flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

22.06.2016

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Remarks:

not performed according to GLP

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

no

Key result

Test procedure:

other: burning time over 100 mm length

Burning time:

2 min

The test item is not highly flammable.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not highly flammable. Burning time > 45 s and burning rate < 2.2 mm/s, thus the classification criteria for flammable sollids are not met.

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

Description of key information

m-Toluic acid can be designated as not highly flammable, has no pyrophoric properties and does not emit flammable gases in contact with water.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability of solids

The test item is not highly flammable. Burning time > 45 s and burning rate < 2.2 mm/s, thus the classification criteria for flammable solids are not met.

Flammability in contact with water

The substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water (cf. section 1, Annex XI of Regulation (EC) 1907/2006).

Pyrophoric properties

This substance does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20 °C). m-Toluic acid is present in a stable oxidation state. Furthermore, long-term industrial experience in handling shows that the substance does not ignite in contact with air (cf. section 1, Annex XI of Regulation (EC) 1907/2006).

Justification for classification or non-classification

m-Toluic acid is not "highly flammable" according to the criteria of the regulation (EC) 440/2008, A.10 "Flammability (solids)", has no pyrophoric properties and does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable.

According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations, m-toluic acid does not have to be classified as flammable. According to the criteria of regulation (EC) No 1272/2008 and its subsequent adaptations, m toluic-acid does not have to be classified and has no obligatory labelling requirement for flammability.
