Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2016-11-25
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.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
yes
Specific details on test material used for the study:
Batch No.: 2000820462
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: The sample melted to a brown liquid, and then briefly ignited with a small, orange flame which extinguished on removal of the ignition source. No spreading of the flame was observed.
Interpretation of results:
not classified based on GHS criteria
Conclusions:
From the preliminary screening test the sample was seen to briefly ignite before extinguishing, therefore no further testing is required. Not a readily combustible substance of Division 4.1.
Executive summary:

The test is designed to measure the rate at which combustion moves away from an ignition source, along a train of powder according to UN Test N.1. From the preliminary screening test the sample melted to a brown liquid, and then briefly ignited with a small, orange flame which extinguished on removal of the ignition source. No spreading of the flame was observed. Therefore the test substance is not a readily combustible substance of Division 4.1.

Endpoint:
self-heating substances / mixtures
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 2016-11-22 to 2016-11-24
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)
Deviations:
no
GLP compliance:
not specified
Specific details on test material used for the study:
Batch No.: 2000820462
Test procedure:
100 mm sample cube at 140°C
Max. temp. reached:
140
Induction time (h):
24
Result:
negative outcome (no effect observed)
Interpretation of results:
not classified based on GHS criteria
Conclusions:
Test substance does not show signs of exothermic activity during the first trial, and therefore is not subject to transportation restrictions of UN Class 4 Division 4.2.
Executive summary:

The series of tests is conducted to define whether a substance will undergo spontaneous ignition or dangerous self-heating. The test is conducted in accordance with the UN Transportation of Dangerous Goods Recommendations, Test N.4. The test substance does not show signs of exothermic activity during the first trial, and therefore is not subject to transportation restrictions of UN Class 4 Division 4.2.

Description of key information

Flammability:

The test is designed to measure the rate at which combustion moves away from an ignition source, along a train of powder according to UN Test N.1. From the preliminary screening test the sample melted to a brown liquid, and then briefly ignited with a small, orange flame which extinguished on removal of the ignition source. No spreading of the flame was observed.

Self-heating substances / mixtures:

The series of tests is conducted to define whether a substance will undergo spontaneous ignition or dangerous self-heating. The test is conducted in accordance with the UN Transportation of Dangerous Goods Recommendations, Test N.4. The test substance does not show signs of exothermic activity during the first trial.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Flammability:

The test sample melted and then briefly ignited with a small, orange flame which extinguished on removal of the ignition source.

Therefore in accordance with Regulation (EC) No. 1272/2008 Table 2.7.1 the substance shall not be classified as flammable solid.

Self-heating substances / mixtures:

The test substance does not show signs of exothermic activity.

Therefore in accordance with Regulation (EC) No. 1272/2008 Table 2.11.1 the substance shall not be classified as self-heating substances and mixtures.
