration. Short test description The tests are performed in a test cabinet with a calibrated air flow. Leave the ignition source in position for 15 s, then remove it from the test specimen.

BS EN ISO – Flame Retardants

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 19252-1 of the ignition source.

Inchiesta pubblica preliminare UNI: The test specimen is located on a substrate of mineral wool, on top of a steel rig. Introduzione I corsi di formazione Calendario Archivio corsi. Record the extent of damage.

Ignition sources are applied on flat surfaces, quilts, edge tapes, underneath quilts, between sheets, etc. This aim will be achieved by: According to the standard for railway applications, ENbedding items are to be tested according to EN ISOignition with a match flame equivalent.
