Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

17 Nov 1995

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

yes

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks:

40 mm

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

PRELIMINARY TEST (40 MIN PILE):

The test with a hot platinum wire resulted in melting of the substance.

The substance does not catch fire, neither solid nor melted. The main test was not performed

Interpretation of results:

not classified based on GHS criteria

Conclusions:

(i) The test substance did not propagate combustion.
(ii) The test substance is not classified as highly flammable in terms of its burning characteristics.

Executive summary:

A test was carried out in accordance with EC Method A.10 and in compliance with GLP.

i) The test substance did not propagate combustion.

(ii) The test substance is not classified as highly flammable in terms of its burning characteristics.

Reference 2

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 substance is known to be soluble in water to form a stable mixture

Reference 3

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

Reference 4

Endpoint:

self-heating substances / mixtures

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 completely molten at 160°C

Description of key information

Negative test results were obtained in a flammability study. As the test substance did not propagate combustion, the substance is not classified as highly flammable in terms of its burning characteristics, EC Test A.10, Schürch 1993.

As the substance is known to be stable in contact with air at room temperature for prolonged periods of time and is soluble in water to form a stable mixture no studies are needed with respect to “Pyrophoric properties” and “Substance/ mixtures which in contact with water emit flammable gases”, respectively. No study is needed to determine self-heating characteristics because the substance has a melting point <160 °C. 

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the available information, the test substance is not classified as flammable solid, self-heating substance, pyrophoric solid or substance which in contact with water emits flammable gases in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
