Key result
Test procedure:
other: final tests
Remarks on result:
no reaction with water observed
Remarks:
No gas generation or spontaneous ignitions were observed during any of the tests.

The sample does not generate flammable gases in contact with water and is therefore non-hazardous.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The sample does not generate flammable gases in contact with water and is therefore non-hazardous.

according to
Guideline:
EU Method A.10 (Flammability (Solids))

Key result
Test procedure:
burning time (test type not further specified)
Remarks:
Fire train mould (250 mm long) with triangular cross section (20 mm wide x 10 mm high)
Burning time:
> 56 - < 69 s
Remarks on result:
other: Not highly flammable

Results of Preliminary Screening Test:

Burning Time (s): 92

Comments: The sample ignited producing a medium orange flame which then spread along the strip. Grey smoke was produced.

From the preliminary screening (S/T) test the sample was seen to burn in a time < 4 minutes and therefore the full range of burning rate tests are required.

Study period:
March 07 - 09, 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:

Qualifier:
equivalent or similar to
Guideline:
EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
GLP compliance:
yes (incl. certificate)
Remarks:
The Department of Health of the Government of the United Kingdom
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition within 5 minutes

No ignitions were observed during the six tests. The sample is therefore not pyrophoric.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The sample is not pyrophoric.

Description of key information

Not highly flammable solid (shortes burning time ca. 56 s, burning rate: 4.5 mm/s)

no pyrophoricity
no flammability on contact with water

Key value for chemical safety assessment

Flammability:
flammable

Additional information

The dried substance is flammable as determined in the test according to EU Method A.10., however the substance is marketed solely as aqueous solution. According to the manufacturer's experience, and available experimental evidence on a variety of alkyl sulfates, solid forms of bulk density < 400 g/L are flammable on ignition, whereas solid forms of higher bulk density > 400 g/L are non-flammable. In terms of aggregate state, this corresponds approximately to powders and granulates, respectively.

Flammability on contact with water and pyrophoric properties are excluded on the basis of the tests according to EU Method A.12 and A.13, respectively.

Justification for classification or non-classification

According to Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures, the dry substance, characterized by bulk density < 400 g/L, is considered to be a flammable solid, Category 1. However, the substance is marketed only as aqueous solution, and no risk of flammability is expected.

Flammability on contact with water and pyrophoric properties are excluded on the basis of the tests according to EU Method A.12 and A.13, respectively.
