Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
22 November 1993
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
1992
Deviations:
no
GLP compliance:
yes
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: substance ignited and propagated combustion over 150 mm within the 4 minutes test period.

After ignition, the substance burned with an orange flame, emitting black smoke.


Interpretation of results:
other: not classified based on GHS / CLP criteria
Conclusions:
The substance was determined to be not highly flammable.
Executive summary:

The flammability of the solid substance was determined a GLP study according to EC A.10. In the preliminary screening test, the burning distance was 150 mm after 4 minutes. The substance was therefore determined to be not highly flammable.

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
The substance did not react with water during the water solubility study.
Reason / purpose for cross-reference:
data waiving: supporting information
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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
-Storage conditions of the substance: room temperature
-Experience in handling (e.g. during the density study) demonstrated that the substance does not ignite spontaneously on coming into contact with air at normal temperatures.

Endpoint:
self-heating substances / mixtures
Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 17 July 2017 to 18 July 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
Version / remarks:
Rev. 6 (2015)
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 appearance of the sample was unchanged.

Interpretation of results:
other: not classified based on GHS / 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

Not a flammable solid (EC A.10 and UN Test N.1: preliminary screening test).

No pyrophoric properties (based on experience in handling).

Not highly flammable in contact with water (based on experience in handling and structural formula).

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

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

- Since the substance was not readily combustible in the UN Test N.1, no classification is required for the CLP hazard 'Flammable solid'.

- Based on experience in handling, no classification is required for the CLP hazard 'Pyrophoric solids'

- Based on experience in handling and structural formula, no classification is required for the CLP hazard "Substances which in contact with water emits flammable gases'.

- Based on the results of UN Test N.4, no classification for the CLP hazard 'Self-heating substances' is required.
