TEST
FLAMMABILITY OF IGNITABILITY
OF BEDDING ITEMS, MATTRESSES AND UPHOLSTERED DIVANS
WITH THE METHODS ACCORDING TO PN-EN
597-1, PN-EN 597-2, PN-EN ISO 12952-1, PN-EN ISO 12952-2 AND
IMO
2010 FTP CODE PART 9
Principle
of the test.
The
method is designed to test the flammability of bedding components,
such as blankets, duvets, bedspreads, pillows and mattresses,
including thin, lightweight mattresses used on top of other
mattresses. The
flammability test of bedding components consists of the interaction
of small flame sources For samples corresponding to the actual
element of the bed linen and the observation of the effects of this
impact. The horizontal position of the sample is placed on a metal
base with a smoldering of a cigarette covered cotton-wool pad and a
flame of a gas burner with a heat output equivalent to the flame of a
burning match. A
smoulderable insulation of cotton-wool pad on a smouldering cigarette
is used as a smouldering ignition source, which is intended to
simulate possible smoulderable materials used in bedding.
Stand
for the testing the assessment of ignitability of bedding items,
mattresses and upholstered divans
Test
specimen
The
specimens shall be representative of the whole product to be tested.
If possible, the specimens shall be taken in such a way that
ignition can also be started along seams and their intersections. The
top side is exposed. Where there is doubt as to which side is the top
side, the test shall be carried out on both sides. Four additional
specimens are then needed.
Mattresses.
Sufficient
material shall be available for making at least four specimens with
dimensions 450 mm x 350 mm in full nominal thickness. For testing of
mattresses with removable covers, sufficient material shall be
available for the making of at least eight specimens, four with and
four without the mattress cover, with dimensions 450 mm x 350 mm in
full nominal thickness.
Pillows.
Four
samples in full size shall be available.
Other
than mattresses and pillows. Four
specimens each of size 450mmx350mm shall be cut from each sample.
If the product contains loose filling material, the edges shall be
sewn. It is advisable to sew the seams before cutting the specimens
in order to avoid loss of filling material.
Evaluation
of results. If,
within 1h of the application, the ignition sources no progressive
smouldering
ignition or flaming ignition
of any element of the upholstered system is observed, the result of
the test of this system shall be considered positive.
Applying
research methods:
- civil engineering,
- shipbuilding (requirements according to IMO 2010 FTP Code Part 9),
- UK requirements (requirements of the norm BS 7177).
