Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

23 January - 22 April, 2015

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Test substance is adequately specified with isomer purity. Therefore full validation applies.

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

Principles of method if other than guideline:

Not applicable

GLP compliance:

yes (incl. QA statement)

Remarks:

UK GLP compliance programme (inspected on 05 February 2014 / signed on 07 October 2015)

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: ignites but no propagation

The test substance melted on application of the ignition source and burned with a yellow flame, but combustion ceased immediately on removal of the burner flame. There was no propagation along the test pile. No further testing was necessary.

The result of the preliminary screening test obviated the need to perform the main test.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance is NOT classified as a flammable solid according to Regulation (EC) N°1272/2008 (CLP) and UN GHS criteria.

Executive summary:

The test substance was tested for its flammable properties following UN TDG Method N.1.

The test substance melted on application of the ignition source and burned with a yellow flame, but combustion ceased immediately on removal of the burner flame. There was no propagation along the test pile. No further testing was necessary.

The test substance was found not to be highly flammable as it did not propagate in the preliminary screening test.

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

the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for pyrophoric properties is deemed unnecessary based on the chemical structure that does not fall into critical categories described in ECHA guidance, and based on the experience in handling, testing and use of the substance.

Reference 3

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for flammability if contact with water is deemed unnecessary based on the chemical structure that does not fall into critical categories described in ECHA guidance, and based on the experience in handling, testing and use of the substance.

Description of key information

No propagation in contact with a flame: not a flammable solid (CLP/GHS).
Flash Point=142°C: not a flammable liquid (GHS, low melting solid).
Not flammable if contact with air or water (waived).

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Fully reliable GLP experimental studies are available:

Flammability of solids was evaluated according to UN N1 method, and is presented under point 4.13. Additionally, as a low melting solid, the substance was also tested for Flash Point according to ISO/EU closed cup method, and is presented under point 4.11. Both are considered as key studies.

Based on the chemical structure and experience, no flammable properties are anticipated if contact with air or water, therefore studies were deemed unnecessary.

Justification for classification or non-classification

According to Regulation (EC) No.1272/2008 (CLP) and UN Globally Harmonised System (GHS) criteria, the substance as solid did not propagate combustion in the preliminary test, the substance is NOT classified as a flammable solid.

The Flash Point result is above the threshold value of 93°C of UN Globally Harmonised System (GHS), therefore the test substance is NOT classified as a flammable liquid.

As the substance is still solid at the upper classification threshold of 60°C, the Flash Point is not relevant for CLP criteria.
