2.  BS EN ISO 12952-3: General test to bedding items by a small open flame – Standard Brief

BS EN ISO 12952-3 specifies a general test method common to all bedding items, for assessment of their ignitability when subjected to a small open flame.

3.  BS EN ISO 12952-3: General test to bedding items by a small open flame – Product Scope

A specific test method for bedding items, which can normally be placed on a mattress, for example:

— Mattress covers;

— Underlays;

— Incontinence-sheets and -pads;

— Sheets;

— Blankets;

— Electric blankets;

— Quilts (duvets) and covers;

— Pillows (whatever the filling) and bolsters;

— Pillowcases.

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

4.  BS EN ISO 12952-1: General test to bedding items by a small open flame – Test Method

Light the propane emerging from the burner tube, adjust the gas flow to the rate and allow the flow to stabilize for at least 120 s.

Place the ignition source in the prescribed position. Leave the ignition source in position for 15 s, then remove it from the test specimen.

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.

If flaming ignition of the test specimen is not observed, repeat the test at a fresh position.

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 flaming ignition is not observed in the repeat test, continue to observe both test sites for evidence of progressive smouldering ignition. Record the extent of damage.

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 ignition has occurred.

Unless large parts of the specimen are consumed by the test, repeat tests can be carried out on the same specimen.

The second flame application shall be placed in the prescribed position not less than 200 mm from the point of the first application.
