Description of key information

Not flammable

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The test substance was tested for flammability potential according to the internationally accepted EU method A.10.

The test substance burned up marginally in a yellow orange flame under formation o sparks leaving charred residue, but no sign of flammability were observed.

The formation of sparks in the flame of the burner does not indicate flammability. The sparks are caused by the flame of the burner. The gas flow “blows” fine particals of the test substances away which burn immediately in the flame, producing sparks.

Therefore, the test item is considered as not flammable.

The screening test produced a negative result. Thus, no further testing is necessary.

Justification for classification or non-classification

According to Regulation CLP 1272/2008, powdered, granular or pasty substances or mixtures shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 4 seconds or the rate of burning is more than 2,2 mm/s.

Criteria for flammable solids are:

Category 1:Burning rate test

Substances and mixtures other than metal powders:

(a) wetted zone does not stop fire and

(b) burning time < 45 seconds or burning rate > 2,2 mm/s

Category 2:Burning rate test

Substances and mixtures other than metal powders:

(a) wetted zone stops the fire for at least 4 minutes and

(b) burning time < 45 seconds or burning rate > 2,2 mm/s

In many cases, a simple screening test (see Section 2.7.4.4) can be used to determine whether a solid should be classified as flammable.

A screening test was performed on the test item: it burned up marginally in a yellow orange flame under formation o sparks leaving charred residue

However, the formation of sparks in the flame of the burner does not indicate flammability. The sparks are caused by the flame of the burner. The gas flow “blows” fine particals of the test substances away which burn immediately in the flame, producing sparks.

The screening test produced a negative result, no further testing is necessary. The substance is not classified as flammable.
