Reference

Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Oct 06, 2009

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Justification for type of information:

UN Test N.1 is now the preferred method to address solid flammability under Regulation (EC) method 1272/2008 (CLP). Whilst this study was performed to EC method A.10, both the UN and EC methods feature almost identical preliminary test methods. As only a preliminary test was performed in this study, the test is valid to determine the classification of the test item under CLP.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

no

Specific details on test material used for the study:

Dry content: 99.8% m/m

Key result

Test procedure:

burning rate test: preliminary screening test

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

Not flammable

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The substance melted but did not burn when applying the gas burner for two minutes so only a preliminary test was performed. The test item is no classified as a flammable solid under EU CLP.

Executive summary:

The substance melted but did not burn when applying the gas burner for two minutes so only a preliminary test was performed. The test item is no classified as a flammable solid under EU CLP.

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:

self-heating substances / mixtures

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

Reference 4

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

Description of key information

The substance melted but did not burn when applying the gas burner for two minutes so only a preliminary test was performed. The test item is no classified as a flammable solid under EU CLP.

Self-heating is a reaction with oxygen in the air. As sodium formate is fully oxidising, no self-heating reaction can occur.

Pyrophoric solids: sodium formate is known to be stable in air.

Substances / mixtures which in contact with water emit flammable gases: the substance is known to be stable in water.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the experimental result, sodium formate is classified as non flammable.
