Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

pyrophoric liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Reference 2

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 3

Endpoint:

flammable gases

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

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

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2009-10-08

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Remarks:

Study according to Test A10 of Annex V of 67/548/EEC

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

Test A10 of Annex V of 67/548/EEC

Deviations:

not specified

GLP compliance:

no

Specific details on test material used for the study:

- Analytical purity: > 98% GC purity
- Dry content: 98.3 % w/w
- Lot/batch No.: 561058
- Storage condition of test material: room temperature

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

0 min

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

The substance melted but did not burn when applying the gas burner for two minutes. Only the preliminary test was performed.

As the preliminary test showed that Bis-MPA is not flammable, no further test was performed.

Interpretation of results:

non flammable

Conclusions:

Bis-MPA is a non-flammable solid.

Executive summary:

In a study according to 67/548/EEC A.10, Bis-MPA was shown to be non-flammable.

Description of key information

In a study according to 67/548/EEC A.10, Bis-MPA was shown to be non-flammable.

The substance is neither pyrophoric, nor emits flammable gasses in contact with water and therefore not be classified as flammable solid, pyrophoric solid or flammable in contat with water according to the CLP-regulation.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The test performed according to Test A10 of Annex V of 67/548/EEC showed that Bis-MPA is not flammable.
