Flammability

Link to relevant study record(s)

Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

25 Jan 2010 to 11 Feb 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

yes

Remarks:

wetting solution was added beyond the timing zone

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning time (test type not further specified)

Burning time:

0 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

Remarks:

The substance is not readily combustible solid

The substance in its delivery state was measured. The substance didn't burn down or burn up. No further testing was required.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance is classified as not readily combustible solid when tested according to UN Test Procedure N.1.

Executive summary:

A test was carried out in accordance with UN Test Procedure N.1 and in compliance with GLP.

(i) The test substance didn't burn down or burn up in a preliminary screening test was performed to determine if the test substance propagation by burning with flame or smoldering occurs
(ii) The test substance is classified as not readily combustible solid and thus not classified as highly flammable in terms of its burning characteristics.

Description of key information

Negative test results were obtained in a flammability study as the test substance could not be ignited in the preliminary test, hence the substance is not classified as highly flammable in terms of its burning characteristics.

As the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and is known to be soluble in water to form a stable mixture no studies are needed with respect to "pyropholic solid” features and "Substance/ mixtures with in contact with water emits flammable gases", respectively.
Also no study is needed to determine self heating characteristics as the substance is completely molten at 160 °C.

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

Based on the results of a GLP-compliant study and experience in manufacturing and handling the substance, the classification of the substance as flammable is not warranted in accordance with EU Directive 67/548/EEC and EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
