Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 1995-12-20 to 1996-02-23
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
GLP study in accordance with recognised test guideline but: Lot/batch No.: not stated Expiration date of the lot/batch: not stated NOTE: study deemed acceptable because spectral data for test item are available, covering before and after the test period - see section 1.4 Analytical Information.
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes
Specific details on test material used for the study:
Batch No.: + 19951208
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Burning time:
ca. 720 s
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The test material formed a yellow-brown melt, which sustained a flame that propagated along a 200 mm length of the pile in approximately 12 minutes.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is non-flammable with respect to this test.
Executive summary:

The flammability of test item was detrmined according to EEC Method A10.

The test item (determined to have a moisture content of 0.2% w/w by drying to constant weight at 105ºC) was formed into a pile 250 mm long and an attempt made to ignite one end of the pile by application of a gas burner flame.

The test material formed a yellow-brown melt, which sustained a flame that propagated along a 200 mm length of the pile in approximately 12 minutes.

The test item is non-flammable with respect to this test.

Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

Description of key information

Flammability solids:

The flammability of test item was detrmined according to EEC Method A10.

The test material formed a yellow-brown melt, which sustained a flame that propagated along a 200 mm length of the pile in approximately 12 minutes. The test item is non-flammable with respect to this test.

Pyrophoric solids:

The study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied.

Substances / mixtures which in contact with water emit flammable gases:

The study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Flammable solids:

Substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period (sustained a flame that propagated along a 200 mm length of the pile in approximately 12 minutes).

Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.7.2.1, this substance should not be classified as flammable solids.

 

 

Pyrophoric solids:

The substance is known to be stable at room temperature for prolonged periods of time (days).

Therefore, in accordance with Regulation (EC) No. 1272/2008 section 2.10.4, the classification procedure for pyrophoric solids need not be applied.

 

Substances / mixtures which in contact with water emit flammable gases:

The chemical structure of the substance or mixture does not contain metals or metalloids.

Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.12.4.1(a), the classification procedure need not be applied
