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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In a statement it was concluded that the substance is ‘not highly flammable’ in contact with water. The statement was based on the molecular structure of the substance and based on experience in handling (during the water solubility study). In accordance with UN RTDG/MTC/Appendix 6/Screening procedures/Section 5.3 for substances which in contact with water may react to emit flammable gases, no further data are required.
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
01 July 2011- 21 October 2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
(2008)
Deviations:
no
Qualifier:
according to
Guideline:
other: UN no. ST/SG/AC.10/11/Rev.5: Part III: Classification Procedures, Test Methods and Criteria Relating to Class 2, Class 3, Class 4, Division 5.1, Class 8 and Class 9, Test N.1: “Test Method for Readily Combustible Solids” (2009)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Burning time:
495 s
Remarks on result:
other: After removal of the ignition source, propagation of combustion was observed. The burning time over a distance of 200 mm was 495 seconds.

The flame of the gas burner did ignite the test substance pile. The test substance burned with a yellow/blue flame and turned into a charred residue.

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. The performance of the burning rate main test is not required.

Interpretation of results:
other: not classified based on GHS or CLP criteria
Conclusions:
The substance is not a flammable solid.

Endpoint:
pyrophoric solids

Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In a statement it was concluded that the substance has no pyrophoric properties. The statement was based on the molecular structure of the substance and based on experience in handling. In accordance with UN RTDG/MTC/Appendix 6/Screening procedures/Section 5.2 for substances which may be liable to spontaneous combustion, no further data are required.
Endpoint:
self-heating substances / mixtures
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 January 2014 - 18 February 2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
Version / remarks:
Rev. 5 (2009)
Deviations:
no
GLP compliance:
yes
Key result
Test procedure:
100 mm sample cube at 140°C
Result:
negative outcome (no effect observed)

After the experiment, the consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test substance was observed.

Interpretation of results:
other: not classified based on GHS or CLP criteria
Conclusions:
The substance is not self-heating.

Executive summary:

In a GLP study according to UN Test N.4, a negative result was obtained using a 10 cm sample cube at 140°C. From this it was concluded that the substance is not self-heating.

Description of key information

The substance is not highly flammable by ignition (flame), not highyly flammable in contact with water and has no pyrophoric properties.

Also not a self-heating substance (UN Test N.4).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The flammability by ignition test was performed in accordance with EC A.10. The flammability in contact with water and the pyrophoric properties were based on the molecular structure of the substance and/or on experience, in accordance with EC A.12, EC A.13 and UN.

In the EC A.10 test, the flame of the gas burner did ignite the test substance pile but the burning time over a distance of 200 mm was > 4 minutes.

In a GLP study according to UN Test N.4, a negative result was obtained using a 10 cm sample cube at 140°C. From this it was concluded that the substance is not self-heating.

Justification for classification or non-classification

Not classified for flammability in accordance with the CLP Regulation
