The specimens should be representative of the whole product
to be tested. If possible, the specimens should 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 should be carried out on both sides. Four
additional specimens are then needed.
Mattresses: Sufficient
material should be available for making at least four specimens with
dimensions 450 mm x 350 mm in full nominal thickness. The cover should
envelop the mattress completely without wrinkles and should be secured
underneath (for instance with steel pins).
For testing
of mattresses with removable covers, sufficient material should 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 should be available.
Other than mattresses and pillows:
four specimens each of size 450 mm x 350 mm should be cut from each
sample.
If the product contains loose filling material,
the edges should be sewn. It is advisable to sew the seams before
cutting the specimens in order to avoid loss of filling material.
